I have a Behringer EP2500 that drives my m80 and I love the sound. The first time I cranked the juice up, I went to lower the bass of my sub but it was already off. Ten feet away from the speaker you could feel something on your skin when they were playing.
With the stock fans it sounds like a normal PC. Maybe someday I will replace them but when we listen to music or movies it never bothered us. The only thing is that I also need amplification for my other 5 speakers, so I'm currently searching for a multichannel (5) amplifier. I paid around 350-400$ canadian.
I did some test where my fronts were disconnected and I plugged a pair of QS8 on the amp. WOW, like getting new speakers. My wife told me in a matter of seconds that we needed an amp for the remaining speakers (4xQS8 + vp150)
