well i plug a audio cable from pc to amp not sure if its RCA
Do the connectors look like this?
yes 2 connect to the amp and one wire connects to the pc.
Yeah, in that case I'd suggest the 2496, although you'll need a plain RCA to RCA cable, rather than the one you have at the moment.
Thanks for all your help before i decide to buy a new comp i will give you a full list of components . Thank you once again
