From what little experence I've had with AVR's and M22's, I can say you basically get what you pay for. At first, I tried a cheap 100wpc Sony I found off of Newegg for $150. It sounded good, except I wasn't getting any bass. Then I switched to an $800 Pioneer Elite with 110wpc. All I can say is WOW. It made all the difference in the world.
