PS Audio's new "Gain Cell" Amplifiers . . .


just announced today.

Is it possible that it is the real deal?

A 500/1000 (8/4) wpc integrated amp???

Sounds like the "analog module" of 1970's Audio Research fame. More "perfect" amplification? Seems like many of the module type circuits had an opamp inside they didn't want you to see.
Pmotz-
It sounds like the unit is directly controlling the gain on the input signal. I believe a volume pot is independent of the input signal gain which is usually fixed.

I'm sure someone has thought of this before and there are probably inherent problems to this approach. Can you say "hype"?
I remember the Quatre Gain Cell and it was "the" bass amp for Fried Transmission Lines. I remember it being very powerful but sounded much like the GAS (great american sound) amps of the day. Not too refined. PS Audio has in my experience and recollection been famous for its bass reproduction. I had the original PS Audio Phono stage and separate power supply and the bass was suberb. I imagine that if PS got a hold of the gain cell technology that they have done something marvelous with it.
The Gain Cell design of PS Audio and that of Quatre/QMI are unrelated. The marketing pitch for the Quatre Gain Cell implied a complimentary symmetrical channel design that was supposed to cancel out non-linearities.

I spoke recently to Dave Gore, designer of the Quatre/QMI Gain Cell series. He commented that he did not claim to invent the term Gain Cell and felt it rather generic.

Whatever happened to Dave Gore?

I used to work for Quatre.

The Gain Cell amp we made had terrific bass - and was highly regard in it's day. I wouldn't call it rough. In a showdown (Audio Critic) against Audio Research, Threshold, GAS and quite a few others - it came out as the winner. More liquid-sounding than the GAS.

It is still a pretty good amp. Still has great bass. And yes, it did have stability problems. Had a proclivity for going into DC offset and lunching a woofer.
