I'm having a tough time getting a noise-free signal from my XM radio into the Empeg aux input. I've tried additional grounding, ground loop isolator, power line filter, better cables, pre-amp, etc. I don't think it's XM... if I unplug XM and ground the signal lines at the plug, I still get unacceptable noise. If I mute the empeg - absolute silence. Also MP3's sound great, so I don't think it's the empeg->amp path.

This is frustrating because I'm trying to get music from one digital device to another. What I really need is a digital toslink->toslink connection. Toslink is available on the XM side, but not on the empeg.

There were a few discussions a while back, and it seems the hardware is possible, but would require software hacking. I'm a hardware guy myself (chip designer), but I have done some software work in the past and would be willing to help out in any way possible.

Is anyone currently working on this?
