I used one for a while and thought it sounded great. The only things I didn't like is that it didn't have RCA inputs and the speaker outputs were Speakon connectors, and the fan noise was better than .
For inexpensive pro amps the Behringer a500 has no fan and has RCA inputs and normal 5 way binding posts for speaker connection.
I sold my Tapco when I got a deal on 7 channel amp. I'm selling my Behringer if you're interested.
