I picked up a used Harman Kardon AVR 220 for $100. I use it as a 2 channel receiver for a pair of M22Tis with a little Velodyne DSP sub. I was very surprised at the excellent sound quality that this HK puts out. Sounds great with the M22s!
I have a 2 channel in the exercise room, an Integra DTM 5.3 stereo receiver which I found on Craigslist ($60 no volume knob, found a knob), a pair of Dahlquist M905s and a Velodyne DSP subwoofer. This is the best sounding system in my house.
Find a good used receiver, save a boat load of money, get terrific sound quality and be happy.
M22s are terrific speakers when assisted by a good, clean, fast sub.
I ordered a pair of M100 V4s, cherry B stock (the current listing should say "sold") and an Odyssey Khartago amplifier. I hope this system sounds as good as the $120 system in my work out room (not counting subwoofer).
