Crumbs, John, that's a poor show. As it happens, I've been buying Autocar since I was ten (yes, 10) but often found the forum pretty naff. Maybe WHF and Gramophone should merge fora, as theirs could do with a bit of excitement!
Well, as luck would have it I had both the SM6 and an ND5XS in the house together for a couple of weeks. I found the Naim a little bit better sounding, but would find it extremely hard to justfiy the additional expense unless I absolutely needed:
Not true - I'd have to check the exact specs because I think it differs between wireless, wired and USB but I can certainly play 24/96 over wireless.
Seen your sig now, thanks, and I don't think the SM6 would be out of place, but since you have the Caiman might you consider something a bit cheaper? Or would you get rid of the Beresford and use the Cambridge for DAC duties?
No, it'll do 24/96 over UPnP (though they recommend wired for high res, though it works OK for me on wireless), and 24/192 over USB (if you use the specific driver they provide).
