Oh for fuck's sake, I think I'm done with Grado. Mine sound way different than the ones I heard in Singapore, and I have let them play several hours. It serves me right for sending my electrostats home after the flooding. I already have some 404's, HE 60's, and 4070's out here again. I had to buy a cheap SRM 006 to drive them that hasn't arrived. I will probably get Justin's BHSE out here just in time for another flood......... The only conventional headphones I have that are worth a shit are the HD 800's with an uber-expensive Stefan Audio Art cable (really worth it).
