So I am looking to putting a little more power into the Rti A7 front speakers I have had for awhile now. I have seen on my forums that it would be benificial to bi-amp them. Could anyone recommend any amps for my situation? My current setup:
7.2
Fronts: Pair of Rti a7s
Sides: Pair of Tsi 200s
Backs: Pair of Fxi a6
Center: Csi a6
Subs: Pair of BIC America V-1220 12-inch 430-Watt down firing
Receiver: Denon 3313(125 Watts per channel)

    Forget bi-amping. Just get a quality 3-channel amp for your mains and center and you're good to go. If you're looking for specific recommendations, what's your budget?
    Equipment list:
    Onkyo TX-NR3010 9.2 AVR
    Emotiva XPA-3 amp
    Polk RTi70 mains, CSi40 center, RTi38 surrounds, RTi28 rears and heights
    SVS 20-39CS+ subwoofer powered by Crown XLS1500
    Oppo BDP-93 Blu-ray player
    DarbeeVision DVP5000 video processor
    Epson 8500UB 1080p projector

    Your subwoofers are doing all the heavy lifting power wise, I see no reason to even add an amp untill you move up to harder to drive speakers. Sure, some benefits will be had by adding an amp, but may not be the bang you had in mind.

    +1 Get a 3-5 channel amp of at least 200wpc @ 8ohms sit back and enjoy. This will allow your speakers to operate to their full potential as well as enough power to manage just about any speakers you might get in the future.
    Marantz AV-7705 PrePro, Classé 5 channel 200wpc Amp, Oppo 103 BluRay, Rotel RCD-1072 CDP, Sony XBR-49X800E TV, Polk S60 Main Speakers, Polk ES30 Center Channel, Polk S15 Surround Speakers SVS SB12-NSD x2

    I tried bi-amping my A9's (passively) just to see for myself if there was a difference. I also tried by-wiring them with dual 12 AWG wire. I personally noticed absolutely no audible difference at any volume level. One amp channel per spx connected with one 12 AWG wire is good for me. I cannot speak for active bi-amping.
    Full 8.2 with:
    Onkyo TX-NR818
    Emotiva XPA-3

    Behringer EPQ2000 w/quietfan mod
