I'm looking for a good quality switch to change the optical S/PDIF source between my Xbox and PC on my headphone transmitter. Does anyone have one or know of one which they can recommend? I've seen some at £50 and some at £300. I don't need many features, but remote control would be nice. I don't think there's any point in having one with more than 2 ports because this is for my gaming setup and I can't see me having any more than two devices here in the future, unless a 4 port one offers better quality than a 2 port one.
