Bryston or Pass Labs


Looking at the bryston 4b3 or the pass labs x-350.8 anyone has heard the two and which is the better performer?

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. 
Why are you limiting yourself to those two amp? There are more contenders out there to choose from.
