I have my computer hooked up to my home audio system which is a Deenon 3808 and a pair of Axiom M3's.

I have a HT OMEGA Striker sound card in the computer. I'm using the SPDIF output from the sound card to the Denon. The sound card SNR is only 100db. Would my sound be better with a sound card that has a SNR of 124db?
