My take on speaker cables based on my experienced alone.
I've been to the Acoustic Zen route (Satori first then Hologram MKII's for several months) as well as Analysis Plus (Oval 9 double run), Purist Audio Design (Museaus, and Colossus for a brief moment), Synergistic Research (Designer series), Nordost (Blue Heaven Rev. 2 bi-wire), MIT (330 and 750 if I remember correctly). The longest time that stayed on my system (2-ch) is the Hologram MKII. I still have the Satori though for HT.
From extensive reading, I was very intrigued of what I've found. Most of the highly respected DIY'ers (Chris Brady of the Teres Audio fame for example) does not use any of the cables that I mentioned above. In fact, a great majority of them uses the ff:
Teflon encapsulated, evenly spaced, pure Silver Wire (at least 99.99%), bare wire termination. For bi-wire requirements, 16 ga. for the woofers and 18 ga. for the top (this ratio is very important).
Tried it and the result for me supports my accumulated experienced in selling the majority of speaker cables that I tried above. Best of all, bi-wire config for 6-8 feet pair only cost approx. $6.95 per foot.
Maybe you will be interested to try it. Again, it works for me but cannot confirm that it will work for you.
Just another option you might find interesting....
