    Using an A 85 with a Meridian 506.24 and Kef Reference 2 speakers. Is the addition of a P85 worthwhile i.e.will I notice a big difference in the sound?

    Simply put. Yes.

    You'll gain clarity and control to the sound, it will basically sound much better.:smashin:

    Question: I use my A85 in my AV setup, is powers the fronts. If I get a P85, could I use it to drive my surrounds as well as bi-amp the fronts? I would then connect the fronts to the A terminals, and the surround to the B terminals.

    In surround both terminals would be switched on, in stereo the B terminals would be switched off. Or would this present to high a load in surround?

    It'd be too complex to try I think, not worth the effort.

    Stick to just fronts.

    Well, not worth the effort...

    Bi-amping the fronts would be worth the effort.
    Driving my surrounds with a P85 instead of a Marantz SR4200 would be worth the effort.

    If I could do both, that would DEFINITELY be worth the effort ;)

    Having thought about it I don't think it will work.

    If you are bi-amping your fornts then you will need the P85 on the fronts for AV usage as well or you'll be missing part of the front channels. Either the treble or bass.

    A and B outputs run only of pone pair of amplifier channels not 2.

    You couldn't use the P85 to bi-amp the fronts some of the time and at other times act as amp for the centre and 2 rears, but I don't think thats what you're asking (sorry but you didn't ask the question very clearly). I think you want to bi amp your front left/right with your A85 and the 3 channel P85, then use the 3rd channel to power your centre.

    Having said that, I may be way off the point here as I've never seen the P85 3ch amp ... but doesn't a it just have 3 line level inputs. Connect 2 to the pre-outs of the A85 (which in turn is connected to left and right pre-outs of the SR4200) and connect the 3rd P85 input to the centre pre-out of the SR4200.

    Then connect treble left and right to the A85, bass left and right to the P85 and full range cable for the centre to the P85. The rear channels would be connected directly to your SR4200.

    Doesn't sound difficult / complicated to me - though I've not seen the connections on a P85 3ch power amp so I may be wrong on if this would work.
