After wanting them for a very long time, I'm now currently awaiting a pair of Coincident Frankenstein MKII's to appear for sale in Audiogon, or one of the other used audio sites online. Sadly, a serious family medical emergency that thankfully ended well, took me out of the loop for a few months (late December through mid March) and I just missed out on at least four that I would have snatched up instantly. Now its just a question of waiting. The only currently available option is is a pair of MKIII's being offered in a forum, whose owner has an extremely overpriced opinion on what they are worth. And while a MKIII would certainly be optimal, given the average prices for the MKII's, it would be hard to pas on one of those. Hopefully a pair in excellent condition appear soon.
Thanks to everyone who has contributed to this discussion as you have provided invaluable insight into tube options for the Franks, which I was searching for, and truly appreciate. It is good to see some notable online audio forum contributors perspectives, in particular. Thanks especially to Charles1dad for your always well considered, insightful and kind thoughts which I have greatly enjoyed over the years in various discussions. And in this instance, on the Franks, in general, and your extensive tube experiences. I hope to be joining you as an owner soon.
