Boy do I love a happy camper!
IMHO the Opticis does provide complete isolation from the Mac, and a USB cable does not - I proved this to my satisfaction pre-Brick and owning the Opticis never considered using anything else. I do have a Sprocket battery pack on it.
All that said, Gordon is a very smart guy and one of the few who will not say you don't need something to make his product seem complete.
FWIW he did tell me that he prefers the RCA Cleartops to the Telefunkens in the Brick - that will save you a buck or two if you are undecided about where to start.
Lossless has some significant advantages from a file management point of view since it provides a robust tagging environment which WAV and AIFF do not. Also a lot more reasonable to load on an iPod should you wish to etc. All but the most golden-eared EAC/FLAC/Foobaristas seem to be happy with the choice - but then they are dealing with PCs...
Steve at Empirical Audio did a comparison of some of the formats you might want to take a look at. Apple Lossless is like 2nd or 3rd.
