hi, I wish there were and maybe something could be done about starting one. I am the guy who's built the monoblock circlotrons with 3X3-6550s in the output stage and I think I'd be able to compete. I'm in the midwest though. plus, I would need to get the high impedance systems going for any demo, but sounds fine on my modified bose 901's wired in series, with two 18" subs tied in with high impedance low passes. Also have three ribbon tweeters per side, on top of the boses. A special set of 250ohm to 8ohm transformers could be made up for max power, but I'm going for an OTL topology, so raising speaker system impedance is the way to go...What have you got? I visited to washinton state area about 7 years ago and loved it.... If the whole event could be made totally trustworthy, with bonded personel working the contest, perhaps amps could be mailed in, and uncrated , judged, then re-shipped back to owners. They would have to be ear tested with matching or same speakers of course (with power,distortion and freq. sweep equip. as final testing)...with a small entry fee to defray costs of contest....perhaps the management personel of DIY could be such individuals..??...midmoe
