Is a shielded toroid preferable sonically to an unshielded one for a Pass F4, F5, etc.?
If so, who manufactures them, preferably without a major lead time? Not finding anything on Digikey, Antek, Mouser, Newark websites ...

Can't answer the first question.
What type of shield? Antek AS series are used quite a bit for the amps you listed, and the common ones (AS-3218 and AS-4218) seem to be in stock at the moment.
