Need help with monitors setup

Hello,

I am new here and yes, this is another boring topic asking the same questions again and again, but i am desperate to get your help, and i will appreciate it.

As many others i have moved from pc speakers to monitors too, I've chosen KRK RP5 + RP10 and i will use them mainly to listen music and will not do any recording, I will have them connected on pc. However I would like to use balanced cables because from what I've read, rca cables can pick up surround noise or when scrolling and such things. I really want to get the best out of these monitors(for a low budget) but im prepared to spend some extra money on it.

From what I understand, if I want to use balanced cables i need to buy some extra equipment, and i need you to help me choose it. I will probably buy some passive volume controller too because its practical.

I will be ordering everything online and im not sure if i understand properly how everything is connected and exactly what cabels i need. 

I hope i'm not asking for too much, thanks in advance :)

a little bump but nvm the above post.  For now i will just get UCA202 and connect everything with rca cables, i guess there are some "better" shielded that transmit less noise. What cables would u recommend me? And im not sure what would fit here either, i know they're rca but i will order them online so it would be good to know what to look at, thanks.

I think you missed my last post, but anyway can someone please tell me what cables do i need to connect all this? Please be specific so i wont be asking you the same again :)
