Musical Fidelity A300cr.

If you are talking about the A300 integrated, I had one for the 30 day trial from Audio Advisor and really liked it. It was not rolled off in the highs to my ears (like some reviews have said), but actually very forward. The tone was superb (horns sounded great as did piano) and the detail exceptional. I did not think it was especially powerful but for $1500.00 was a steal.
Try the Creek integrated too.
My associated equipment was Magnepan 1.6, Rega CD 2000, Blue Heaven wire and IC throughout.
By the way, I ended up going with Rogue tube gear that cost 4 times as much. For $1500 I would have bought the A300 (the Creek was not out yet)

No, I'm referring to the power amp, NOT the integrated.

Just my 2 cents. I also am not referring to the A300CR but to my A3CR and Audio Research LS-12 combo I use in a small second system. Simply much more fluid, musical sound than you would ever expect from solid state. Incredible value.

I realized that you are talking about the new power amp which I have not yet heard. My comments were about the A300 integrated. Sorry. The new amp looks great though.
