Pro audio amp vs. residential amp

I purchased a Crown XLS 1500 amp at Guitar Center (30 day money back) about 3 weeks ago.It has boat loads of clean power and is dynamic and detailed. I like it, and it cost $350
as they matched Amazons price. It's quiet, I don't hear the fan at all. Low noise floor,it's not a perfect amp, but it is very good. My 2 cents. Well worth the $350 for sure...

My experience has been the Crown XLS1500 sounds superb with all my speakers. I've found the amp to be extremely revealing and delicate with gobs of power. A full and totally open sound.
Very similar to my el34 based amp, but with much better grip on the bass. One thing I will say about the Crown, it needs about 400 hours,to totally open up.
It will drive 2 ohm loads with 775 watts on hand, so hard loads are a piece of cake. This amp give you a type of sound that should not be had for $350, it is an exception. As always of course YMMV!
