Wow. These little drivers really sing. I've always been shy of dynamic drivers having had "furniture" and bookshelf speakers most of my life. Historically, I maintain the rule-of-thumb that anything that tries to do a number of things well, usually ends up doing a mediocre job at best. The HD650 is (along with maybe Leathermans) an exception to that rule. Tonight's the first chance I've had to really drive these things. The Headstage Arrow's on GAIN III, FLACs are on the Cowon J3, and I'm spinning some damn respectable audiophile material. (Anawaty/Russell's, Monjour) I mentioned this earlier, but the bass sounds real to me. Authentic. No unwanted chassis (May I call it that?) resonance. I don't hear the veil. Everything is there where it should be and details are exquisitely rendered.
My perception of soundstage may, admittedly, be skewed. I haven't had a decent speaker system for a while. I'm not sure that's relevant though. This just sounds right to me. Like just-right porridge. Now that the cans and the ALO cables have approximately thirty hours on them, besides the obvious question, "Will they sound even better in time?" I have just one other question: are you kidding me?
