Coincident Frankenstein mk.2 amps

I think all the tubes you're considering are a good match, but they also will change the sound in different ways. If you want a bit more of a mellow, vintage sound, then try the psvane, if you want more frequency extension and imaging precision, try the eml.  And ideally, try them both.

One caveat is that both Charles and I have tried both tubes and settled on the eml. In my experience, Charles has good ears and makes great recommendations. We also had similar speakers though (coincident super/total eclipses).

I have been tormented over this decision for months now.  EML XLS, Elrog, Psvane Acme or ?.  Israel has been right every time so far, so I am taking his advice.  I am ordering a pair of Acmes.  He claims they are the best for the Franks.  I will report back!

Interested to hear the result

Hi tswisla,
The Truth of the matter is that there’re no bad choices on your list as all are excellent options. Each of them will have their positive attributes and distinct signature. I believe that you’ll be very happy with the Psvane Acme but I also believe that you’d be very happy with any of them.


It’s good to have such wonderful choices available for the superb Frankenstein mono blocks, Congratulations on your selection and I look forward to your listening impressions. It’s good to know that the Frankenstein and Zu Soul Supremes pairing is so successful for you.

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.
