Well, they have "gain" in the title, and in the photo of the back of the board one can see where a chip with legs seems to be attached. Since the rest is surface mount I guess that's about all we know.

Looks to me like someone else has discovered how good chips can sound!

:devilr:

I think these soldered pins are actually from a socket that connects the visible PCB to other PCB above it

The text and the specs make me think about some high quality VCA chips connected in series to achieve that gain range and a DC servo for DC compensation

And a lot of pseudo-science marketing...

They say P.T. Barnum put a sign reading "EGRESS" over a door in his early shows. Folks bought into that one too.

Looks like the world's biggest op-amp, but not so flexible.

I must say that their marketing is very good though. After reading the article I almost wanted to experience Pure Resolution™ myself!

My WAG from the typical McGowan market-speak hyperbole -
a TI THS41x1 fully differential ic (or TI's audio specific TPAwhatever) surrounded by a Wolfson WM8816 for 'non-attenuating' volume control.

Revolutionary? Hardly. But it does seem a nice approach.

'the culmination of 25 years of work...'
Possibly, but not work done by PS Audio.

Pmkap,

Sounds like a product to reverse engineer......................;)

Let 'em try to patent it......
 
Anyone here read John Curl's post on how some guy that he showed the fully-complimentary differential input stage tried to patent it?

Yeah........audio is full of.............(fill in the blanks).

Yeah, they ripped off the name. Quatre used "Gain Cell" for a line of amplifiers and preamplifiers back in the 1970s.
