Hi again cacatalysis. I actually did use different preamps for the Staxes for a while, and they did transform the sound, but there was always some sort of a wall or fogginess there, even with the best preamps, so I gave up on those (even passive preamps
like Placettes had a curtain-like affect). But the Staxes (Omegas with the 007t amp) didn't really need any warming up, as they were maybe the least fatiguing phones I ever had (sort of miss them...). I used an Accuphase DP75V cdp for them and the sound was
easygoing and musical and well defined, if not very dramatic or spacious. They were very un-speakerlike, but nice on their own terms, very intimate and close-up, like first-row listening. I liked them much better than the HD650s I had at the time,
which I could never warm up to, and found them claustrophobic.
The Pinnacle with the right 6ns7 tube deals well with glare. (Thank goodness there is just one tube to roll, a real advantage to the Pinnacle if you like tube rolling. The PX4 tubes are really not replaceable.)
The B52 has a reputation of being warm, but from a glare perspective, it is about the same as the Pinnacle, even with Mullard tubes. (The B52 is a fine amp too, but that's too deep a subject for now.)
The Rudistor is about the warmest of the solid state amps I have heard, and for some reason the Rudistor seems to match very well with certain headphones, but not with others, with taming shrill highs part of the goodness.
(I really like the Rudistor with Denons [D7000s] and Senn HD800s. Beyer T1s can scream a bit with the Rudistor.)
Just to digress, I think the particular amps seem to mate well with particular phones for whatever mysterious reason.
But after all this thrashing around and experimenting, I've settled on Audezes for now with the Pinnacle for letting me forget about gear and just listening to music for it's own sake.
(I also listen to speakers, those little-known Lahave monitors in my avatar, using the Pinnacle as a really state-of-the-art preamp. Just IMHO, those little 30-pound speakers sound as nice and coherent overall as the megabuck monitors I heard at shows, like TADs for instance.)
