Pass x250.5 or Bryston 14Bsst² ?

Does anyone have experience with both the Pass x.5 series and the Bryston sst² series? If so, which would you recommend? I think I've narrowed my choices down to these 2 amps, though I can't decide between the two. I have heard both, but not for a long enough audition to really make a decision.

Speakers are Von Schweikert Unifield 3
I've had Bryston 4BSST2 and now own Pass XA30.5. Pass is at another level in terms of sonic quality. 4BSST2 may drive difficult load better but I use 91db 8ohm speakers, so I would not know.
Yeah, kind of a tough call. The 14Bsst2 is one of Bryston's best and the Pass Labs is superb all the way around. It's ultimately your choice.
