the air dielectric


I don't know what the first company was that used a nearly 100% air dielectric in their cables.  Slinkylinks appears to have been doing this all of 20 years ago.  These days, Inakustik stands out to me for the explicitness and full depiction of their careful internal construction.  Something that Skogrand doesn't do.  At the more inexpensive end of the scale, Black Cat Coppertone Flatwave has found a way of implementing this nearly as well but with a lot lower manufacturing costs.

Other brands claim an air dielectric (e.g. DH Labs) but I have yet to see photographic proof.

Who else is really using an air dielectric these days?

This was 15-20 years ago, Not sure Tara making them now. Cost in the 15K range. Vaccum  had to be refreshed every so often. Probably stopped making (for general public) due to PITA factor and lack of demand. 
The electrons are obfuscating the detail in my music! I need more air in my cables!
