In Reply to: RE: CCS study in depth, what do you think this approach posted by Eric Chan on April 24, 2024 at 23:34:14
That post by Naz is just more evidence of the fallacy of attaching SS devices to the signal paths of vacuum tube circuitry. Anyone who has seriously compared the old school sound of vintage '60s gear to contemporary amplifiers knows the risk.
Follow Ups:
He wrote to me some years ago that resistor in place of CCS actually sounded surprisingly good. He mostly used CCs in series with output transformers.
Well, JFET and MOSFET supposedly better than bipolar, could also make fantastic zero NFB amp
I also own Ayre top gear amp, such as K1xe, VX5 twenty, smooth and absolutely transparent, delicacy and subtle signal handling even better than triode amp due to no coupling cap and transformer
Maybe we think of the cooperation by tube and FET could achieve something more, no need to be reluctant to SS because nowadays the music source most come from DAC which is made of SS
I find "old school sound of vintage '60s gear" interesting and nostalgic but I wouldn't want to listen to it now days. Too bloated, fat, slow and muddy.
I like clean and clear and fast and detailed and that's what I get from my tubes.
Way better than anything built in the 60's.

There's nothing bloated or muddy about a Citation V. And it has none of the "scritch" or annoying sibilance-like distortion I hear during extended listening with most SS gear. The last thing I want to do is introduce those characteristics into high quality tube gear that is otherwise pristine and transparent. There's no benefit to this that can't be accomplished by other means, and it simply isn't worth the risk.
Don't have any of that stuff going on.
Given the way you speak of it, you must have tried using some sort of SS and had bad results.

Friend, I would not hurt thee for the world...but thou art standing where I am about to shoot.
Fair enough. I can't stand SS amps for mids and highs (the upper ordered HD makes them sound bad). I have a Cit 5 but honestly I haven't really listened to it (I should sell it). I own one Cit 2 and have owned two others. I sold them. I can't stand the way they sound (all those pentodes with their upper ordered HD and all that feedback trying to fix it). That amp ends up sounding like a SS amp.
I built a different amp (different front end circuit using triodes and put the output tubes in triode mode) with the Cit 2 I kept. My cousin uses it. It doesn't sound bad. The output transformers are outstanding. I have a spare pair of Cit 2 output transformers. I built a all triode PP 300B amp using them. That amp sounded good but I like DHT SE better.

It may sound rough and can't image for crap and it's an effing B class stage but damn it, it's fun as hell on 96db FR speakers.
