Favorite 300B: Sophia vs KR

I am currently using the new Sophia Royal Princess 300B tubes in my Woo Audio WA5LE. Wow, what a tube. I have compared it to WE, Sophia Mesh, Sophia Carbonplate, Shuguang Treasure, and EML Mesh. It tops all of them. Yes, it is pricey. I think it is the best currently available.

Rgurney, Would you elaborate a bit on the Royal Princesse's improvement over the Carbon Princess? The Carbon Princesse's have so thoroughly trounced my Golden Dragons that comparison seems silly. In addition to the improvements that I was expecting in detail, dynamics and extension, there is better separation of instruments in a more believable space. Voices are striking in their naturalness. I live within walking distance of a small club that regularly features Patricia Barber, so I always use her CDs as a reference. Until now, I've been convinced that her CD's were on the dark side of neutral. Now, they sound so much closer to the real Patricia. Same for Keith Jarrett, who I try to hear whenever he's in town. There are many great 300b tubes that I haven't heard, so I'm really intrigued by the new Royals.

Phaelon - The Sophia Electric website posts some helpful User Reviews/Feedback for each type of Princess. I agree with their assessments. Depending on your system and your musical tastes, a particular kind of 300B(mesh vs. carbon plate) may be used to better advantage than the other. The new Royal Princess somehow seems to magically combine the strengths of each kind of Princess - Mesh and Carbon.I say 'magically' because from outward appearances, the tube looks like a Carbon. Yet it has more of the air and extension of the Mesh, while keeping the dynamics and naturalness of the Carbon, with perhaps an intermediate seating position in the hall.
I've tried all the 300B tubes except EAT and this is the best for me.

Rgurney: NOS or current production WE 300B? And EML,..etc are less then half the cost of Royal Princess so I hope it's twice as good sounding. I would have tried the EML and KR were it not for Sophia Carbon. Still may some time in the future.

@Rgurney

From the info I got from jacmusic.com EML 300B Mesh arent direct replacement of general 300B tube. Are your Woo modded or something?
