hello A'goners, 
can anyone drop me the manufacturer brands using of ribbon or somewhat similar construction like foil in their cables? i have gather names like Verastarr (heavily marketed) & Omega Mikro, i tried google but nothing much come out. i'm trying to find out more brands which are unknown, rarely marketed by dealers.
kindly assist me by giving me names and i would try to audition the cables myself. 
Your contribution would be appreciated! Thank you.

If you live near Chicago I have Eric’s Impulse and Enchanter PC's. Not his latest design but very good. I also have his original Interlocker RCA IC's.
Pure Note Paragon Enhanced. No longer made. This 10 yr old silver ribbon IC is still in my system after extensive auditioning against respected newcomers. (Avoid the previous non-enhanced version.) Informative review here for a later model, TRS Audio Designer’s Edition.
Alpha-Core by Goertz no idea if they are still in business but their cables pop up on here from time to time.
