Finally decided to go separates and get a power amp to drive front stage in my 5.1ch home theater. My speakers are Ascend Sierra-1NrT and currently powered by the Denon 4311ci. I crossover them with a Rythmik F12 subwoofer at 100hz right now.\n\nLooking at a few models. Hope folks here can advise.\n1. Marantz MM7025\n2. Parasound Halo A23 (can get for $600)\n3. Parasound HCA 1500A (can get for $375)\n4. Krell kav 250a 3 channel ($1,300) \nAfter I power the L\/R, next step will be to get a 1ch or 2ch and power the center speaker, but I figure if I free up the load of the 2 channels, more power from Receiver will go to center.
