For those of you who have been wanting some positive feedback on this combination. All I can say is WOW!!! The sound is so clean and so much detail compared to my old Bryston amp/pre amp (3BST-BP20) The one thing I can say is that my Magnepan 1.6QR absolutely sound like brand new speakers and the soundstage is so well balanced. The folks at Pass Labs are great to deal with and I am very pleased with my system. My main music is Classical and Jazz with some modern POP, older Rock. Hope this helps solve some curiosity.

System consists
Nordost Speaker, digital audio connection
Pass Labs AMP
ARC LS 17 tube preamp
Audiolab MDAC
Wadia Itransport
Oppo BDP103
Magnepan 1.6QR
Martin Logan Abyss Subwoofer
Nice! Birdie.

I concur, that Pass is something special indeed. Keep us posted as you break-in these 2 pieces and happy listening!
Additionally, the ARC Ref3 and Ref5 SE are a nice match w/ Bryston power amps on Wilson speakers. I have heard this combo many times. Happy Listening!
