I like my SMc Audio DNA 1, updated last year by Steve and Pat. As detailed, rich and natural sounding as I've ever heard. Not warm like tubes, but its never left me wanting them either. Never fatiguing. A different amp than the original McCormacks. Worth a look.
Many McIntosh amplifiers get you pretty close, I have had a few including MC7270, MC7300 and currently an MC352. Matching it a good McIntosh preamplifier is best. I have had a lot of the other brands mentioned in this thread but only quit switching gear with McIntosh, and they will outlast and retain better value than most.
