I have a pair of Pass XA60.8’s, and I am driving Dynaudio Confidence 20’s. Preamp is a Prima Luna EVO 400. They sound amazing! I use a Dynaudio Sub 6 as well, but I turn it off when listening to jazz/vocals. Previously I had a pair of Harbeth Monitors 40.2. They also sounded amazing, but I moved into a smaller listening room. So, I got the Confidence 20’s.
Honestly, I don’t think there is a speaker out there that wouldn’t sound good with Pass Labs amps. Just match the power with the load, and you should be good to go!
