I used to not worry about cables and speaker wires using Sound King 12ga. fine strand for years. But, as my main rig moved up the food chain and I bought gear with greater resolution, I realized I was shortchanging myself. I experimented with many types of cable and plugs as I went down the DIY road finding that indeed different types of wires have a different sound to them. Specs or not, it is my ears that determine whether they are used in my rigs or not. (70% of my cables are DIY) I subscribe to Stereophile and read the articles I find interesting, same with the Absolute Sound. To not keep up on whats new and trending would have cost me a lot of music, and a few pieces of fantastic gear as well. Everyone can enjoy this hobby as they find fit with no fault called by me.
Enjoy your rigs my friends, but don't stifle those who are willing to explore. Closed minds lead to missed oppurtunities in life as well as our hobby. IMHO
Enjoy,
Jim
