I spent the extra money for the Ref 30 because I was under the impression that there would be periodical upgrades to firmware as well as other upgrade options. (Don't get me wrong...I also spent the money because I love the way it sounds...)BUT! Where are all these upgrades? There's a firewire port back there...will I ever be able to use it? What about DPLII? If I missed the big announcement to all thier loyal customers about the upgrades available then shame on me. C'mon....there can't be THAT many people spending almost 3K on a pre/pro! I'm sure they are small and short on staff...but I've sent many e-mails asking about upgrades and never gotten a response...makes me wonder if I shouldn't have gone with the Anthem.
