Interconnect advice needed

The SKW cable look big on the photo but actually it's not, and very flexible as well.

i'm trying to go OCC copper cable as possible, some of my ICs cable even OCC silver  

This is an incredible, fantastic value cable. Just terminate it with your choice of RCA plugs, using one silver wire for +, one silver wire for -, cutting the drain wire flush at both sides, and connecting the shield only at source end. 

It's the best cable I've heard and just unbeatable at the price IMHO.

Please look into Townshend F-1 Fractal interconnects. I have them and their Fractal speaker cables and they are fantastic.

Unfortunately twice my budget.

Look like you will be having fun this week-end with your cable shoot out. I think you need to audition mogami too, you will be pleasantly surprised, have fun.
