Is there a solid state power amp that truely has the magic of a tube amplifier?
IMHO, no.
There are SS amps that have qualities that you may value in a tube amp, while possessing other qualities (and weaknesses) of their own.
The only time I've heard VAC was at RMAF and that was very impressive, as I recall. I honestly don't know if was the same amp you have. If you really love that sound, I'm with Fplanner2010: try to stick with it for a while rather than selling something you'll regret losing.
That said, I was hooked on tubes for many years and didn't think I'd ever go back to SS. The Modwright KWA 150 was the amp that did it for me. That amp possesses the midrange magic of tubes while adding the extension and power of SS. I'd put it on your short list. Disclaimer: Dan Wright is a client - I do his photography and graphic design. I would certainly look into the usual suspects too in the high-achiever SS club led off by Pass. I have also enjoyed hearing Ayre as well as Edge. I don't know that any of those have really brought tubes to mind on listening, as the KWA does for me, but I wouldn't kick'em out of bed either. I do prefer the elements of midrange palpability and soundstage prowess and the KWA excels there.....but again, I haven't heard any SS amps that sound just like a tube amp in every which way. Then again, there are so many amps and so little time - mine is only one opinion with very limited exposure to what you are asking about. There are all kinds of SS amps that strive for that quality and I certainly haven't heard a tiny fraction of what is out there. The VAC you have will undoubtedly leave big shoes to fill if you give it up. If you can do some comparisons without giving up your current amp, I would go that route.
