Ok, I am looking for online resources for GOOD prices on power amplifiers. I am looking for a Sherbourn 5/1500 NOT the A model, the original (hey, its a good amp...just discontinued) anyone know any resources that I might check? Ok, or if I cannot find another sherbourn, is Outlaw any good? They have good prices, but gee...i'm not sure. I am going to need 12 channels of power, I have one five channel, so, I will need to obtain another five channel and a two channel, but I want them to be of the EXACT same model type, other wise there will be a difference in the sound I fear, and besides, they are asking a little too much for the new 5/1500A - which, I would not be able to use to its extent anyways, I don't have XLR outputs (Yamaha RX-V1). And I thought they made 3 channel power amps, am I wrong? Or for you home theater guru's out there that have been doing this for longer then me, would bi-wiring the back channels make a difference? I plan on using Paradigm Studio Reference 20's (3 of them) for the back channels...or would bi-wiring JUST the front channels (Main L, R, Center) be more beneficial - sorry bad spelling, in a hurry...anyways...what do you guys suggest...I am in serious need of help, because I don't know which way to go, i've heard the difference in bi-wiring the mains, and it makes a considerable difference, however, I just want to know, with the way DD/DD-ES/DD-EX works, would there be a gain from this?
