Preface this by saying "IMHO"
Krell - not musical, analytical, dynamic, great bass slam
Rowland - musical and smooth, fantastic soundstaging, full bass, recreates the live event
These are two totally different beasts even though they are both solid state. I would imagine the change from the Krell to the Rowland (also factoring in your upstream electronics) is that you now are having a little less dynamics and bass slam, but much more smoothness and musicality (which is what I prefer). If you are looking for a little more of the Krell 'slam' I would suggest selling your Cary tube Cd player for a Wadia, or other high - end non tubed CD player. Too much tubes and smoothness is sometimes too much!
