Revelation Audio Lab (RAL) sells all kinds of cables on Audiogon. I ordered a pair of cable for HD6x0 back in 9/25/2007 but never got it. Several emails to Brad Vorjtech, the point person of RAL and I'm told to wait. Then since last month, Dec. 2007, they stop replying emails and completely disappeared!!!! I went back to Audiogon to check their userid "Vtech2000", Viola, it shows "No longer a registered user. This account was either cancelled by the owner, or suspended by Audiogon." Mostly likely they have been suspended because of their shaddy business practice. A lesson learned.
