hi all, i was wondering if any one else had to send their ref 50 back to b&k for a controller card and a software update. (under warranty of course) the people at b&k that i delt with we very professional, and the turn around was 2 days now thats service. my unit was 3 weeks old and the system locked up several times while i was setting up my room . when i called b&k they asked me for the serial number and version on the unit. i was then informed it was a first run unit, ( nothing wrong with it but had to be updated). it seems the 1st run software version is 1.0 and now its 1.4 along with a new controller card. im going to hook it up this weekend and fine tune my room. so far i like the features and preformance of it. i am running it with a ati 2505 5 channel amp (250 x 5). well i keep you all posted with my progress. frank.
