You don't even need an AVR, especially if space is a concern.
I have one of
these powering my M22's in our bedroom. Just RCA inputs, a volume knob, and outputs to the M22's.
While it can't provide house-party levels of volume, for normal listening volumes in an average sized room, the sound quality is incredible. In a PC setup, where you're sitting just a couple of feet from your M22's, the volume should be way more than ample.
And heck, you can even run the thing on 8 AA batteries - great for M22 tailgate parties. And you'd get to enjoy sexy class D amplification.
The only negative about it is that the build quality is about what you'd expect if you won it at a carnival.
Super cheap feeling. But I've had mine for almost two years now and it's still working perfectly, and the sound quality is great.
