Sitting in my study this morning, listening to some Chemical Brothers, it occurred to me that I could use a bass bin for my PC.

So: I'm wondering whether there exists an amp that takes SPDIF and will output 2.1 audio (stereo + sub), that also has a (switched) socket for some decent headphones. I'd prefer SPDIF to eliminate analogue noise from the PC. I don't need input switching -- there's only one PC. I definitely want the ability to leave the headphones plugged in and switch outputs.

Of course, I could just use my spare empeg, but I like the media buttons on my keyboard...
