First off, I may be getting in over my head here, so please forgive the likely basic nature of my question.
I had a hard drive on a 2 drive system die, and so I took it as an opportunity to build a whole new computer. After I had my new system, I got the other one up and running again, and now it's sitting in a corner. My plan was to sort of make it a poor man's media server and connect it to my home theater system. I figured I could run itunes through it and watch movies via the netflix watch now deal, etc.
The problem: the sound quality of my songs on itunes is horrible when played this way. When played through my PC and my $29 cheapo brand speakers, while hardly audiophile quality, it sounds MUCH better than giong through my reciever and out of my paradigm mains.
The setup, in case it's relevant: soundblaster sound card connected to a normal input on my receiver via a 1/8" to RCA plug.
What is the cause, or is it just that decent speakers really illuminate the poor quality of my itunes files? Again, I am perfectly happy with the quality of the sound when played over my normal cheap pc speakers.
