You don't need to use an op-amp, you can just use resistors.

I'm intrigued now, even if it is impossible!

This thing gets ridiculously hot though, might have to get longer bolts and add an old PSU heatsink to the case.

On the rane why-not-wye page, which seems pretty helpful for this http://www.rane.com/note109.html

What sort of resistors would I be looking at using?

Can't work it out cause I'd be going from stereo headphone level to two mono at headphone/aux or whatever the ideal for this amp is.

Still gonna use the RCA's for output, once I've properly isolated and wired them that is!

You can probably tell I'm quite new to the DIY aspect of this. XD
