James,
I have one more question for potential upgrades to 9B-SST amplifiers. I know you have said in the past that it is not economical to upgrade, but 9B-SST is modular in design and could be dismantled easily? Also, Bryston provides upgrades from 9B-ST to 9B-SST, so SST to SST^2 would just continue this tradition...
As you can tell, I am trying to stay current with Bryston product lines...
Ciao,
Luigi
