++++1 for AntiCables. The 2.1 speaker cables are great entry level cables, but for mid fi and up, I'd start with the 3.1 cables......at $250 per 6 foot pair with Z bananas, they are an absolute steal. I have not tried them, but the 4.2 Flex cables at $470 for 6 foot pair look really interesting. Please do remember that AntiCables do take longer than your average cables to break in, mine started to settle in at about 150 hours....but damn they will reward you.
I also recently ordered a pair of Morrow Audio SP6 speaker cables, as I had an older pair of Morrow interconnects that I used to get the 65% off in trade in. They are being burned in at Morrow right now for 20 days, and should receive them in about a week.
Additionaly I have a pair of Zavfino Nova OCC speaker cables, DHLabs Q-10 speaker cables, and a pair of Micca Chinese made speaker cables that Steve Huff tried and liked. I'm currently working on a "from scratch" listening room that should be finished by the end of the year, where I'll have 2 amplifiers and 3 sets of speakers: Buchardt Audio S400 MkII, 1980s Infinity RS Kappa 7s (GR Research upgraded crossover, upgraded internal wiring, new gold over copper Viborg B603G binding posts), and "yet to be purchased" higher end speakers (Joseph Audio?, Fyne Audio?, Tannoy?, etc) At that point I'll start a major speaker cable shoot out for fun.
