Best low cost speaker cables for my system?

Thanks for the ideas!

Sean,
Your remarks are way over my head, unfortunately. The DH Labs Q10 uses a pair of 12 guage wire and a pair of 14 guage wire within one jacket. I don't know how this compares with your suggestion of 4X14 guage "spiral wrapped star quad design".
Tvad: thanks for once again offering suggestions for my system. I will look into the Canare cabling you suggest.

Tvad: Jeff At Value Audio states that the combined guage of the DH Q10 is 10, hence the designation, Q10. As I'm not a do-it-yourself-er, my tendency is to go with the Q10 rather than buying bulk cable and terminating it myself. The Q10 seems to address the concerns Sean brought up about long cable lengths, plus it's well reviewed and within my budget, and I trust Jeff. The salesman at AudioFX in Sacramento, where I bought my system, did not believe the lengths of speaker cable required by my room were inherently problematic, by the way. Many thanks to all for your suggestions-- Audiogon rules!

Nice to hear some votes of confidence for the DH, but Tvad, I will look into the Ramelectronics stuff as well.

Tvad:Yeah, I guess I figured that as the Q10 uses both copper and silver it would likely not push the sound of the system too far in either a dark or bright direction, but this is just a guess on my part. The reviews I've read of the Q10 state that it's pretty neutral (admittedly a relative term). Value Audio will lend me a 10" demo pair to try out. If I had more cash I would likely just upgrade my current Transparent "The Wall" speaker cable to Transparent Music Wave Plus because the current tonal balance is very good, but I don't have $ 1500 to spend on speaker wire!
