Hi everyone, thanks again for all the input. I haven't decided ultimately on which solid state integrated to go with - so many great recommendations here!
In the meantime, I did happen to get my hands on a cheap Rega Brio-R, a late model made just before the most recent model was released, and I threw that into the system just to have something to listen to while I mulled over my other options.
I feel like I could start another thread on this topic - and maybe it's not for the Omega forum - but I'm just a little bit surprised by what I'm hearing. I've been a tube guy exclusively for more than a decade, and as I said I haven't owned a solid state amp since I had a Creek Evolution circa 2007, and an Odyssey for awhile after that. In my mind, SS amps are unfailingly harsh, brittle, edgy, bright, collapsed soundstage, non-holographic and all that. I avoid them for all those reasons. BUT this little Rega unit, as inexpensive and modest as it is, is somewhat surprising me. While it is not as holographic as the Line Magnetic, and a bit harder sounding, it is holding its own.
It's perplexing, in a way, and makes me wonder if the Line Magnetic amps don't truly embody the sonic characteristics of SET design (and don't get me wrong, I've loved my LM). Or is it just that some tube amplifiers nowadays are increasingly designed to emulate the desirable characteristics of solid state amps? And vice versa?
Anyway, makes me wonder what a truly high-class solid state amp can achieve....
