bi-amp an Onkyo 603?

[bms]

Does anyone know if you can use the rear surround speaker outs on an Onkyo 603 to bi-amp fronts, in my case, rti8's? I have never bi-amped before, so would I see an improvement in sound?

bms - if it's possible to bi-amp with the 603, the manual will say so, AND give instructions.
Before I bought an amp, I'd bi-amped my RTi10's to an Onk 705. There was substantial improvement.
Others have reported little to no gain....YMMV. But to me, it's a quick cheap thing to try.

Thanks - I'll check the manual again.

It was possible with my old 605.

I emailed Onkyo and they said this:

"Unfortunately the unit was not designed for the Bi Amp feature, We have newer receivers that has the Bi Amp feature. The model that would replace the current one that you have is TXSR 606 which does have the option of Bi Amp for the speakers.
Thank you,

Oh well. Now I'm thinking about a Denon. I like the avr 988, 2808, or should I go for for the 2809, which is $400.00 more, but a just-released model?

Any opinions?
