I have been considering the TH900 to pair with my ECBA. I am concerned, however, with tales of abrasive treble. Can anyone comment on this? I am EXTREMELY sensitive to glare, grain or etch (I like LCD2 v 1's and LCD3's). My LCD3's don't seem to be the best fit with this amp and am considering changing 1 or the other. I can't seem to come up with a good headphone to pair with the BA.
