Anyone listen to Zu Audio's Definition Mk3?

Not to divert the thread, but those of you who use 300b amps, should check out the Takatsuki 300b tubes that are made in Japan. Pricey, but amazing.

One other comment based on Phil's obervation about break-in. . . . in my experience, the Def 4s continue to evolve in a positive direction for months . . . even though they undergo prolonged factory break-in before shipping.

I`d think the Melody AN 211 and the Coincident Frankenstein are going to sound quite different from each other,yet both would likely be excellent and special in their own way. That would be a very interesting comparision with the Zu DEF speakers.No loser in this match.I have`nt heard the Melody 211SET but I`d bet it`s fanstastic.

Morganc, what 300b tube are you using? I`ve had my Franks for over 3 years and have used EH Golden Grid(ok) Western Electric re-issue(just ok) Black Treasure,(very good) Sophia Royal Princess(excellent!). The absolute best IMO the Takatsuki TA-300b(japan) very expensive(1800 USD) but elevates the Franks to the truly sublime tier, just superb.This amp runs the 300b 'very conservatively' and will extend the life of the expensive tubes. Just something to consider.You`ll hear every bit of this superior tube with your transparent Frankenstein.The Sophia Royal Princess is close to the Takatsuki`s performance and better than the other tubes mentioned above.

Funny, you must have replied to morgan`s post just before I did. We had the same thought about the Takatsuki tubes.O f course I agree with you.

I just want to ad my voice to Charles1dad and GSM18439 concerning the top tier 300b tubes on the market. If you have a 300b tube amp, I can’t urge you strongly enough to set aside your disappointments with all the overblown hype that you’ve heard used time and time again to promote audio products, and give these a try. I haven’t heard the Takatsuki’s yet but if I had, before I invested in the Sophia Royal Princesses, I’d probably be a member of the choir. It's very easy for me to imaging preferring a modest amplifier with these tubes than a significantly more expensive amplifier with more commonplace tubes. The difference is that profound.

I am comparing at present a pair of EML Mesh 300's to the Psvane 300 mkii. Both are sounding excellent in my current system. I would love to hear a pair of the Japanese Yakatsuki's! Maybe a Christmas gift to self :)?

BTW any of you guys with the Franks: Have you rolled the 6EM7 or 5u4g tubes?
