Howdy AR.comians,

I am possibly looking to buy different "flavors" of Op-amps for the Asus STX sound card. Here
http://usa.asus.com/product.aspx?P_I...K2f&templete=2
is the link to the product's specs.

What do op-amps do and how can they/do they effect the sound. Also, where can I shop for op-amps and what would you recommend trying if I had to buy up to five?

Thanks for your time.

Jason
