    I have four identical 2 channel poweramps in a 7 channel system (one amp is biamping the centre) It shouldn't be too expensive, as I'll only need a any decent two channel poweramp for rears - move the amp from the rears to the mains, buy another length of speaker cable and bananas.

    The 2 channel amps are 2 x 100W into 8 Ohm. Processor is set to small 80hz.

    Do you think it's worth it?

    Thanks

    Yep Ben- will be using two identical 2 channel poweramps, with the non-matching/lesser quality on the rears.

    Yes, It is the best money I ever spent. If you already have matching amps hook it up and give it a try.

    Depends on how 'lesser' a quality the amp for the rear channels is going to be. If you pull your Audiolab off the rears to power the fronts there will be a slight improvement in performance but you have to weigh this small gain in comparison to the loss at the rear. Are you still running a separate music and AV system?

    Right something to think about:

    Bi-amping can lower IM distortion in the critical mid range frequencies and to which the ear is most sensitive. You also get about 4dB more headroom, which can subjectively increase the perceived dynamic range.

    Doubling the power from a new higher power amp will give an additional 3dB of headroom

    So why do people recommend lager power amps over bi amping? You would need to more than double the output to get a similar effect?

    Yup Gary, two seperate audio systems.

    Since rear channel is less important IMO, I'll get something like a Arcam Alpha 8P/9P. I'm pretty sure I don't need a 100W poweramp for rears.
