Another option is to switch to an preamp that has dual main outs. I did this recently in an attempt to run two pair of speakers as a "super-speaker" (for lack of better term). If you check my threads, I asked which preamps have dual main outs.
Interestingly, I ended up going with none of the great suggestions given me. I saw a Rogue Magnum 66 for sale; the owner told me that the tape out is internally switchable to a second line level out! It was, and I'm using it as such.
Another possibility (you may want to discuss with someone who knows more of the technical aspects) is to split the signal using an Audioquest RCA "y" adapter. They're only $25 per pair, and might do the trick. Lot's cheaper than second preamp!
