[QUOTE="BugsBunny, post: 67937, member: 19983"] A soundcard can make a big difference and SPDIF out does not necessarily signify that you get a 1:1 signal from an audio CD! Most onboard sound and consumer cards (soundblaster audigy...) resample the audiosignal internally and put out a signal with a sampling rate of 48kHz. Most audio files have a sample rate of 44,1kHz. I've an external AD DA converter that indicates the sample rate and I already conected different SPDIF devices (onboard sound, soundblaster ...) so I know what I'm speaking of. The internal resampling often is crap so you get a worse sound compared to the original CD. Someone here even complaned about that once. He conected the HTPC via SPDIF out but it sounded different compared to conecting his CD Player to DA converter. But all that is relative for sure. If you have a rather high end HIFI equipment and are an "audiophile" listener with some external DA converter, better get a soundcard that does not resample the signal internally. If your HIFI equipment is not worth much, most probably you will not hear a (big) difference and you can stick with the onboard sound. [/QUOTE]
