Well, ADATs don't click as a matter of fact. proTools doesn't click as
well! (at least I didn't have any clicks in my studio).
Maybe this is due to having it implemented in DSPs, instead of
"allround"-chips ???
There isn't a delay in the analog signal as you rightly guessed.
If you have digital input you can punchinout as well without clicks
(well, I'm in the fortunate position of having a gigantic digital console
to work on ;-) that does all the converting and syncing).
sounds like a hairy thing to solve, but:
As far as I know proTools is the only DAW that doesn't (at least not
audibly) click while punching inout. All the other native versions do
click! and nobody really cares, as long as it doesn't click in the final
recording!

jupp.! definitely, although I'd really like the feature....
