How to choose the kind of cables for your system?

FWIW cables do make a differfence but how much depends on a lot of things but especially your expectations and your listening skills balanced with your check book balance.

What I would do is to buy some inexpensive cables which are a high value, sonically and financially, and use them as a bench mark to compare with other cables as they come and go to finally settle on what you like best and are willing to pay to get.

I'd start with some Canare 4S11 cable. Pretty good stuff I think and about $1+ a ft bulk.

What are some good power cables for the amp?
Interconnect for amps, preamps cd transport - looking at balanced/ XLR...
ZAes/ebu digital cables
Speaker Cables..
My system is about $36000

Actually I don't mind spending more than 10% for cable ... Just want to get the system to sound right and good...

Check with the cable company http://thecableco.com/ tell them what equipment you have and see what they suggest. You can try before you buy. Also contact the Mfgr of your equipment and see what they suggest. Let them know your musical likes and dislikes. Good Luck to you!
