@ Eliizebeth,, Hi, I have seen you around on audiogon alot, I like you!, To me, you are the queen of audiogon!, Its likly I say this is because there is no females on these threads!, I was fortunate that I was able to get my omega gold speaker cables 6ft new for 12,500.00! A savings!, equipment wise, I have a Krell 700cx amp, Ayon 2s cd-player running direct untill I get a Ayon 5s or a pre-amp, The 2s sounds good!, I have been building this main system for 13 months and have a long ways to go, I have seen your equipment you use in your threads, kudos! great equipment you use Elizabeth!I would enjoy talking to you more!, your likes and dislikes of audio, that would be nice!, you do have my respect!, cheers!

Using a 20 meter length of speaker cable, especially in conjunction with a speaker whose impedance reaches low values at some frequencies (3.1 ohms in this case, as indicated under the specifications link here, requires that basic electrical parameters (resistance, inductance, capacitance) be carefully considered. All of those parameters are directly proportional to length. I second Elizabeth's recommendation to avoid the 8TC. For a 20 meter length, its resistance is marginal at best, and would exceed B&W's 0.1 ohm recommendation for maximum cable impedance by nearly 50%. On the other hand the 12TC may not be suitable either, depending on the characteristics of the amplifier you are using. It's capacitance per unit length is on the high side, being specified as 1400 pf per 2.5 meters. That would amount to 11,200 pf for 20 meters. That is high enough to potentially affect the sonic performance of the amplifier, and is in an area that has even been known to cause some amplifiers to oscillate and self-destruct. Obviously, at that length cost and budget are major factors as well. I have no specific suggestions to offer, but I would avoid cables for which specifications of resistance, capacitance, and inductance are not indicated by the manufacturer, and cannot be obtained from them via an inquiry. When you arrive at a preliminary selection, you may want to post back in this thread with an indication of its electrical parameters, so that we can comment on them specifically. Regards, -- Al |
Interesting argument about getting as much tire on the road, as it were, with multiple lengths of mediocre 12 ga cable. The problem with the idea is that one of the most revealing and musical cables is the Omega Mikros from Mapleshade, the center conductors of which are 54 ga. In case you're wondering, 54 ga is about the diameter of a human hair. So much for the more the merrier theory. |
