Threshold Stasis 3 Review from 1980

[Zentronics]

Leonard Feldman writes up this cherry of a review way back in 1980 for Audio Magazine. I thought it was entertaining on many levels...perhaps you will like it too? 40 years ago if you are counting...

Ahhhh.... The good old days.

These vintage PASS amplifiers are not driftwood found on a beach. They are children that came from good homes.

I operate this Stasis 3 on a pair of Infinity RS3b's and its low end is superb. After the amp has warmed up for about an hour it sounds superb.
I recently replaced its 40 year old filter caps with two 56.000 uF new ones which did improve the low end even further.
Relatively small but powerful and beautiful amplifier heartily recommended.

Great read! I like that it’s 70% topology/performance talk and 30% subjective listening review. That ratio is definitely in reverse nowadays.

I have and am in the process of restoring a Stasis II, which is cosmetically mint, but it has been modded over the years and is in need of a complete rebuild. It was driving a pair of Acoustat 2+2's and it sounded marvelous, until there was a power outage/glitch and caused something to let smoke out of one channel, it's been sitting now for 20 years, I have had it close to 30 years. I am looking forward to hearing it again.

Thanks for posting the review.

Cheers

Did I mention somewhere that I put together a simpler design for the front
end for the Stasis 2 and 3 and the following series?

I had someone whose front ends were trashed, and I took pity on him, plus it
was an opportunity to do the circuit with one less gain stage.

I also made some nice boards for it, and it worked great.

THAT is something I’d like to see

ok ok .... Mr. Nelson designed the amps but the preamps in those years out of pure curiosity who designed them?
Always Mr. Pass or Mr. Besnè?

Ahhhh.... The good old days.

Nelson, I have to say these are the good old days. With all of the F series amps, the pre amps, the H2 generator, crossovers and VFET amps you've given us, it doesn't get any better than this!!!
