Not yet, but the next time I do a pro install I will be. I've used quite a few Behringer pieces in my sound tech work(especially the last 10 years). For the money- you can't beat the stuff. Every install I do, I insist on a DEQ 2496 to curve the room response(after whatever treatments are done). With this return policy, it's hard to go wrong on the A500: (http://www.samedaymusic.com/returns) If you should happen to not like the sound, just let them know it wasn't up to your standards. I've dealt with Same Day quite a few times, and never got a hassle from them on a return. I believe some of the guys on this thread tried it(at least the thread starter did): (http://forum.audiogon.com/cgi-bin/fr.pl?aamps&1170999828) You might e-mail him, and inquire.
