Hi all - I use an HTPC with an SB Audigy - feeding my Dennon3802 via the digital coaxial out. A couple of questions. 1. Will buying a better sound card give better sound - bearing in mind, as far as I undersand, the SB is merely "passing on" the digital stream from the DVDs to the amp. 2. I use a very shoddy, long, home made phono lead to get the signal to the amp. It's digital, so the quality of the cable should make no difference.? Thanks!
