Hi Andrew, I have a plan for solving the problem you mentioned. I am on it.

You forgot to say cunning plan

, because it make me relax, details, no harsh, no fatique... and LC it's have been past nine hours now

Mikelm should read this

And with 40V regulated it will sound better

We need more photos with your amp at work, don't we?

Hi Salas, we do.

Naf, show us the amp-porns.

I experienced this 10 years ago. I couldn't forget the amp and couldn't understand why my (supposed to be better) later amps couldn't do the same .

Only not long time ago I know that it was a CFB amp. Only opamp was used for the input. The opamp was better than 5534, but the lousy sound of opamp was there (Sorry to those who cannot hear the sound of opamp )

The solution is supposed to be "on the way" . Keep putting pressure on L.C. ;-)

It was the Mark Alexander's one ?
About Op amps sound, just try some CFB ones :-)
I'm not able to feel any change between 4 of them in serial with several configuration (inverting/non inverting, 10X gain or 1) and a strait wire in instant comparison.

It is out of topic, but i had all my life a problem with the analog mixing desks: The mixing bus is the - input of an opamp. So, more you plug tracks " in the air", more the gain of the amp increase to keep each track at the same level, and more the sound is ' lousy'... until i changed-them for C.F.B. ones...

Yeah I know that for everyone else, the amp was about CFB, but for me it was about IGBT I knew anything about CFB amp was only after the SSA (honestly, I followed the thread because of the IGBT thing). When I looked back, I realized that many of the good circuits that I prefer were CFB. I also liked to choose a small FB resistance, VFB or CFB.

Stochino amp for me was about high slew rate amp. Then I started to look at slew rate parameter in opamps. Coincidentally most CFB amps also have high slew rate.

And the AD opamps are I think the best I have heard. But I couldn't accept any preamp. Preferred discrete. But lately I can accept tube preamp (as part of the DAC I/V) after extra work had been done with the power supply.

I am sory for those who (think they) can.
