Full-sounding SS amps (besides Pass)


Speaker interactions aside, what solid state amp brands/designers tend to have a fuller sound these days? Not necessarily warm or tubey per se, but fleshed out in the upper bass and harmonically complete in the midrange, as opposed to lean. E.g. an Australian ME Sound amp I have from a while back has this quality, without sounding overtly warm. 

Obvious candidates: Pass, Luxman. What else?

Cost no object, feel free to throw out one-liners. Think of it as a poll.  (Please don't answer tubes though, thanks. :D )

Many great suggestions here, but I'm surprised no one has mentioned Naim, especially the mighty NAP-500 with it's separate power supply.

Ayre and ARC are my favorites and I've been told Aesthetix is also good (something about the letter A?). I recently upgraded to an Ayre AX-5 Twenty. There are only a couple of separates I have heard that I thought were better.
I am so happy with Krell that I recently upgraded my 250s to their mono 575. Over 20 years ownership the 250 was matched with ss and tube preamps, and cone and electrostat speakers.
