I'm about to order an AMC 2N100-3 (3 x 150w/ch.) power amp. I'll be adding this to my HK 510 to power my fronts and let the receiver power the surrounds. Then eventually I would add another 2N100-3 for the rears. I have a rear center that runs through my old Pro-logic decoder and hopefully adding an amp to the decoder for the 6th channel would work. I was wondering if there's anyone who could share some info or experience with this amp. I'm deciding with the AMC because of the price and specs. I'm holding off the order until I get enough info about the unit. And I thought this would be the place. The other 3-channel amps I'm considering are B&K ST3140 (3 x 140w/ch) and Denon POA-8300 (3 x 120w/ch). Other notables are B&K AV6000 (6 x 125w/ch) and Marantz MA-6100 (monoblock x 125w). The Denon and Marantz are both THX Ultra certified. I would appreciate your input. Thanks.
