Can anyone recommend a good quality sound card with digital coax out? I'm using an Abit AN7 which has Optical S/PDIF out to my amp, but I've been told that Coax is better. Unfortunately, the mobo's audio header only has 2 S/PDIF pins on it, one for out and one for in, so I'm not sure if I can use these with a coax header bracket. The amp can do all the digital processing i.e. Dolby Digital, DTS etc. so all I need is digital pass-through. Thanks, David.
