Well, I owned rougue Mono's great amps, They even sent me a pair of their highest end input tubes they can supply for these amps within 3 days of asking about them for 20$ and the retail is like 55 each from any other dealer, great customer service and responce, I think that it was possible that the ISP or provider of their email service was down for a while or something when tire guy tried to contact, maybe they were on vacation, it could have been simple human error WHO KNOWS!!! who cares just don't slam a company for that (well except maybe audio research which I have heard TRUE horror stories about.)
