Audio inovations l1?

[alfie2902]

Huh!... say what?

Cathode follower perchance?

You might well be right Mike, I haven't got a clue tbh!

But was told that they rejected the cathode follower configuration for an anode follower circuit as it sounded better, but it all means nothing to me

[Mike]

Ahhh... hang on!. I thought for a min that it's something I've never heard of. But I have!

Only I heard it referred to as 'plate' follower! It's the same thing!

I've no experience of it, so it didn't ring a bell, sorry.

here's my L1 wot I bought new back then, its modified with FranklandCapacitors and a ricardoStepped attenuator.....I originally used it in a second system and it provided good service - it replaced a Rose RV23 which I regret selling.

The L1 is a nice basic sounding pre, nothing a Croft wont be scared of eh Dave ? it is flat and shiny compared to my slushy SP8 and Sp10





the headphones are AT electrets in case anyone is not interested

Please note the advanced high-end CABLELOOM

No doubt these mods gave the L1 an Absolute Flat Response..... (Chris)FranklandCapacitors and a Ricardo (whatsisname) Absolute SoundsStepped thing...

alright I'll get me coat....

Why not get in touch with Guy at Puresound (that's his online monika). There was a thread on PF about these IIRC and he designed them (again, IIRC).

He may be able to recommend some sensible updates to it and hifi Dave tells me he's a good guy to deal with..

Yes Guy is one of the good guys. I have known him for years...more than I care to remember, though until he had Puresound I had not spoken to him in quite awhile; since the Audio innovations days (except for meeting him at the odd audio show) Edit and on AOS recently of course

Here's a link to the thread on PFM. Quite a good read.

I also read somewhwere of Guy commenting on hearing an L1 recently that had been rebuilt point to point wired & was quite impressed IIRC.

bigmoog how much improvement did modding the L1 with Frankland Capacitors and a Ricardo Stepped attenuator make?

I bought the L1 as a stepping stone until I've sold my Expo's, but it's doing a better job than I expected so who knows what will happen, Just wish I had some basic electronics knowledge & better soldering skills!

Cheers, alfie

EDIT; Just re-read the thread I linked & the point to point rewired comment is in the same thread

well, It has superb foot tappability and pure Rankinian/Collomsish PRAT aligned with awesome detail, huge enveloping soundstage,harmonic thoroughness and extended highs.....also the noise floor is so low, one can hear what type of velour the chairs of Carnegie Hall are made from.


siriusly , I modded the L1 with a TDK stepped attenuator and had new caps fitted, so now it sounds slightly 'fatter' and less 'shiny' if you know wot me means.....I also changed the stock ECC82 for a NOS Kremlin Cryo-Tube

Thanks for that bigmoog!

Yes I understand what you mean by 'Shiny'! My WAD KEL84 is the one input version with a volume pot & If I run a source straight into the KEL it sounds a little 'Fatter' But the L1 seems to add a little more detail & gives me a little more gain for my phono stage

Alfie,the pre is probably driving the amp better than the source is capable of.It may also provide better impedance matching.As for tweaking it,look no further than Hi-Fi Collective for some boutique capacitors and a stepped attenuator at good prices.The best caps I've heard are the SCR teflons,but these are seriously expensive.A very cheap cap are the Sonique (made by Clarity Cap) range sold by WD.These are stonking value for money at less than a fiver each.You have several in your KEL!
