If you really want change get a pair of very powerful tube amps. And for those who don't like the chill, big tube amps do a great job of warming up your tootsies (toes) . P.S. Don't actually sit that close to you amps
I got a Mark Levinson 532H from my local dealer on a demo and the only thing that I could tell you is that this amp is very capable, it drive my dynaudio contour 5.4 with ease and with a sound that I have never hear before. Good luck Tango.
