Tinkering away at the front end of my system and after some thought and comparing my PPP to a mains block I decided a P10 would be a good move, courtesy of Martin T's review of a few months ago

Arrived Thursday evening in the back of Trevor from Guildford Hifi's car.

It is big and heavy.
It would *just* fit into my Mana rack as Plan A, but I decided it was too tight given the weight and glass, plug overhang and ease of moving.

Plugged in and tried one track from Mavis. Sounded good, but I wasn't expecting much. Played various not so familiar music until today then albums I know.

So how was it after being left on for just over 2 days ?

Somewhere between surprising and stunning.
Way more detail, bass that seems to be connected directly to the earth below. Some little details shocked me because there was never any clue they were there before.

I wasn't going to review this soon as I expected it to take a while to come on song.
If it gets that much better from this level it will be stunning.
Not cheap and maybe you could manage with a P5, but you really should audition one if you can

Oh yes I have an Ultimate stiffy, 2.6 from MCRU

I couldn't see why a good mains cable was so important, (surely ?) as the mains was being taken to pieces and put back together right, but did the testing and blow me so it was ...

Best cable of the lot has to go on the regenerator

Glad to hear you are finding the same as the other P10 owners here, in my system it is fundamentally necessary, introducing distortion and dc into the signal path is never a good idea.

With anything like this it best to try in your system first

ATC speakers can be plugged directly into the wall with a good mains lead to hear them at their best (as reported by several ATC owners). :)

Or use a PS Audio Powerplant, or an IsoTek Sigmas (those are the 2 most popular amongst my ATC customers.

Just checked and the latest person to use the "stiffy" as described by Mike, reports thus.....

ATC speakers do NOT work well with Isotek products. You bought my Isotek off me remember. ;) I noticed a marked improvement with the speakers when they were plugged directly into the mains. Additonally I use Polymorph reference power leads. Ruddy thick pure silver power leads with immense EMI and RFI protection amongst other things.. ;) The P10 could be another thing altogther as it does markedly different things to Isotek products.

Yes, you can't beat having a big 'stiffy', or two, or three.... :eyebrows:

In all seriousness, no mains cable I've heard is superior to The Ultimates: they have an uncanny way of unlocking the latent potential in any system, in a way no other cable can! :exactly:

Mine are indeed plugged straight into the wall and they do sound better than being plugged into a mains filtration system. I did not ignore your sentence. I have Silver reference power leads which work very well, better than any Cu version I've tried but thats just my opinion, additionally, I dont think the extra cost of higher-end Isotek products would sonically be worth the additional outlay, too subjective in my eyes. Nice to hear you got another good review.

Harry, do you trust my judgement? If so, I can tell you that, outside of a major component upgrade (such as with your Ushers), the Ultimates will provide the most astonishing sonic improvement in your system, such as you won't quite believe until you hear it...

I didn't bother with much investigation on the first night as I didn't think it could be that good from cold and new.
The improvement in sound makes you stop
the P10 is one of the biggest single improvements I have ever heard

Put a stiffy on the front end and you have heaven :eyebrows:

A P10 is mandatory with Ushers !

MikeMusic
21-01-2013, 09:19
As the P10 didn't give me enough clearance my the oversize Mana rack it had to go on top

Therefore the Isis instead of being on a Mana Ref top, on top of the rack is now in the middle of the rack

So even with that drop in position and sound quality it still way out performed the previous set up

MartinT
21-01-2013, 10:38
To add to Mike's observations, my P10 was a big leap up from the PPP, itself no mean regenerator. My household mains suffers from high voltage flat-topped sinewaves, anything from 248 - 252V at between 3 and 5% distortion. This is typical of most mains waveforms in my experience, few people are lucky to have a low distortion supply. What the P10 does is supply an immense amount of immediate-demand current to maintain the voltage no matter what the system is doing by lowering the incoming supply impedance, at an output distortion of 0.6%.

As Mike says, the sense of music coming from darkness, pinpoint focussed soundstage and subterranean extension to the bass transforms a good system into a great one. Worth the amount you might otherwise spend on upgrades once your system has reached a certain level of capability.

I too use a 2.6mm Furukawa 'Ultimate' input cable.

Marco, I certainly do trust your judgement. But I have a problem. Well eight problems. Four power amps, CD transport, DAC Pre and two PSXRs. Eight of them would be a hell of a price. Would one make a difference? What would I plug it on?

Hi guys, I'm Kevin of Signature Audio, distributors of PS Audio kit. I'm more than happy to answer your questions:

1. The most important power cable to max out on is the wall to P10. Think of filtering water. The more a good quality power cable does in cleaning the mains before the P10 the greater benefit the P10 provides. I've proved this to many disbelieving customers.

2. New P10 stock arriving very soon with me. Am currently sold out.

3. The P10 is sonically significantly better than the P500 and the PPP.

All the best

Kevin

I've now tried this and it does indeed work. I removed a mark grant 2.5 with a fururech plug and oysaide iec and instead put in an RFC with fururech plug and furutech carbon fibre iec. More texture to strings and other instruments and a more defined sound stage. Weird, but true.

I can't believe the amount of money being thrown at this system in an attempt to "improve" it, when the fundamentals of the system are so in need of a re-think IMO..

Wouldn't it have been better to get something like some ATC SCM100ASL's for instance (a perfect and well trodden upgrade from any Naim system) and have change to spare for some better looking support furniture? I no longer have any contact with ATC, but their active monitor speakers are a very well trodden path from Naim owners looking to get a better sound for less money.. ATC have also done a considerable amout of work on their drive units and amp/crossover packs since the first of the "new" type came along in 1993, which my 100A's had fitted to them. Even keeping the tired old 'briks, where the mid drivers will almost certainly have drifted off their spec by now (a well catalogued occurance by the way in the KEF B110 in any form), going active with them would bring about the kind of clarity transformation that NO passive 'brik, driven by anything on the market, could ever dream of reproducing due to very audible losses in the passive crossover..

Sorry to spoil the fun, but I respectfully believe some common sense is called for here - and lets face it, most of the bigger Linn and Naim dealers from the bad old days were unanimous in supporting the active 'Brik route, and not just because of the extra boxes we could sell, since the sound was so much better on every era of Isobarik production...

'The system' is in flux.

I knew the system needed looking at.
After hearing the sheer 'naked' sound in Martin T's system I knew I had work to do. I'm after that 'nakedness'. That is the objective.

I've tried a few things that haven't worked, fortunately at no cost.
With the exception of getting the LP12 back working all those months ago everything put in has either improved or massively improved the sound quality.
Recent kit and cables are staying as I build a better system.
Given time I will sell the upgraded kit, except that moved into other systems.

Items like The Ultimate cable, Yannis interconnects and the P10 will stay if and when I upgrade other boxes.

The recent spate of none too cheap upgrades have got me much closer to my objective. With the huge improvements there is less urgency now, although the 82 must be a weak link in the chain... but -this is my only hobby, apart from cycling. - Slight correction listening to music is my hobby. The kit has to enable that.

I like what Mana does. I even quite like the look of it ! and that is not in the frame to change, except tailor made similar items to fit kit and non magnetic to get made up
The 500 will be compared hopefully quite soon to Martin T's Chord - and anyone else who is passing with a big power amp !
:)
I love my Isobariks. They may have to go, not soon, unless a silly bargain comes along that enables me to buy, try and either move on or swap out
ATC certainly a possibility. I haven't looked at speakers

Good news : I have a system that sounds fabulous. Weak links notwithstanding.
Actions : Must sell upgraded cables and kit
Future : System will sound even better

The thing is the quality of music delivered.

Some years ago I thought you were either mental or in need of a change in medication when you went on about mains cables improving hifi sound :scratch:
Fortunately for me I was prepared to try them out
Being mostly non technical I still don't know quite what is going on. The first tryouts left me speechless for a while (not easy)

Then you seduced me into regenerators

The P10 is an awesome piece of kit and I would even say it was very good value for money :D

Anyone thinking of upgrading any part of their system would do well to look at the front end and a P10 or at least a PPP, P300 etc. depending on budget

Nice one, Harry. Your Ushers will love cleanly powered components.

I'm serious, by the way; the Ushers have supremely clean midrange and treble drivers and reveal any harshness whatsoever in the replay chain. A P10 cleans up the reproduction in this area very nicely. Did we mention the subterranean bass?

When the power goes in the building they both keep your stereo running.
Im sure your P5 will walk over it.

When I first switched it on it brought a smile to my face and I thought well worth the £600.

I'll not be replacing the P10 for quite some time! By the way, I did a firmware update on it a week ago. Stability and start-up improvements (I never had any problems) and a new feature to adjust/optimise the incoming phase. I played with it and went back to default as giving the least distortion.

I was using the P10 in vanilla mode until this week -being fairly impressed with the sound :)
Don't rate the manual at all, which I had to print myself - just managed to work out some aspects of the touch sensitive panel.
Can the remote be used for other things like turning zones on and off or do you use your clever phone ?

Right I've cracked. I'm going to dip my toe in the regenerator water.
If it hadn't been for massive hifi outlay recently I'd go shit or bust and get a P10. Sadly it's more than I can afford at the moment.
So what are my alternatives?
Problem is the number of boxes I have. My all Cyrus system comprises 8 boxes 4 x power amps, a transport, a Dac/pre and two psxr power supplies.

So, what should I go for as a stop gap until I've saved up the cash for a P10. And what will I plug into it?

I already have a decent mains supply with 8x good quality Unswitched single sockets and all my components have pretty good mains cables on them.

All help gratefully received.

A 2nd hand PPP would help with 5 outputs so choose what is connected

First of all you need to know how many watts the system draws, no point in buying a 300 watt regenerator if you need 2000 watts :)

measure each device with something like this:

Then post the watts needed for each device and we can help you spend some money :)

You dont have to have 1 output per item.

Wild idea 1 output to a mains block say 4,6 ... sockets.

Have you worked out the power requirement of all your kit? It is best the MR has a comfortable margin for peak loads. Total power requirement 900w Don't get a 1kw MR

Hi Alan. Problem is, I went from using blocks to eight single Unswitched sockets. Sounds better than using a block. Of course I didn't have a regenerator in the equation then.

The PPP is much more efficient and can power potentially your whole system. The P500 would be source components only. I've found that power amps response extremely well, so I'd go for the PPP if you can.

You will not be dissapointed with the AG1500. I am a sceptic with much that others rave about in HiFi. But the principle of rebuilding the mains to a consistent voltage and wave form is a solid one. Lo and behold as soon as I plugged mine in I could hear an improvement in SQ and grew to appreciate what it was doing (burned in) over the days that followed. Simple test just return to standard mains confirms it is no illusion. Whether you get over 4-6 times the improvement in SQ with a PS Audio I really doubt. I'm not spending £4-6k to find out. Look at he AG1500 as being plug and play, the P10 as the tweakers joy both have the same capacity. Best of luck

Assumed Underworld – A hundred days off would take advantage of the subterranean bass made available by the P10 and the Ultimate cables.
Nope
What I got was the detail of everything laid out like separate components.
Imagine a tool box with tools heaped in a pile – that was how it was before
Now it’s like the tools are all laid out separately in front of you and you can see them all
That was a surprise. The bass was ok. Assume the depths were not there in the making of the album

Anyway I got an idea and interrupted A hundred days off after one side

Once upon a time a few years ago I taped John Peel’s shows, picked out what I wanted, played them a bit more then bought what I really liked.
Worked well and JP was my main source for music.
He had a session from this lot I may have heard before but possibly not, a dance type band I guessed.
Recorded on my Revox B77, half track I listened once and thought – “hey, this lot may have something”
Played again, then and again and I was hooked. It was wonderful
This is arguably the best you will hear from them and you can’t buy it
Closest I can find is this, 9 minutes at the beginning of the session
http://www.youtube.com/watch?v=qnTFk4Tbmw4
around the middle another 10 mniutes
http://www.youtube.com/watch?v=tqSBUb8cowQ

My reel to reel had been sidelined as it sounded below par after various upgrades
Time to try again I thought
Underworld’s John Peel session
Previously muddy and lacking definition, now with the B77 plugged into the P10 with it’s bell wire mains cable, a 3 metre Russ Andrews PBJ i/c and sitting on a Mana rack *not* spiked.
The sound was quite definitely *good*. Way better than expected.
I can tweak this quite a bit or maybe a lot better

So P10 with Ultimates feeding it and the power amp works some magic.
Some more tapes to be tried out .......

I added a second AG1500 as it came up at a good discounted price and my theory was/is to plug only my 2 channel components into one (none of which have switching supplies) and everything else (lots of other boxes for multichannel, TV etc) into the other.

And that if it made no difference to take it up into my second system in my office - so win-win either way.

Nice one, Andy. I have mine set to 242V output (my input is frequently 250V+) with high regulation, which sounds better to my ears than low distortion. I also use Multiwave. Don't forget to 'clean' your system with Cleanwave before a listening session.

The P10 will gradually improve over a couple of weeks but you should hear an immediate jump in sound quality if you run the whole system from it.

Be interesting to compare one of these to my diy BPS sometime. AOS meet perhaps?

I'm likely to bring my kit to the AoS show in November, Ali. That might be an opportune time.

Good stuff Martin, I could do the same if there's room. Your speakers too? :eek:

Nice one, Andy. I have mine set to 242V output (my input is frequently 250V+) with high regulation, which sounds better to my ears than low distortion. I also use Multiwave. Don't forget to 'clean' your system with Cleanwave before a listening session.

The P10 will gradually improve over a couple of weeks but you should hear an immediate jump in sound quality if you run the whole system from it.

Martin,

Why 242V? I have started using Multiwave I think High Regulation sounds better. I do a cleanwave before I start listening. Just a quick question. What is the Phase Tune option and what value have you been using. I must admit not to have fully read the manual :D I wanted to get started. Now with regards an improvement with the system. Erm... I'm probably the most sceptical person around and I would say yes the soundstage has indeed increased. Instruments seems to have more "ooomph", and the timing seems to have improved as well. Micro-dynamics seems to be shining though as well.

Regards

A

The bigger the difference between input and output, the more the P10 has to correct. I feel comfortable with 242V and no more, achieving 0.1% THD out. No amount of adjustment will reduce that, and ultimately it starts to rise if I go too far. I left the phase alone on the same principle - it just raises THD if I go too far.

You must be joking! That's why I'm working on the Gales (http://theartofsound.net/forum/showthread.php?t=25059) :)

Mike, have you had a play with the settings, what did you opt for:scratch: I gave this one set to maximum regulation which seems to stabilise the output voltage to a near perfect 240v, its seems stable at 239.6v

Catching up late .....
Think I left the voltage to be set by the P10
Multiwave and High Regulation - which is what Martin T pointed out to me - makes a noticeable improvement
Now if it was just a few kilos lighter and I could turn that blue light off it would be perfect

Thanks. Good point - if you hadn't already told me !

My P5 doesn't seem to have a phase option in its setup - can you explain what it is and what it's supposed to do? The P5 has not been updated since I bought it, so once it's moved to my own house and can be connected to the internet, a firmware update may be required.

I had to do the firmware update to see that setting, Hugo. According to PS Audio, it should mostly be left alone unless you have a particularly severe load that messes with the output and then the phase can be adjusted in. I've left it alone.

It's worth doing the f/w update as it helps to prevent 'over-volt' warnings (which I've never seen).
