I only am saying what I have experience with. The TC was a bit of a change from the VS. It is the same wire, but with a different dielectric which also allows the TC to be braided in a more tight weave. The capacitance and reluctance specs are quite different between the two cables. It really changes the sound profile. The TC has much more prominent highs. I thought it almost too bright to begin with, but it became more neutral after a while.
I have never heard the speaker cable that Danny sells.
Cool deal. It's interesting to hear about the differences in cable.
On my SVS-Ultra Bookshelves, I had changed from zip-cord to Blue Jeans Cable 10-gauge Belden 5T00UP
https://www.bluejeanscable.com/store/speaker/index.htmI did notice a ~5% increase in clarity of high frequencies. I was surprised to hear a difference.
With the different cables you mention, I'm thinking that tuning can be done if I develop a preference for a sound change.
I just don't have it in me right now to spend much on cables yet.
That day may come though.
