Thiel Owners

The Goertz design is high-capacitance, which may cause some amplifiers distress in the trans-audio high frequencies, which produces down-reflected audible consequences. Correcting that capacitive load makes the amp run truer to form.

thanks Tom.   is that true for shorter lengths such as 8' as he is running 13'

Ron, shorter cables are always better than long. But parallel (not twisted) conductors like Goertz are inherently capacitive. If there is a problem depends on the amp. But Thiel's low-impedance results in more current being drawn through the cable, so any capacitance problem is likely to be exacerbated. I suggest using the Zobel filter.

thank you so much

FWIW:

I had a very long run for my speaker cables (my source equipment is in a different room) so I went with Belden 5T00UP 10 awg cable (bought from Blue Jeans cable).   The specs were excellent and just what I needed for long speaker cables without loss of sound quality (see review with test results):

I regularly listen to my pal's system wired up with more than $20,000 in Nordost cabling (he used to have my cast off speakers, too, in that system)  but my system sounds darned good to me!   And I think it's fair to say I'm a picky listener :-)
