Hi @jambaj0e
I don't have experience with TWL cables, but I have been using the NRG Custom - The 5 on a Class A/B SS amp, and a Class D amp, and it's smaller, thinner sibling the .1 on my DAC. I also have their speaker cables - the 6:6.
In my experience, (system, room, ears etc), I would say they/NRG cables are neutral, not warm. Dynamics-wise; no complaints here, at all.
