    Has anybody ever tried a 6.1 setup with Class A Amplification on all the speakers (except for the subwoofer)???

    I'd imagine you'd use a fairly descent pre-amp connected to three stereo Class A amps, anybody got clues as to how it would sound???

    I have a highly class A biased AB amp (up to 25watt pure A). I love the sound of my stereo treo, even on the end of the yamaha i have been using as an interim solution! But i dont think thats necessarily because they are class A (ish) rather just because they are good amps.

    A warning..... dont forget heat, even with my amps the room will raise in temperature by a few degrees through a film..... bettwe than most heaters!

    Well what daft idea's been running through my head is...

    Using an A/V receiver as a pre-amp and using three PM7200 amps for the power-amps...

    If people convince me it'll sound notably better than a sub-£1200 A/V receiver I may just experiment with this idea!

    PM7200? by whom? If they are any good, it is likely the performance should be superior.

    Marantz - did you not read the What's Hi-Fi review? (They adored it).

    Yeah the PM7200 is a class A amp which I've found for £230.

    Does the PM7200 have a fixed gain in that bypasses the volume? There is a processor IN/OUT at the back but not sure what it does, this would negate the volume setting nightmare of 3 amps. It should sound fantastic if the reviews are anything to go by but would be very tall, I had thought of adding one to my amp for stereo but have not had the mono-blocks long and really need to get a decent source first. Am very interested in the fixed gain do you know off hand, What receiver were you thinking of running them with.

    The amp does have one set of 'Processor In/Outs' according to the Marantz website...

    I've emailed marantz asking them what they think of the idea and whether it'd work...

    We'll soon see!

    Oh and, I'm not sure what to use as a pre-amp yet. First thoughts are with AVR2803, but that might defeat the purpose of trying to attain this quality of sound...

    Suggestions welcome..

    (Oh and I have the space so don't care how much all these amps take up in the room - and I like the heat!)

    I assume you can get them at a good price, the 7200's that is.

    Gutted I read a review on these the week after my 6100's arrived and at the same time as a pair of MA24's showed up on e-bay, which are an alternative if you can find any they are 25W Class A mono-blocks which the guy at Marantz told me used to retail at £2500 a pair, they went for not much more than my 6100's, all I need now to finish me off is for you to tell me that the 72 has AV bypass.

    Well Marant'z email address doesn't actually work, so I'm going to have to Phone them tomorrow to find out if it does - I'll keep you posted...

    If anybody else on the forums knows feel free to contribute.
