Audience Conductor "E" or "SE" speaker cable?

To Zd542, Thank you for the explanation, and comments. I appreciate your time and audio expertise.

Under $500 for an a 8ft pair?? You might want to check the Audio Art SC-5.speaker cable I noted above However, they may be equal to, or not much better than Signal Cable "Ultra"

I home auditioned Clear Day's single silver ( not double silver)and found them better sounding than Audio Art SC-5. However, I wanted more out than what they had to offer, but did not want to pay over $600 for the double silver version.

You might want to talk with Audio Art's Bob Fritz. The SC-5E is above the standard SC-5 and is supposed to be much better than entry level series. AA is a very detailed and revealing cable and you might find that its slight lean to the bright side could provide a welcomed degree of liveliness to the Harbeth's you have.

Finding the right cable to meet your sonic needs is a real pain in the ass, and has made me want to give up this audio hobby obsession forever.!!!

TO ZD542: That is good to know about the Audioquest CV6 and CV-8 which I have several ads on AG over the last several months. I never took their speaker cables seriously, only because I owned some of their basic interconnects which were terrible and looked cheap

However what is the FUNCTION OF THE DEVICE they attach to the end of the cable, usually by identified by a number like DBS v72?? It also has a small push button and green LED
