Bryston makes only two preamps: the BP20 and BP25. The difference in model #s has to do with how it's configured - with phono stage, remote, line stage only, etc.
But they do not make any such beast (2.2) that I'm aware of. Tale a peek at their website: www.bryston.ca. It's well laid out and will give you all the info you could want.
