Jumper Cables - use the stock or should they be upgraded ?

68Pete if you are happy, and big improvement shows up, cool, enjoy it, czarivey it's only stupid when I buy things I can't afford, it's a matter of choice, I respect every choices you will have..,

If your cables are set-up for bi-wiring, it is usually best to do so.  That being said, DH Labs/Silver-Sonic offers seriously high-quality custom jumper sets for under $50.00.  I use them, and they made a very noticeable difference.
