I heard the same system with the Diablo 300 and the SF Serafinos. I'm wowed by the sound of the Serafinos, so much so that I "invested" in a pair. I sat there for a good period of time listening to several tracks that I listened to at home the night before. I know, it would be comparing apples to oranges, but I thought the Diablo system lacked the warmth & mid-range of my McIntosh tubes at home. That was the first thing the consultant commented on to me when I told him my impression - difference between SS & tubes. Don't get me wrong. If a Diablo showed up at my doorstep, I wouldn't stamp it "return to sender". But, I will have to go back and listen again based on the feedback here.
Happy to say I don't know what the Class D argument is about, and don't think I want to know given the tension around it.
