Feature:
Turn it on and forget about it!

Quality:
So far--so good. We've used four of them fot the last 6 months and had NO problems.

Value:
Good value for the money

Desirability:
This product met our particular needs in the price range and was suitable for the type of music that we play.

Sound:
Sound quality is good. We only use this product live. We use 4 of these amps with 16 JBL SR4726 speaker cabinets (four per amp @ 4Ohms) and the sound quality is superb. Give them plenty of electric and don't over drive the system. Any Amplifier will reproduce the sound efficiently if the system is set up properly. Don't ask it to do more than it is capable of doing. Our Crown power Amps seem to work much better on the low end though.

Support:
dont know

Overall:
hopefully we will keep these amps until we wear them out.We compared this product to Crown Amps(probably not a real fair assesment), but dollar for dollar we feel this product served our needs and was an affordable alternative. The fans are a little noisy, but tolerable.
