Summary: This is a solid, well built amplifier for a reasonable price. I bought the amp to drive my Klipsch in-wall sub (after falling over at the price of Klipsch's subwoofer amp). The sub is an 8 ohm load so it matches the specs of this amp in bridge mode well. Set up is a bit tedious as the manual can be rather cryptic and is very abbreviated. Also note, the support telephone number (in my manual version, at least) rings as disconnected.
Summary: I have an Integra reciever for my surround sound, but i also wanted to run my front highs and front wides speakers along with my fronts, surrounds, rears and center speakers. This AudioSource does the job. My man cave is now complete, the set up was easy and user friendly.
Summary: This amp is a solid performer with remarkably good construction and configuration options for the price paid. Even though I bought it to drive all of my outdoor speakers and didn't have high performance expectations beyond simply being able to supply a lot of power for multiple speakers and long wire runs, the quality of the sound at high output power was a very pleasant surprise.
Summary: I have been looking for an amplifier to drive two pairs of exterior speakers from the zone B output of my receiver, when I stumbled across the AMP 210. I took a chance and ordered it, figuring the worst that would happen would be to have to send it back. But it does exactly what I wanted, with far better sound reproduction than I expected from this very reasonably priced amp. My outdoor speakers have never come close to sounding as good as they do now.
