Power Amp suggestion

What don’t you like about your amps and what aspects of the sound are you looking to improve?

I haven't logged in for a long while but I think the first response is a correct one.  First thing is to see if its really the amps you want to change. If you decide its the amps that seem to be lacking it is unlikely on the basis of power or quality.  Different solid state amps do sound differently.  I have a friend who went from very high end 2000 watt monoblocks to a different set. Neither were Swiss but every bit the caliber IMO. He loved the difference - but note its the difference.  Not that they are so much 'better'.  He found the new amps much more detailed and 'crisp'.  I inherited the old ones and they are quite wonderful, but a bit more laid back. Sometimes we just want a change.  Your best bet, if you decide this route, is the audition in your system. 

There is nothing specifically I don't like. II think they are pretty good and extremely well built. I have had them for 5+ years, since they were introduced. I have been told by some of my local equipment dealers that these  amps are perhaps due for an update and hence the request for suggestions. More detail, faster would be nice. More likely i just need a change.
