I hate to say it but those cables for $100 and $79 are going to be junk, the best cables for audio and this has been proven for 50 years now is OCC single crystal wire and it's not cheap but if you hear it compared to all the other ofc stuff on the market including the real expensive stuff that's a rip-off the OCC is the clear winner, the ofc stuff is not even in the same league.
How accurate are cable descriptions for your system?
Steve Huff, whose videos I typically like on YouTube is now reporting this about some cables:
SVS Ultra Cables can be found at Amazon for just about $100 for an 8 foot pair. These will bring a bit more bass to your sound but are less refined.
Tuneful cables are light and have a nice design. They are leaner, and faster but also very good. You can find them for $79 for a 12 foot pair at Amazon HERE.
QUESTION: To what degree can his descriptions be taken as "likely true" for any given (sufficiently resolving) system?
I ask this for people who have found that cables DO make a difference (to their ears, in their system) and deniers will be ignored.
