I just purchased this amp to power the lower end of my Polk Audio RTi12 speakers. I am using Polk Audio Monitor 70s on the rear channel in combination with a Klipsch KV-1 center speaker and a Klipsch KVW-150 subwoofer. I have my system set up for home theater surround sound, but I listen to mainly music. My TV is rarely on other than to watch a good concert on Blue Ray. I had been running My Polk Audio RTi12s from my Denon AVR2807 and they sounded pretty good, but every review I read on them said they would sound best bi-amped, so I had to give it a shot. I choose the Parasound 2250 because of the rave reviews I read about this amp. This amp's power rating is way over rated. My Denon puts out 110 watts per channel into 8 ohms. The Parasound 2250 is rated at 250 watts into 8 ohms. I assumed that the 250 watts through my bass speakers would be a good match with the Denon pumping 110 watts through the upper end speakers. Well, the truth is, with the gain turned all the way up on the Parasound and the Denon set at almost maximum volume, the Parasound 2250 just about holds it's own. The bass was very clean and crisp. The amp does have the quality that all the other reviews I read claimed, but I was disappointed with the power output. I know bass speakers eat up more power than midrange and tweeters, but I was sure that 250 watts through the lower end would have provided a much stronger bass then they did. I also have to say that the speakers do sound better bi-amped. I just wish I was able to boost the bass a little farther than the Parasound 2250 amp does. I'm not sure if the Parasound is over rating their output or if Denon is surpassing its rated output. Overall, it's a very nice addition to my system, but lacked the punch I was hoping for. Now I'm toying with the idea of buying a second one and bridging them to get 700 watt output from them and using them separately for each speaker. After all, as I said earlier, it is a great sounding amplifier..
