Coincident Dragon MK I vs MK II

I would love to hear an all Coincident system. I'm sure the system synergy adds to it. I live in Ashland, Oregon so I'm going to have to miss the New York show.

I got the Sophia Electric Carbon 300B tubes from a friend and plan to give them a whirl tomorrow.

Erndog,
If you don't mind, let us know the results with these different 300b as driver tubes.
Regards,

Shoot, one of the Sophias created a flash, a pop, then made this screeching sound out of the speakers. I quickly turned the amp off. This has happened before with previous tube gear and It always scares the crap out of me. So it's obviously a dead tube :(
