....I'll more likely stay away from the Postmaster 33 terminal and opt for the other spade on an authentic pair of used Kimber 8tc or 12tc. Beside's, no one here has confirmed they fit the 4BSST2 binding posts.
From Kimber and vhaudio.com websites, Postmaster 33 and Wbt 0681 spades are in same size 5/16" My wbt 0681 spades connected well with the 7B-SST2. I suppose Bryston use same binding posts for 4B-SST2 as well.
