But, the thing is this: sure, it's got 24/96 capability but not a lot of stuff is in that realm. I take that as a minor consideration. Word clock: who cares? If you have a DAC that properly re-clocks and does away with jitter, like the Lavry Blue or DA10, then you don't need or care about

I would imagine the Transporter merits a "class A" -- if it doesn't get it, then something is wrong. Let's see: state of the art DAC (can't wait for comparisons) and bit-perfect transport. As for the Class D thing, well, that's just snobbery. The SB is better than CD players costing far more.
