Tou would have to contact John Curl--I'd suggest trying at Audio Asylum, he's a frequent contributor there. In the old days, it reputedly took a long time to get John to finish the upgrades; perhaps he's faster with turnaround now. The Vendetta was a work of art, one of the few components I sold that I should have kept, if only out of admiration of the design, designer and craftsmanship.
Vendetta phono stage upgrades
A question for the diehards. Does anybody know how to get an older Vendetta phono stage upgraded to current "D" status?
