Bi-amping for HT

Thanks for the responses and yes I realize this is not bi-amping, my mistake. I'm just trying to incorporate the ARC 2 channel gear into a HT set-up.

I understand Bdgregory's set-up recommendation but not sure that's a reasonable method given the manuel nature of the SP12, warm-up time, etc. Was really trying to get everything to work off remotes and eliminate the SP12 Pre but it appears that the sound quality will not be so great if the SP12 is replaced by a 'standard' HT receiver Pre.

Yes, I have considered that but would still like to have the rear speakers for movies and sports. They do fill in nicely but just can't figure out how to keep the rears with the ARC 2 channel gear.

I could go with a nice Marantz or other HT receiver but pretty sure I still won't get that ARC tube sound. If I get a new Pre w/remote that still won't allow for 4 channels, correct?

OK, so I would need a new pre w/remote AND a new HT receiver w/pre-outs (my current Pioneer does not have speaker pre-outs). Hook-up the front speaker pre-outs from the new HT to the new pre-amp In's? That would give me complete remote for TV and music.

Or, just get a new HT receiver, keep the SP12, hook it up similar, and use the preamp manually for music but it will work remotely under the HT receiver if I keep the volume set at a predetermined level?

If my current Pioneer had pre-outs for the speakers then I'd be set but it only has the pre for Subwoofer.

So just to clarify, I need a new HT receiver that has pre-outs for the front speakers(most current ones have pre-outs for all speakers). Connect the Pre-out L&R fronts from the HT to an Aux input on the SP12. Run my normal connection from the SP12 to the D90 amp. I don't believe it has a bypass mode.

I would have to manually turn on the SP12 because of no remote, with it set to the Aux input. Set volume to a predetermined level and from then on I can run the volume for all HT speakers from the new HT receiver remote.

Listening to music only with just the fronts and SW would be done as normal using only the SP12 and D90. I could listen to music in 4.1 if I connect my source to the HT so the fronts would go through the SP12 but the rears would be handled completely through the HT receiver. I could hook a different source into the SP12 and use just 2.1.

And if I get tired of the manual switching I can upgrade the preamp to one with a remote function and possibly a bypass function.

Cool!
Thanks a ton.
