I think there should not be much problem with the brightness, there was one opinion with a bhse: "I see a long weekend coming... First impressions - one should send this package to Audez'e to show them how to ship a headphone And - forget the idea that BHSE and SR-009 might not work - it's a fabulous combination Coming from the O2, one starts turning the head left and right to "see" the whole stage - what used to be a (although very precise) small picture is now everywhere, all around... The 009 is brighter than the O2, but not as "glaring" as the HE60 - so it's exactly what I hoped it would be... lots and lots of perfectly defined bass, good voices, lots of details turning up one didn't notice before, no sibiliance... But not picky, even bootlegs that are pretty much unlistenable to on the O2 sound pretty good on the 009. Sorry that I don't have all the lingo down yet - but take my word, this is a fantastic combo "
