I had been using Bryston Equipment and tried out alot of Krell, but ultimately I decided to switch to the Musical Fidelity A3cr pre and power amps. These do not have the massive power of a 4B-ST or 7B-ST, but unless you are playing at huge volumes, you will not miss it. In every other way this pair is superb. Even my wife cannot believe the difference (and she was very skeptical). From soundstage to harmonic presenttion and naturalness to the tone these are beautiful sounding gear. If you want outside encouragement the power-amp is a Stereophile Recommended "Class A" and the pre is a Stereophile Recommended "Class B" and a reviewers choice for 2000 at SoundStage! Best of all the pair NEW is only $3000 and can often be found slightly used for $600 - $800 less. If your looking for new, I believe UpScale Audio is now selling them with a 30-day in home trial (no I don't work for them). I love these amps as you can see. I'm finally truly happy with my amp and pre.
Good Luck!
