Update Merlin TSM-Speaker Cables please

Bobby,
Which Signal cable? 13 AWG, 10 AWG, single run, double run single or internal bi-wire?

Nickway,
I read the posts and review. Hard to argue with this - cost a fraction of the competition - cant really lose much except a few bucks. After all that, I need to hear them, if not on Merlins, then on my other speakers. Thanks for the suggestion; always willing to try something that wont break the bank and teach me something new............maybe even put Stealth Indras and PAD Dominus in a new perspective.
