the pic of the speaker with the top cover off... couldn't tell if my eyes were playing tricks on me or not... looked like there were multiple compression drivers in that stash...
and... I really liked your choice of wood for the chassis and what appears to be a brass top plate. Even our competitor's tranneys looked good on your amp.
man... them russian teflons do eat up some space though, heh?
the exo-100's are going to look lost on your chassis... perhaps you need some of the dowdy chokes to fill the empty top spaces and plate choke load your 801... only other thought is that you may want to increase your blocking cap from 2.2 mfd to something larger in say the 4 to 6 mfd range. You could experiment and scope out the differences.
