I'm getting back around to purchasing myself a Christmas present in the form of an amplifier for home audio. A thread I made here a while back has me looking at two recommended amps:

CROWN XLS1000 found HERE

or

QSC GX3 found HERE

The Crown is Class D and the QSC is Class B. I've researched the difference between the Class B/D and found a lot of techie stuff that I don't really understand. Does anybody have an simple explanation and/or recommendation based on this?

I really like the weight of the Crown - 9 lbs vs. 27 lbs. I also like the warranty of the QSC - 6 years vs 3 years. Other issues I read about are fan noise but appears to have been corrected.

I appreciate any feedback

Thanks!
