hi guys, im planning on buying a Yamaha RXV671 and RTIA7 to start my home theater setup and am wondering if i should go with the bi amp setup. Would the Yamaha be too under power for the speakers? Also do i still need a outboard amp if i hook them up as bi amp? thx

    Forget the Biamping, it's way over rated. I honestly believe the rxv671 is underpowered for those A7's but a receiver with preouts is a must.

    There are certain receivers where bi-amping makes sense, and other's where it doesn't. I don't think the yammy will give you any more juice bi-amped, so no, I don't think it's worth your while, but you are more than welcome to find out for yourself ;-)

    If anything else it cuts your power down because your powering a 7.1 system instead of a 5.1

    Also, I would go in another direction receiver-wise. I started with a Yamaha RX-v663 when I first bought my RTi A7s and it made an already bright speaker a little brighter. Bi-amping using the Yamaha itself also didn't make much difference (same power supply after all).

    Getting a Pioneer SC series receiver will get you a better experience and about 75% there. Getting any receiver w/ pre-outs and the features you want (Denon, Onkyo, Pioneer, RX-A series Yamahas, etc.) and a nice multi-channel amp will get you all the way there.

    Also what jbooker said.

    well, i dont have room to do a 7.1 setup just thought i can use the extra ch to bi-amp and improve performance. So i've decided on a Yamaha V667 which have 7.2 preouts. But for the outboard amp i'm totally clueless, since im only setting up 5.1 should i just get a 5.1 amp? Also i'm considering CSI A4 for center and FXI A4 for surround with Bic F12 as my sub. ty for the replies.

    Pairing a Yamaha AVR with RTi A7's is not the best idea, IMO. As mentioned, it would make the speakers brighter than they already are even using an external amp because you're still running the Yamaha pre/pro section.

    Bi-amping with an AVR is rather pointless because it's not really bi-amping at all. You're better off replacing the stock speaker jumpers with high quality speaker wire.
