Davemitchell- Perhaps Mr. Aczel is a re-incarnation of Mr. Hirsch? If these listeners can be satisfied with the Behringer equipment in their listening rooms, let them enjoy their savings. By the way SameDayMusic.com offers the amp for $199.00(free shipping), and they have most excellent customer service, and a satisfaction guarantee. I've ordered a lot of Behringer gear for the stingier/less critical of my pro-sound clients from them. I use a DEQ2496 to check my listening room's response now and then(the 61 band RTA is great). I'd never have it in the signal path though, even as a pink noise source(if it went, it might take something valuable with it). OH- musiciansfriend.com has the A500 on sale for $180.00(free shipping). Their customer service is pretty good too.
The Best Amp for the Price of Dirt
The Berringer a 500 Reference Amp that can be purchased on Musican's Friend web site for 194.00( each) to your house in the US of A w/ a 2 year warranty is a KILLER. I have several amps and these are scarey. Granted they were designed overseas & built in China... However, they are 19lbs GIANTS . Don't take my word go to the "Audio Critic" web site for a full review. This is my one an only give-away . Use it or loose it. Best to 'All
