Lissnr, I'm glad to hear about another Diva owner using tubes. I think Apogees and tubes are the most magical combination possible, yet so many people parrot the claim that you have to use Krells with Apogees.
Tomb11, One thing I've noticed with the Divas (albeit driven by 1000 watts of tubes) is that they don't give you the usual cues of excessive loudness that other speakers do. Most speakers will sound LOUD because of "cone cry", non-linear distortion products and thermal effects on magnetics (as well as amp clipping). Many times with the Divas, I've realized just how loud they are playing as the volume level has crept up and up. Someone will walk into the room and have to shout to me over the volume levels. That's not necessarily a good thing for my ears. The Divas keep their composure and continue to sound pure and clean, which can fool you into thinking they are not as loud as they really are. Jason Bloom claimed that the last version of the Divas with the stronger magnets could hit 118 dB SPL with 100 watts per channel. I am sure that I have momentarily gotten into the 120s of dBs, but I do not need, nor want, to go there out of concern for saving what's left of my hearing. At reasonable or slightly loud levels the dynamic punch and purity can be really pretty astounding.
