Reply to Choosing the right cables for your sound output for the S2?

Sorry if this has been posted,

I noticed in Ean's vid he uses 1/4" inch cables for his main outs, just wonder if they are custom made and I also noticed they both were different.
What i'd like to know is what is the difference between using the standard RCA on the outputs instead of using the balanced TRS outs?.

Secondly what TRS cables work best with the S2.

Thanks in advance,
V.
