You really need to be patient with this one. Because of it`s size, the small caps needs to be fully charged before it sings. I would estimate they need 100 to 200 hours. But when accomplished, things starts to happen.    Brand new out of the box, it sounds thin, with no bass to speak of, When run in, the midrange is fleshed out, and there are bass a plenty. If it is present in the recordings, that is. A lot of 70`s recordings are revealed as having not much bass, It`s just the neutrality of it, that is showing this. Not a fault. With "normal"...
