Bi-amping for HT

I have an older Audio Research D-90 amp and SP-12 pre amp that I absolutely love for music. I also have a HT system that's mid-fi with a Pioneer A/V reciever that I would like to upgrade.

My question: is it possible to use the ARC D-90 for the HT front speakers by using a Pre-out from a newer receiver?
I mainly listen to FLAC/WMV files off my PC hard drive through a Music Streamer which works and sounds very nice.
Any recommendations on receivers with Pre's that could do this?

If I get a new Pre w/remote that still won't allow for 4 channels, correct?
Wrong - you need to focus on what's going on in the scheme I described. for music - it's 2 channel, for HT it's 5.1, or 7.1, or whatever you configure. Furthermore, in HT Mode - all channels are controlled by the Receiver remote. It's only in 2 channel music mode that you don't have remote control. You can remedy this by getting a new preamp that has remote.

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?

that's right. Think of the preamp as simply being a passive connector between your HT receiver and your power amp when you're using it for HT. This way the volume control is fixed on the SP12, and the volume for all HT channels are controlled by the remote for the receiver.

If you do decide to buy a new 2 channel preamp - you may want to consider getting one that has HT bypass built in. It's better and more convenient, but not essential.

A Manley Skip Jack will allow you to use both your SP12 and your Pioneer receiver. You'd run your front left and right speaker line outs from both into the Skip Jack and out to your ARC D-90.

let me get this straight Byfo . . . you want him to buy a $900 switch so he can connect his $300 receiver and his $470 preamp to one amp, when both of them already have the capability to do this without an external switch?
