Mozvz, I responded earlier when you asked about the CJ ACT 2s synergy with the Pass. In a word, wonderful.
With the 100.5's on the Maggies now, I moved the 30.5 into my home office as an experiment. I've had the Cain and Cain Super Abbys in there for several years now and always got the best out of them with tube amps, especially SET's. The Abbys are a single driver/no crossover/fostex kind of speaker. Solid state made them sound hard and actually lose bass. Pass Labs and Mark at Renohifi both thought the 30.5 would pair nicely. I didn't think so. I was wrong. I'm listening to them now as I type. In three words: beautiful, relaxed and detailed. The XA30.5 is really a sweet amp.
Based on what you've said so far, I think you would be very happy with it.
Onemug,
Thank you for the updated information. I am still sifting through the choices with different scenarios in an equipment change/s.
It's also good to know the single ended connections are not any different then the balanced if I keep my CJ Act 2. Thanks Tvad..
