Good luck with your request from PE...

I asked them about the damping factor and the slew rate and got nothing. They explained that it didn't matter and that was the end of my search for that info. For the money, my guess would be a DF of about 30 or 40 but we'll never know. The examples of amps I sited may be a little pricey but there are some others I couldn't think of their names of the top of my head. Some more moderately priced(in the $200-$300 range) are American DJ, Gemini, Pyle, and Samson. As you said, you mostly get what you pay for. As I was told by an old friend(remember Steve W) these amps are built for commercial use and will take quite alot of punishment ie. last a long time. Look for something in a DF of 100 or more and a SN ratio of 95db or better as well as mono(bridge) capability and you'll do alright. Search for Pro Sound and there's alot of retailers out there.

I agree about the convenience of plates as well as the bang for the buck, but don't believe you have to mount the "DJ amp" in the rack. Yopu can conceil it just about anywhere in the room and run your long cables as low level RCA for less cost. Besides, when you start talking about that 500wt or the 1000wt amp from PE, you're talking about the same or more money as with the others.

Just something to think about.
