Ozzy,
I have a couple of thread going on this amp, but I decided instead to order Don Sachs Kootenay amp after hearing it in my system. It does everything my Platinum McCormack does... amazing LF control, but Don's amp is vastly more holographic. Lots of the better tube amps have this characteristic. It is a tall order for SS amps to perform similarly.
I am still eager to hear from someone who can comment on the sound of the Crimson in their system.
