Received mine yesterday -- faster than anticipated.
Initial impressions are good with the SACDMods-modded Denon/Singlepower Supra++. Nice, noneventful frequency response, great isolation. I would have to agree that at a little over US$100 (I think mine was US$130-ish when all was said and done), it is the best closed headphone near its price range. Doesn't outshine the VTG, however (but we're talking the next step up at that point).
