Obviously there are a million and two ways to achieve a setup like this. How about this for a scenario: Connect your Oppo and your HD cable box to your 1070 (assuming you
still have your 1070 ) using digital audio cables along with any video switching you may be using (or take the video straight to the display). Then connect stereo analog cables from the Oppo and the digital cable box to a secondary receiver (like
this from Audiogon , perhaps, or even that AVR587 you mentioned for $250) which would then drive the bedroom and bathroom speakers. I suspect that you could find a used stereo receiver for this purpose at a pawn shop or online auction site for around $100 or less, assuming you didn't already have one lying around that you could use for free. Your RF remote could control input selection and volume from the bedroom. If the receiver you used for the bedroom included digital inputs and your HD cable box has more than one digital output (mine has both optical and coaxial), you could even connect both sources to both receivers with digital audio cables. This is essentially identical to what the 990's second zone and a two-channel amp (or two spare channels on a seven-channel amp) would accomplish. Certainly a separate amp like the 7075 or 7125 would handle the 4 ohm load produced by both sets of speakers better than a receiver would, such that you could hook both speakers in parallel and forget about it (might need to be a little more careful about that with the 587 or a used receiver). The only reason that I suggest a scheme like this is a concern about allowing one feature that is used peripherally drive component selection in a direction that may yield less performance for the core purpose (and feedback from 1070 owners makes me suspect that the 1070 will sound better than a 3806).
