Cables, Cables


I am sure this was asked many times before, but anyway here I go…
I've been using Home Depot 12 AWG copper wire, bi-wired. It sounded very good to my ear. After reading up some, I've decided to buy some really nice pre-made wire; after all I am always looking for some improvements. So, I bought Audioquest CV-4 not bi-wired. Brought it home, connected and the sound became flat and dull. Am I misunderstanding something here?

Moganes, did you connect the speaker cables to the top terminals? Or whatever the mid-high terminals are on your speakers, that's where the speaker cables should be connected to. In case you hooked up the speaker cables to a woofer terminal, your lifeless sound may be a product of the jumpers providing signal to mid-highs and not the speaker cable. Take a look.
Do try Audphile1's suggestion and also be sure the jumper is decent -- not the stuff that typically comes with the speaker. A short length of the Home Depot wire should do the trick since you had good experience with it.

If it still sounds worse, even after some burn-in, enjoy the Home Depot wire, sell the Audioquest and think of all the money you're saving!
Ozfly, good point. Something I forgot to mention is the jumpers quality.

Another thing Moganes, let the cables play for a while before you make up your mind. You may get used to this sound and not be able to go back to the HD wire.

Also, when you get better, more revealing cables, the flaws of your components show much easier.

P.S.
AQ cables in general have a bit of a dark character to their sound.
A few years back I was using black 18 gauge zip cord for my tweeters. It was quite good and bettered LAT, Kimber, and JPS mid-line cables.
Any difference is likely to be inaudible or just barely audible - the huge difference you describe sounds like a problem somewhere (crossed wire giving incorrect phase maybe?).
