Hey there, just looking for some advice, I am stepping up from a Integra dtr 5.3 @ 80 wts per ch to an onkyo tx-nr5007 @ 145 per ch This receiver allows me to bridge or bi-amp my two mains instead of surround rears, which I do not curently use anyway. Should I BI-amp the speakers or bridge the channel for double power? The main reason for the upgrade I really wanted more power for 2 channel stereo music as well as hdmi switching. O and BTW..I am using 2x m60v2 1x vp150 2x qs8 1x ep350 and plan to add a second ep350 very soon.. any help or advice would be great

You will not hear any audible difference in doing the passive bi-amping.

Thanks Rick ..So I take it I'll bridge 2 channels for for what I want, and if so, will the fronts be way too loud when I switch to 5.2 surround for movies. Or do you know if the auto surround setup will adjust for that? I'll be setting this up tomorrow and would like to have a game plan so I only have to do this behind the rack wiring this 50 pound thing once..lol Thanks again!

If I were you I would stick with standard wiring. Even if you do the bi-amping, it wouldn't be bridging, you will be fine once the unit is calibrated.

ok...I'll try it like that ..but do you think that 145 per ch will be lots for "really wicked" 2 channel stereo as appossed to the 290 I counld get by bridgeing the 2 back channels..thanks again I apreciate your imput..Paul

OK, ya see, even if you did do the bi-ampimg you would still only be getting 145 watts (max) per channel. Removing the straps from the rear of the speaker only changes the route in which the power is received from amps. The top would get 145 and the bottom would get 145. With the straps in place and running one speaker wire the top and bottom still get 145. It does not change the total watts received.

Ok but Im actually talking about bridging feature of the reciever, according to the manual it will actually push double the wattage to the front main speakers by bridgeing the front right and rear right channel and same to the left channel and leave the straps on the speakers. Thanks again!

Even though that is what the receiver manual says, it is misleading. Your not getting double the power.

Reading through the manual it does indicate bridging will almost double the power. I haven't seen the impedance chart on the M60s and if they dip low enough it could present problems in BTL mode.
I sure enough know one thing, my Onkyo runs pretty hot even running 8 ohm speakers. Running in BTL mode is going generate a lot of heat in the amp if it truly does real bridging..

I bridge my 2 side M80's with my Denon amp with no heat issues. My 2 front M*'s are run along with my VP150 with the A1400-8. When running Audyssey the speakers are calibrated very close in their adjustments. Take that info however you like ![wink ;\)](/boards/images/graemlins/default/wink.gif)
