I've got about 50gigs worth of 192kbs mp3's on my pc and want to know how to squeeze the best out of them. My current set up is as follows:

Amp: Rotel RA-971 MkII Details
Speakers: Kef Q55's
Sub: Eltax atomic 10.
Soundcard: onboard realtec 5.1.
Speaker cables: Cant remember the exact brand but picked them up on recommendation from audio ex******

Any ideas?

Thanks guys...

You really think i should ditch the sub (it's great for movies n 24)? I was thinking of getting a sound card with a sub out so it's not parasitic on the hf line.

Anyways back on topic...i've got a budget of about £50 dont mind going 2nd hand...wut u recommend?
