How to get the most out of my equipment?

[NvidiaDan]

Hey all,

I got a Asus Xonar DS card for christmas, but i'm a total noob when it comes to sound.

At the moment i'm using a 3.5mm jack to RCA cable to connect it to this Aiwa Hi-Fi.

And using 2 old Acoustic Solutions monitors.

I know this is extremely old and budget stuff so im not expecting great quality but is there anything i can do to improve the sound? Would and optical cable be worth it? Or should i look at new equipment?.

Thanks.
