I've been wondering the same thing. The last issue I received was Winter 2001 - with Talon Khorus on cover. I've tried to find out what was up from them but no response.
What's Up Wth Ultimate Audio Magazine ?
They still have a working number but only v/mail which is never answered. Same routine with email. Are they out of business,on the ropes or what ? BTW they also renewed my subscription without permission and charged my c/card. Not happy at all about that. Yes, I have disputed charge.
