Interconnects: solid or hollow core wire?

Hmmm, I thought Supra used hollow core wire but they just confirmed that the wires are wrapped around an hollow tube of PE. Their literature is vague about it. It seems to suggest they use hollow wire... a new one on me, too, hence the question!

A good compromise is bubble core. Electrons love a good bubble bath.

I'd like to hear from the electrons themselves, please, about whether they like a good bubble bath or not.

Solid Core ICs and speaker cables by Mapleshade or Audioquest. Two very different price points and design approaches but Mapleshade is the best cable bargain in existence.

Stevecham, you haven't tried them all.
