Anyone listen to Zu Audio's Definition Mk3?

"The absolute best IMO the Takatsuki TA-300b(japan) very expensive(1800 USD) but elevates the Franks to the truly sublime tier, just superb.”

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?

Sorry Zu owners for the 300b tube discussion but I just had to respond to morgan`s earlier post. Morgan the EML mesh is considered excellent and upper tier(I hav`nt heard it myself). The Psvane is said to be a bit better than the Black Treasure version(so it`s very good). Havent bothered with the 6EM7 at all.Phaelon is right, the premium 300b tubes are worth the cost.
Regards,

Morgan, The Psvane MkII is the grey colored tube? How do you like it? I haven't been able to find much info on the Grey MkIIs, nor many sellers of the MkIIs.

Roscoe: No it's the black version..... And I've only played them for a few hours, so I don't have many impressions yet, other than they sound good so far:). To my eyes they do look smaller than the prior Shuguang Black Treasures that I had.....maybe I'll start a different thread for this discussion......sorry for the distraction guys......
