Bi-Amping, best way??


I'm gonna have a play at biamping, since i have two Marantz PM6010OSE's, and wanted to know what people thought the best way of doing it was.... i'm think that i have CD into amp 1, then take tape-out from amp 1 into Aux in of Amp 2, and then have Amp 1 drive the Hi of Speaker 1 & 2, while Amp 2 drives the Lo of Speakers 1 & 2.

anyone have any thoughts in this setup, or can suggest an alternative/better.

btw the Pm6010's don't have any sort of pre-in/out.

cheers

Sure, Oz. Purist Audio, Nordost, etc., all make y-adapters. I used a pair from Cobalt Cables, perhaps not the best but they did work.
thought i'd let u all know how the biamping went, all my cables and things have come, also the 2nd identical amp (Marantz PM6010OSE)....

well i setup the system in vertical mode, with one amp for left speaker driving both hi/lo and other amp for right speaker ditto, and i just split the source to both amps, with left split into l/r on amp1 and right split into l/r on amp2.... so the results.... Brilliant!!!, the musical depth is much improved, the defenition in each speaker is a big step-up, the sound-stage is much the same, there is a good deal more bass, all in all the music is a lot more alive than before. I'm lacking real detail but thats more down to my very old CD source (Marantz CD54), i've got a Sony SCD-BX940 coming soon to have a play with, so will drop in the odd SACD to see how it sounds, but at the mo. all in all very happy, i'll have a play at changing to horizontal bi-amping with one amp for Hi's and one for Lo's just to see the difference, just more of a faff getting the balance right on the two amp volume control.

anyway, off to pour a beer and have a listen....
Ok, i've tried Vertical bi-amping with 1 amp for each speaker, and the sound was much fuller, and the mid-range was a lot stronger, i think my wife described it as been more 'in your face' (she's a violinist), so though i'd swap things around to horizontal bi-amping with one amp for hi's and the other for lo's, and with her fine-tuned ear she was saying that there's less mid-range but you can make out all the instruments and a lot more detail and colour (not coloured, as in valve amp, but sparkle and life), but not as much force.....

so looks like for my setup then Horizontal bi-amping works best.... was it worth the extra bit of cable here and there, and also a 2nd hand identical amp.... Yep!

Has anyone tried bi-amping using different amps ie. one ss amp that has great bass and one ss amp that has great highs and mids? Are there any issues running different amps that have different power output 600 watt amp for the bass and 200 watt amp for the mids/highs
