I do not get how we got from speaker cables theory so far...like on my thread How to select a good Speaker Cable
it is all about objecting a subject no one tried, but extensively argued.
It may explain a toddler who rejects a food even he didn't try it, just because.
The unfortunate truth is, that none of those who object the idea (connection between Amp's DF and cable's resistance) do not have an alternative. This thread do offer something, but it is far away from physics, as west from east.
