Bryston or Pass Labs

To nekoaudio if l may ask why you preferred the bryston and the other listener preferred pass labs.

Pass without question.

The 350.8 us the very latest and gas several upgrades .it us a Fantastic amp. Several things to note Nelson Pass doesnot like using fuses for a good reason,because fuses suck and are bottlenecks. He uses a breaker that is  not a negative in the circuit 
He uses more mosfets on the outputs ,and several other improvements. One thing higher biasing into pure class-A
Almost 20wpc before it croses  over into class AB.
Meaning more then half of your music on normal listening 
Will sound even better being in pure class- A ,also depending how inneficient your Loudspeakers are  and doubles power into 4 ohms,and 2 .
The only amplifiers close to  this price class that may be a little more refined is the Vitus Amplifiers ,or Gryphon both from Denmark. 

The Pass amp is more than twice the cost of the Bryston. The Bryston is an 4B3 is an excellent amp.  I use the 6Bsst2 and it sounds outstanding with my Maggies. I haven't listened to the Pass amp so I wouldn't pass judgement. But , I believe you can reach a point of diminishing returns. 

Plus Bryston has a 20 year warranty!
