Powering Revel M20's.

The A300 is a great integrated unit for the M20's which I used to own awhile back. If its in your budget you wont be dissappointed at all. They are a great match together.

I ran mine with a PS Audio HCA2 (1100 used). Sounded great!

I'm using my M20's with a denon 3802 receiver (for now), sounds OK, but lacks bass control...

I haven't listened to any of the electronics you're thinking of. I've heard much said, but again, no first hand experience. What I do know first hand, is the M20s. I would look for the highest quality 100 watts I could find. If you don't mind lower volume levels, they will perform ok with 50watts. I ran mine, for months, with a YBA Integre integrated, and was very happy, for awhile. A chronic condition in this audiogame. The amp is (YBA per say) a very good match with the Revels. Be prepared! These speakers are very revealing, and will highlight inadequacies in your system. But then again; isn't this always the case with the embyonic stages of, what becomes a total upgrade. I started with the M20s and went backwards, to finally end with my source. Happy hunting..warren

Its hard to give advise when you don't name a budget. My suggestions would be depending on your musical taste the Proceed Amp5, Pass 5 channel, Conrad Johnson MF5600. There are others such as sunfire and rotel which are very good at a cheaper price.
