Jimmy, tell me what you liked about the SA-10? I understand you need the digital input so this sort of ruled this player out for you, but you commented that you really liked it. What did you like about it?
FWIW, while I think the B&W speakers you run are excellent speakers, I find that they are somewhat forgiving in the sense that they make other changes in equipment etc. . . less apparent. I used to own B&W speakers and found that they are very good, but did not exhibit as noticeable of a change when I would swap out other components (as compared to other speakers I have owned). Based on this, my feeling is that you must audition any new equipment through B&W speakers (preferably your own system) and decide from there. This "kind" nature of the B&W speakers, in my opinion, negates overspending on other components and cables as improvements by such changes are not as significant.
