should take in TOSLINK or S/PDIF (eg. from the xbox) (and maybe would be nice to have several possible inputs)
should output in a stereo format for headphones

Things to generally look for:

amps/receivers
- most Harmon Kardons, including the AVR140, AVR240, AVR340
- Kenwood VR-9070
- Kenwood VRS-N8100
amps/receivers that have only a 2-channel amp
- Kenwood VRS-7100 (back) (manual)
- Yamaha HTR-5840
