Hi, I'm looking for some more advice on some used amps to power the fronts and center of my full NHT setup. I'll be using a receiver to power the surrounds/rears until I can afford a second amp. I've been looking at getting two HK Signature 2.1 amps, but recently found a parasound HCA-806A 6ch amp also. Here's my setup: Fronts: 2.5i Center: Super One (Will eventually be the AC-2) Surrounds: Super Two Rears: Super One The 2.5i's are 6ohm and the rest are 8ohm. Amps I'm looking at: HK Signature 2.1 ([email protected], [email protected]) all driven Parasound HCA-806A ([email protected], [email protected]) all driven, and channels 3/4 and 5/6 can be bridged into 180W. They say bridging should be only into 8ohm speakers. I'll probably be getting an outlaw 1050 or denon 2802 receiver to hold me over until I can afford the second amp and an outlaw 950 pre/pro. I'm guessing the Sig 2.1 would be about 125W/ch at 6ohm and the 806-A would be about 100W/ch at 6ohm for my fronts. With the Sig 2.1 I was going to remove the straps and bi-amp my fronts and use the 5th channel for my center. With the 806A it looks like I could bi-amp my fronts with channels 1/2 and 3/4, then bridge 5/6 into 180W for the center. Would I be better off trying to get two of the Sig 2.1's? Or would the 806A be fine to start with, then move it later to power my L/R surrounds on the two 180W bridged channels and run two rear centers off the left over 80W channels? Any thoughts would be appreciated. Thanks!
