Spritzer, I'm guessing Mike hasn't had time to try out tubes since he's only had the BH for a few days.
I, too, liked the Jade, which I think would be a nice complement to the O2s. I didn't really do any critical listening, only enough to confirm I didn't much like the 4070s and HE60s, and preferred the Jade to them, but still preferred the O2 to all.
