I have both so here is my take. The BAT in the 6922/6dj8 has more of a honey glow to the music than the Cary. The Cary has more detail and more deep low end extension. I would say that perhaps the best description is the BAT has what I would call the classic tube sound of the 60's, while the Cary sounds like you went thru a 60's unit and updated caps, resistors and other parts. Email me if you need to know more.
