So I've received my PS Audio GCHA. All I can say is wow. I've been playing with it for a few days now. My only problem right now is a slight amount of sibilance with my k701s; although this seems to be diminishing. Thus far this amp works incredibly well with any of my cans at any volume. There is a tremendous amount of detail still available even at very low levels. It also happens to make my 650s sing. The amp is without a doubt solid state, but it is very liquid while still maintaining a high level of detail.
