I don't know how they compare to the new Cam-400's, but I did live with CAM-350's for well over a year.
I think that those amplifiers have great impact and have a smooth musical sound with very good resolution.
They definetely do not image as well as some other amplifiers.
I used them with Dunlavy SC-V's, Vandersteen 3A Signatures, 3A Signatures with Subs, and Vandersteen 5's.
I eventually had to upgrade them, because they were not giving me the imaging that I wanted, and they had a signature that I grew to dislike.
I moved to Audio Research amplifiers after those.
Sorry I can't help with comparisons to the current CAM-400.
