@gochurchgo ...My fear with passives is sounding thin...
I own an Axiom II passive and I understand your comment. In my experience, ever, a thin sound could reflect how the sound of your source is is playing nice, or not, with the rest of your setup..
FWIW, as I improved my transport and DAC, the Axiom II sounded better. I plug it in occassionally and listen for a few days and then switch back to tubes. Just like the texture and body I get with tubes.
