Vac isn't such an old company, but i suppose you can call 3 year old VaC's "vintage". "Vac" , my opinion, makes THE best tube amp's in US of A. Some of the leading HI end co. "mate" their products with VAC. Wadia, Avalon...etc. For "Underhill", you are on the right track...Right SeT, and right "horns" are just "magical".If you want some "info" on SET mach-up and "horn's" contact Torsten Loesch,TNT mag. contributing writer or Jan Hedlund at The Hedlund Horn http://www.vt52.com/diy_archive/diypage/hedlund/hedlund.html to see some of the best "horn" designs.
