The CJ CAV-50 is a wonderful, sweet little integrated amp. As you suspect, however, it is not a good match for the B&W 804s. If you love your speakers you will need a new amp, and that probably means SS to mate well with the 804s. What kind of music do you listen to?
But before you do that I would try your CAV-50 with a pair of more efficient speakers. I would suggest something in the JM Reynauds or Triangle line, but there are lots of options. I recently heard your amp played through a pair of Tekton speakers and it was very good. I think that you will be pleasantly surprised.
