Amplifiers! What do you have? What do you use? [Archive]

I'm curious to know what amplifiers members use and own.

Some have straightforward choices, some have many amps, some have obscure combinations (me? :)) So tell us.

Mine, in no particular order:

Technics SU-C04 a tiny integrated that sounds very nice indeed, similar to a Sugden A21. I've owned this longer than any other amp.

Promitheus TVC paired with a Quad 306. A combo that works brilliantly. Very nice.

SMSL Mini T amp. The size of a fag packet and sounds way better than you'd expect.

Cambridge Audio P80 from the mid seventies. Bit of a classic that has a modern sound. Good bit of kit, even if it is all DIN sockets.

VTL Deluxe valve pre-amp, driving a pair of Modern Tube Classics CT15 Class A EL34 monoblocks. Gorgeous sound, great with Tannoys.

JVC AX-A441 A rare Japanese integrated with very fine sound quality. Hefty beast!

Sugden Optima 80 integrated. A little known model. Sounds rather good driving the Tannoys.

MingDa MC-9 TVC driving a Monarchy Audio SM-70. Amazingly lucid combination. Pure Class A.

Also knocking about, a Little Bear passive pre-amp, an FX Audio 6J1 valve pre-amp that cost peanuts and sounds amazing.

I've had literally hundreds of amps, but have kept only those that sound good to me.

As you can see, I have too many, so no doubt there be a 'thin down' sooner or later! :D

i use a pair of proart amps in monoblock configuration. also use active q acoustics. I have a backup proart and a japanese market pioneer amp that sounds very good too.

2nd system:

aye, few years now geoff. work well enough in my system, which is pretty simple on face of it but has a few odd connections. the yiang sheng dac in its pre configuration, aids volume control(saves altering 3 vcs) but both amps have a vc too. it also feeds the actives simultaneously as the pre has 2 outputs. the actives act as a sort of big tweeter, and also feed a sub to extend bass a little.
Whole kit is run from a power inspired unit and the amps all switch on via a smart phone controlled switch

They are very good pieces of gear Geoff. Probably not too many have heard any of it, but here in the US, the distributor is doing a good job of getting them around to most of the shows and getting some good publicity on them. I tend to like things that are a bit different, as long as they sound good and are reliable!

LFD PA2M (SE) - dual mono amplifier. Way more power and control than their stereo amps like the Zero.

Exposure IV - stereo unregulated with a massive frame transformer. This has an umbilical lead only, no RCA ins, so has to be partnered with the matching III preamp.

Currently using a Xiang Sheng DAC as a pre into Firebottle Monoblocks.

Nelson Pass inspired DCB1 preamp being constructed.

No desire to change the amplification any time soon. They sound great with anything i connect to them.

I do plan on building a first watt amp of some description in the near future.

I don't use the 606 on Tannoy duties often (I tend to use the 845 Set as I have a very small intimate listening room so a few watts go a long long way) but when I have used it, it really is a nice combination.

I'm currently on a pre/power combo of Rotel RA-03 pre and a Lyngdorf SDA-2175 power. I bought the Lyngdorf as a change more than an actual desire, even though I wasn't all that impressed with the Lyngdorf integrated amp when I had one, so given that experience I am still baffled why I bought the power amp version, except maybe the bargain price I paid. Even dafter, I didn't have a good pre to partner it with and as a stopgap I bought a chinese 6J1 valve pre and truly surprised how good it sounded with it's stock PSU. A beefier power supply brought even better sound, but having only one input and no remote means it is there to play with once in a while.

But isn't it just typical that when you are potless, some beautiful kit runs through ebay selling for silly low money, but when you have the loot and on the hunt, there is nothing nice being listed at all, or the prices rocket upwards. Typical. :steam: In the end I bought the Rotel pre for no other reasons than it was matt silver to match the Lyngdorf and had the compulsory remote control which I must have. Holy crap this Rotel pre is much better than I had anticipated and pairs really well with the Lyngdorf, although the hifi snobs may look down on it because of the name. Feck 'em :upyours:

Geoff, I used to use a little 306 with them occaionally too. Its a remarkably capable little amplifier the 306 and the 606 is similar but much more of it which you would expect as the amp topography is very similar.

I ran a little Decware flea power EL84 valve amp (1.8watts) with my Tannoys for years, I loved it although the bass left a bit to be desired the mids and higher frequencies were to die for.

I did something similar with a Chinese 'Raphaelite' 6V6 amp (beautifully made little thing). Top end was gorgeous, but again the LF lacked grip. 4 watts was pushing it a bit.

Amps
B&O Beolab 5000
Naim Supernait
Yamaha A-1

Power Amps
Yamaha AST-A10
Yamaha M-70
Yamaha MX-800 (currently on a well know auction website...)

Receivers (well, they have amplifiers in 'em!)
B&O Beomaster 5000
B&O Beomaster 8000
Yamaha CR-500

Of the integrateds, the Supernait never fails to impress me, but the Yamaha A-960II is a bit of a giant killer. Out of the power amps, the PC-5002M is an everything killer! As to the receivers, lets just say the Beomaster 8000 is one of the last components I would ever let go.

Having settled on using Quad ESLs (57s) for the last forty years, the amplification I use has to suit electrostatic speakers. At the moment the amplification used is as follows:

Pre amps
Mark Levinson ML10A (used as a phonostage) into a
Mark Levinson ML28

or a

Mark Levinson ML25 phonostage into either the ML28 or a
Mark Levinson ML26

These are connected via 15m balanced line interconnects to -

Monoblock poweramps (located directly behind each speaker, so as to minimise the length of the speaker cable):

Mark Levinson ML-2

or

Quad 510 (150W amplifier using an output transformer, but limited to 17V rms output (= 30W) for use with the Quad 57s)
or
Modified Quad 405s
(modified, 'monoblocked' and upgraded by Duncan (tubehunter) to Keith Snook Mod Level 3, with improved components: Dale PRP 1% resistors; Z-foils in key areas; new inductors and more accurate bridge components; Elna Cerafine capacitors; uprated 20A output transistors and improved power supplies using a pair of 35A bridge rectifiers and 22,000uF F&T reservoir capacitors). Further modified by me to have an non-inverting balanced line input, and sensitivity reduced to 1V for full output.

Other amplifiers available:

Quad 520 135W dual channel amplifier (used in second system)
Quad 405-1 (modified)
Quad 405-2 (modified with NET dual mono power supply)
Quad 405-2 (lightly modified)
Quad 50E monoblock amplifiers (x3)
Quad 303
Quad 303K (a 303 fited with XLR connectors)
Radford STA15 Mk.III (15w/channel fitted with Mullard (Blackburn Road) EL34 output valves, and Telefunken/Siemens & Halske small signal valves)
Cambridge P50 25W/channel integrated amp

Preamps:
Quad 33
Hafler DH101
Sugden C51
Linn LINNK phonostage (modified)

Hi Geoff,

Here's my present setup...

Main system:

Sony TA-E86B preamp, heavily modded - sounded good before the mods; sounds wonderful after modding; great clarity and dynamics.

Belles OCM-200 power amp - terrific sounding amp, very natural, open, slightly warm.

Second system:

Sugden C28 and P28 pre/power amp pair - less detailed than the main system pair, but lovely fluid, dynamic, rich sound. Wonderful combo!

Wish list includes an Onkyo Integra P308/M504 pre/power combo that I heard at someone's house - amazing clarity and effortless dynamics...quite startling really, I had no idea Japanese gear could sound so good (ingrained bias at work here).

And one of these days I'd like to try tube amps :)

Some of you seem to be collectors! Personally, I like to keep my possessions to a minimum, and keep my Audio budget in my current system. Although, I’ve got thoughts for a second, tubed system for the bedroom.

I’ve still got my Adcom 555, over 30 years old now! It probably needs a going over before I sell it, I broke the speaker terminals off many years ago from over tightening, and soldered the speaker wires directly to the terminal bases, so, I’ve got new terminals for it too.

And an Adcom preamp, remote control with built in tuner. Not the last word in detail but it’s matches very well with the amp, it’s already been gone over and recapped. It too is over 30 years old. I gave the amp and pre to my daughter, but she has given it back since.

Then I recently got a Parasound Halo 3 preamp, (if 5 years is recent) lots of inputs, very nice remote control pre, I’ve been meaning to replace it for a while now, it’s the least of my present system, but I like it so much I haven’t found what I want to replace it with.

And I bought a Forte’ Model 3, and got it in perfect condition for a steal of a price, and it has served me well, and is also in need of selling. I upgraded my speakers to these big Legacy Focus’s, and the Forte’ wasn’t up to the task.

So, I finally bought my present Krell FBP-300, and got an excellent price used. It’s the amp I’ve always wanted! And has no problems knocking these Focus’s around. I’d really like to try a pair of Martin Logan’s and see how it sounds through them.

Many of you will disagree, but I think that S/S amps are getting so good now that there is little to choose between them sound wise, although of course speakers have special needs sometimes due to sensitivity or impedances.

I agree with Russell, and put all my effort and focus into one system, maximising it.
I have just, after 7 months without music or radio, finished my lounge re-furbish and the tidying up of my ATC SCA2 preamp, and lashed up my tuner through the pre to the ADAM Betas (ICEPower).

So far, and only on FM, I'm in heaven, but the range of quality of studio/mic techniques and recordings really seems to stand out. It is really good to feel that all the endeavour was worth it.

There have been fine sounding solid state amps as long as I can remember. The main thing these days is higher powers are available and at comparatively lower cost.

A cheap budget amp from circa 1970 is the Trio KA-2000A and with sensitive speakers, it will outclass many modern amps for sound quality.........easily!

Just the bare minimum:

Main system - Radford STA25 MkIII, currently standing in for Radford STA100 that's in the final stages of restoration at Radford Revival.
Study - Pass Aleph 'M' clone

I also have a 90w tripath based chip amp done by Duncan 'tubehunter' which is a handy stand-in in emergencies.

NOT a collector in any shape or form - counting up cartridges I have 11 mono and stereo cartridges mounted up but they all have a role to play between the TD124 in the main system and 401 in the study.

Hmm, sometimes here I feel like I am still on my first bicycle with stabalisers!

My main system I have a 1990s Audiolab 8000A that I have owned since new. Now recapped and upgraded to stage 2. And used in conjunction with a Yamaha DSP-E800 DSP (also bought new, so that must be over 20 years old now too!!).

And in my second system I have a later "grey" Audiolab 8000A (late 1990/ early 2000s??).

I've got rid of a fair few over the past year so I've lost track a bit.

Power amps I've got a Krell KSA50s, a Linn LK100 and the Firebottle Dulci (EL84 SECA).

Integrateds, I am down to one, an XTZ A100 that I use in the TV system.

And Receivers, a Harmon Kardon HK930 and a Sony 5 channel AV amp, no idea of the designation but it isn't a fancy one.

Might be some others stashed away upstairs that I forgot about but I don't think so.

Currently using a Wyred 4 Sound mINT integrated with built in DAC - very good little amp with loads of power and suits my current (and recurring) box reduction phase. When in my valve phase I've had two Ming Da Piccolos over the years which I really like and am tempted to go back to since I've just completed a 4 Jordan Eikona per side TL which has 92dB sensitivity. The Jordan/Ming Da combination has always been a very satisfying combination to my ears.

When i first started in this hobby I always had an extra amp or two but I found I was always swapping them in & out & not enjoying the system, so nowadays I stick to just the one. At the moment that is a Art Audio Quintet power amp, with Definitive Audio mods & converted to just triode mode, sounds fantastic to my ears & I certainly have no plans to change. I have also recently added a Consonance Basie pre amp to the mix, having sacrificed my beloved Art Audio Vinyl One Reference phono pre for the greater good; as expected I have lose some magic but have gained some dynamism & attack, which was a little lacking before.

I've always been instinctually impressed with Krell amps, though not heard one, but an AVI salesman said that they had terrible Xover distortion, which seems unlikely.

I hope that wasn't me... Classic Krells are overkill to be sure, and overkill power supplies and the cases to take them do cost a lot of money - and then you add import duty, distributor margins and so on. The whole point about most of them running a huge amount into Class A is to remove the crossover distortion at source and I do admit the early ones biased flat out so they run hot all the while do need attention every few years to prevent damage caused by dried out caps. later models from the mid 90's onwards have plateau biasing, so if used quietly, they won't be run so hard and will actually idle cool! The KSA 50S I sold to Macca had an excellent review in Stereophile and the distortion performance at all three bias levels was clearly laid out if you can read the graphs. My issue was that I couldn't have the thing free standing fully ventilated and half an hour on the mid bias level caused the case to get almost too hot to touch. I only did this two or three times (honest Macca)...

Early 90's word from the AVI DESIGNER - not his once vociferous mouthpiece and fellow director - is that in past decades, the matching of output transistors wasn't as good as it became in the 90's, so crossover distortion could rear it's ugly head if they were only lightly biased in some applications. In some designs it can still do so and a HFW review of a Quad 909 found a trace, which may not be there in current Artera versions (the 405 versions have a tiny bit too I gather until they thoroughly warm up and fully sweeten their tone). As of the mid 90's anyway, AVI's Martin G told me the transistors coming on-stream were so much better matched in general production, that crossover distortion wasn't really an issue any more if moderate biasing was used and his amp designs seemed to bear this out I remember. AVI amps had high damping factor, which could explain a little the sometimes tonally plain-jane sonics if inappropriately used I feel. Easily fine tuned out with cable matching I found, and having the power amps right next to the speakers as recommended.

I assume that both Martin and Geoff are of the opinion that the Xover distortion on Krells is rather poor

No. I was implying the opposite. I don't know all Krell amplifier models, but if they are biased into Class A at all output levels there can be no crossover distortion.

Macca

24-06-2018, 18:13

I assume that both Martin and Geoff are of the opinion that the Xover distortion on Krells is rather poor, and this, given the price level and build quality surprise me.

It was not you David it was in fact the vociferous mouthpiece and fellow director.

No, I was being sarcastic. I've got a Krell and its very good. My understanding is that you don't get much, if any, crossover distortion in a Class A because there's no switching, and that's the whole point of using a class A topology.

DSJR

A few years ago I spoke to a guy called Robin at ATC and he measured the distortion of a class A O/P stage to determine its nature.

I was taught that class A eliminated even harmonics which class B tends to have because of crossover distortion.

Robin found class A exhibiting both odd and even, to some extent.

Hyperion HT-88s
Shindo D'yquems
EAR 861
Radford STA15 III
Leak ??? (the early one with a germanium transistor)
The EAR is the main workhorse although the Radford could well take its place after some restoration work.
They have all, apart from the Leak, been acquired to try to find the perfect amp to drive Tannoy 15" Monitor Reds in GRF Corner Horn cabinets. All I have discovered so far is that the number of watts is irrelevant, as is the valve type. PP is better than SE and early results from the Radford seem to indicate that transformers are an important factor.

No Jerry, its a 10K Dual Mono with ZFoil and Elma switch upgrades - it comes with 2 volume controls. I think that means there's no room for the remote control bits. Its only the stereo that has remote.

Thats one reason why I wanted the Schiit for its remote and tube swapping capability but TBH not having that is not a big deal.

No issues with matching equipment i get plenty of volume and its made an excellent improvement.

I'm in the midst of a change in direction regarding amps having just sold a Naim 202,200 napsc and Puresound P10, T10 combination. Whilst I source the new power amp- which will be a Radford STA25 partnered by an Audiolab 8000C- I am using my Unitiqute 2. It certainly hasn't disgraced itself and I can live with it for the time being. I have my fingers crossed that the Audiolab can perform reasonably and if it does I will leave it in the system. The MC photo stage might not be the best match for the Transfig Spirit I currently use but it could surprise me.
I have heard a Radford driving Tannoys before but I suppose that until I have one here in my set- up I won't be able to gauge whether the change of amps was worth undertaking.

Hi Dennis,

I bought the AVI with some urgency from DSJR following the failure of my LC Audio Sidewinder pre. I was attracted by its reputation for not adding anything to the original signal and also the suitability of its MC phono stage for my Denon DL-S1.

I’m pleased to say it has supplied everything I’d hoped for, especially given the excellent performance of its well modified predecessor. It’s difficult to provide a detailed assessment as I’ve not been able to carry out a direct comparison. Suffice it to say that I’ve not identified any negative attributes, it has provided a clear and open performance and I’ve been delighted with the way it has handled the rather low level output of my cartridge. The remote control, sensible number of inputs and double outputs has also eased the loss of the Sidewinder.

I’ll get the Sidewinder repaired eventually and the resulting shootout will be very interesting.

Thank you Paul, I asked because there is a slight question for me about an 'edginess' or slight brightness which it does seem to have compared with my ATC SCA2, this pointed out by a friend, and which I think I noticed when I changed over.
(But the ATC is 6X the price).

The AVI has better specs, the ATC being balanced and hence having double the distortion, but that is still very small, and it is also a very neat unit.

I think the vinyl section is better on the AVI and really works well with my Denon DL304, and Martin Grindrod's designs are very well executed IMO.

walpurgis

14-07-2018, 22:19

I also owned the AVI some years ago. I didn't get on with it. Despite presenting the sound reasonably well, it seemed a bit 'matter of fact', with a hint of blandness.

By the way, I didn't enjoy the DL-304 that much either. It tracks reasonably well for an MC, has a delicate and fairly refined sound, but for me, lacks body or impact. A DL-103R has much more presence and a ZYX R50 Bloom even more so.

The G55 is setup in bridged mode with channels 1&2 bridged to supply 300w Left and channels 4&5 bridged to supply 300w Right; channel 3 is used for the Centre channel when running a DSP surround mode.

The G61R SL has a "Direct" mode which bypasses all digital tweaks and delivers excellent stereo to the G55.

A seriously good choice of equipment on that rack. I want to get hold of one of those Technics DAC some day.Thank you. I have all that in preference to all the other stuff I've owned. NS1000M sit at the end of it and it works in my room. My 801 series 80 in a cavernous space were amazing but they wouldn't work in here.

The technics DAC is something else! $10k in 95 though so there's not many about and this one is a minter, with box and instructions!

I have 2 systems, in the solid-state system I use an Adcom GFA 555SE and in the valve system I use a Jolida Fusion 3502P Power Amplifier.
Each have their own distinct qualities.

Power amps are Audio Note Empress Silver 2A3 monoblocks, pre amp is a Hattor Passive Pre with Tekman Rey resistors. I tried quite a few pre amps with the Monoblocks including Audio Note M3 and Music First passive, in the end and in my system I found the Hattor to perform the best

Current main rig......

ARC Ref10 Pre sporting 1980's NOS 6h30DR and 1970's GE6550A valves, painfully expencive!

ARC Ref250se Mono-blocks KT180's and NOS valves as per the Pre, the latter impart such an improvment over the current production valves as supplied with the equipment one can but laugh out loud.

Hi

I use a Croft phono/pre/7 power amp set up,all “R” spec
I absolutely love the sound and think I will be
sticking with these.Also have an MF A300 which is a bit
of a solid state beast,I like it but prefer the silky
sound of the Croft set up.

That’s it,pretty simple ✅

chris@panteg

20-07-2018, 21:20

After about ten years using solid state integrated amps, I've gone back to an all valve system.
Puresound T10 SUT into the Puresound P10 and the Puresound 2a3 integrated, the synergy is obvious and matches perfectly with my Living voice Avatars.

After 10 years with a solid state McIntosh MA7000 I've gone back to a valve amp, actually a hybrid ss/valve power amp, the Radford TT100. I was recommended a Radford to match my Tannoy Cheviots.
Lucky enough to find a cheap, beaten-up one on Gumtree, restored for me by David Coe at AD Audio. Sounds fantastic!

We do like our big expensive toys that shout "look at me!" but I reckon these little amps can shame some of the bigger boys, giving 90% of the sound for 10% of the money. My little Amptastic Mini 1 is going nowhere, having proved itself as a capable stand-in, and as a permanent part of second set up :)

Hi Folks

After looking at some of the exotic (and downright obscure!) kit that members list on this thread, it sounds a little dull to just list a Cyrus 6a. It did, however, have the singular virtue of being free, in a convoluted way. When I was arranging to move from London to my mansion (ok, small apartment) in Fuerteventura, I gave my JVC JAS31 to friend. It had served me well for 40 years, but it was past time to move on.

Vickers Hifi had an offer on Cyrus refurb'd 6As - full warranty, lala. I had closed down my part-time online sales biz a couple of months earlier, in order to move. That left some cash just sat sitting in my Paypal account. Vickers accepted Paypal, so the largest part of the dead money in my Paypal account was exchanged for the Cyrus. So not really free, but a completely painless transaction!

It's the now discontinued all-analogue 6a (Current Cyrus model is the 6DAC). DAC duties are ably performed by an SMSL M6, connecting a pc and tv. The tv also connects to a 5.1 decoder, allowing the Cyrus to be used for the front speakers in a 5.0 system. Additional amplification for the 5.0 system is provided by a couple of (quaintly named) Nobsound Class D jobbies, so my amps list is:

Cyrus 6a (stereo and front surround)
Nobsound Mini (rear surround; occasional stereo)
Nobsound G2 (mono; surround centre)

Cheers,
Chris

Yeah, but at least you can see where your money is going, the finish and component quality are top notch. Should be good for about 30 years without much hassle too. Think of it like a mortgage!

I’m using a Luxman Avance Z504 which is the power amp great grandad of yours Roy so I’d probably love the new version. A friend has the M700u which is basically the power amp section I think.

Thanks guys.

Yes, the build quality is simply stunning as is the sound. The price is a little eye watering but what you get from AnthonyTD is something which will last and never miss a beat and service which is second to none.

They are not mass produced either.

Its all point to point inside using all the best components.

Having fun with a Leak Stereo 30 sounds bloody good for over 50 years old - this one original Non plus version and working which is a bonus...:)

Is there an equivalent-value/quality dac around? To put together a 'cheap as....' set-up.

Germanium transistors have a tendency to fail quite violently!

Lot's of satisfied customers for this:

https://www.amazon.co.uk/Topping-D30-Decoder-Coaxial-Optical/dp/B01JU9EA2U/ref=sr_1_2_sspa?keywords=topping+d30&qid=1559288379&s=gateway&sr=8-2-spons&psc=1&smid=A2UWBVY2W3G8CS

This is the updated version with a headphone section. I've got the older version which is identical minus the headphone section (also still available if you prefer).

DSD, USB Asynchronous, Coax, Toslink, compact. Great Dac, very neutral.

Or even cheaper one (but probably not quite as good sounding) I haven't heard this one though but probably similar sound signature.

'New' amp - Crayon CFA-1

That looks interesting Jerry, what's it like ?

To be honest I'd never heard of them...;)

No, Bev, I hadn't heard of them before Jake (lordmortlock) acquired one and seemed deeply impressed.
He's still having his valve love-in and I bought it from him on the condition that I give him 1st refusal to buy it back if I sell it on!

Weird looks. Seems like a rather large Lego brick to me. :scratch:
Crayon - weird name, I wonder what's behind that?

Only had it switched on for about half hour but very impressed so far.
A lot of kit gets the thumbs down within the first minute, but this one raised my eyebrows in a good way! A bit of an "Oooh, that's nice" moment.
Hugely "musical" - whatever that means. :lol:
Very clear and lucid throughout the range - bass is deep, taut and powerful, bit of a shock actually given the meager power rating (28wpc into 8 ohms, I think).
Soundstaging might well be astonishingly good but I'm gonna need a while to get my head round it all, I think.

It's defo a strange name Jerry..

I thought it looked quite nice though, a bit different than the norm which I like

Not cheap at 3K ish for a name I've never heard of...

If you've not given it a thumbs down so far that sounds good.... enjoy...:)

Is that new amp coloured Jerry?

I was hoping it was the version with pink stripes on a purple background.
But sadly it isn't. :(

Tonally, no, it seems uncoloured so far.
No warmth added or taken away.

One thing that stands out is that it seems to have limitless power. Astonishingly clean when loud and unsplashy dynamics.
Bit baffling with 28wpc.

Only had an hour or so with it, lots more music to try.

I'm pretty sure this is due to it being powered by an SMPS, which are really quite a bit better than linear PSUs in many respects, despite being somewhat demonised in audiophile circles ;)

SMPS are fine for non audio uses, for things like lamps, but sadly are more complex , and have ac noise voltage, both of which matter greatly
in audio related circuits.

Linear supplies are more reliable and can be designed with excellent voltage and current regulation, they are presently the
best choice for audio circuits.

Well, the amplifier in question (Crayon CFA-1) uses a state of the art medical grade (read: low EMI) SMPS made by Traco. Apparently, it sounds excellent. To achieve similar load regulation in a linear power supply, you would have to spend a lot of money. SMPS are also quieter where it matters (in the audio band). Who cares if there is residual switching noise somewhere around 200 or 400 kHz?

There are many threads on DIY Audio where people suddenly discover that reasonably priced linear PSUs are outperformed by high quality SMPS. Especially when it comes to class A amplifiers which typically have a rather poor PSRR...

It's even true for low-power applications! Something like SilentSwitcher (https://linearaudio.nl/silentswitcher) would beat the living cr@p out of pretty much any linear PSU when it comes to noise on the output.

This is also quite an interesting read: https://benchmarkmedia.com/blogs/application_notes/152143111-audio-myth-switching-power-supplies-are-noisy

But to each his own, I guess.
