I completely agree...there may be a slight difference in the level of buzz from panel to panel, but for the most part I think it's very subjective depending on the listener. In Standard ESM, I can hear my 500m buzz from the couch 10 feet away during quiet scenes...in ESM 2, it's barely audible. As far as losing brightness going from Standard to ESM 2, the difference is not even noticeable in Pure mode, to my eyes anyway (I can see the diff in Standard mode, but really, who cares...if I wanted it that bright I would have stuck to LCD). Easy decision, for me anyway to keep it in ESM 2...I am having it calibrated Friday and will probably have it done using the same setting.
Quick story - a friend of mine recently purchased the 500m as well. He hears NO buzz...I was over at his place last weekend so I sat 10 feet away with the same settings, and it sounded pretty darn identical to mine (slight buzz in Standard, no buzz in ESM 2). We live at altitude as well, so I would expect the buzz to be slightly louder anyway (though not as bad as a plasma from say 4-5 years ago).
IMO, it's 90% ears and maybe 10% buzz variation from panel to panel. In any event, to me it's a non-issue given the Kuro's PQ...there is no way I would sacrifice that to get rid of a minor irritant that comes with the technology (which is non-existent anyway in ESM 2)!
