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.
Powering Revel M20's.
I need an integrated amp for these speakers. Since I just bought them, I don't have a ton to spend on an amplifier. I was thinking either the Musical Fidelity A300 or the A3? I'd prefer the A3 because it's cheaper, but I know I'll need the power of the A300. Also, I thought about the Audio Refinement. I've had this one, but I'm having trouble finding another one right now. What about older Creek separates? Any good? Thanks for your suggestions.
