I went with advice to look at US Acoustics amps for a budget system. I am very happy I did. It's very well made and has many features only found on pricier amps. Things like adjustable high and low-pass filters, adjustable gain settings. Many of the technical aspects have been well covered in another review better than I can do.

I'm using this amp as my main 4-channel driving a front component set and rear 2-ways. It provides plenty of clean power with no distortion. It far exceeds what I was hoping to be able to get at my budget level.
