Hi DrM,Thanks for the review - I enjoyed it, and always enjoy any personal opinion in this forum.
I especially noted your comments on reproduction of large orchestral recordings. That really IS a huge stumbling block for most systems. I've spent about 4 years now trying to get my tube-based system to do that as well as my previous standard, a solid-state sytem with very inefficient speakers.
That particular SS amp, a Michael Yee Audio 100W/ch bipolar design, had a rare ability to maintain all the separate threads of orchestration in the most demanding passages, although the recording and source could also be at fault here. I also sensed compression distortion, where the amp was willing but the speakers weak - I could never really get to truly realistic volumes without a sense of reluctance somewhere in the system.
I found that only after getting speakers of > 96dB/W with minimal or no crossover, is my system beginning to approach and exceed that standard. I have recently suspected that much of the problem is simply due to sheer distortion at increasing power in SE amps, exacerbated by passive crossover/driver impedance variation and reactances. The tube amp pretty much comes apart, sonically, when the going gets tough.
Now, with speakers approaching 100dB/W, my 3W 6A3 amp is rarely straining, or exhibiting audible distortion, until I go crazy with the volume control. Up to near pain threshold, I can track very delicate sounds that can be distinguished from louder sections in dense orchestration.
Has all this effort been worthwhile? The old system really was VERY good in most ways. But now, my stuff is nearly all made and modifiesd by my own hands, and generally sounds at least pretty good, and THAT is the real reward.
OK, if I had > 105dB/W speakers, like the Oris........
