    4 Star Rating Mike From Long Island
    This amp is great for the money! The sound is clean with little distortion. The amp functions perfectly and has not given me any issues. I am running 2x PRS-720s (6.5 components) in the front and 6.5 D series, both Pioneer. The sound is detailed, the only thing I would be critical about would be that the mids seem a little reticent. And this amp puts out what it gets so if you have a crappy sounding recording you are going to get crap out. Some amps are a little rounded and will make music sound better even if its a bad recording. Nice soundstage too! Overall a great purchase and good for those looking for a good start.
