Psvane 300-B Tubes ? ? ?

Does anyone out there have any experience with Psvane 300-B MKII or their WE300-B Replica tubes ?  

I found the best sound from initially the Sophia Princess mesh-plate 300-B's, then their Royal Princess 300-B's however I'm definitely NOT happy with their reliability, especially the Royal Princess !  
I had a mesh-plate from new have a glowing spot on the mesh-plate, and they told me it was from sitting on the shelf for over a year !  REALLY ! ? ! ?  And I had two Royal Princess tubes go out with less than 600-hours on them, unfortunately well-past 1-yr. warranty.  Left a bad taste...  I'm NOT going back...  
I've tried EH gold-grid 300-B's, Gold-Lion's, JJ's...  All sound somewhat different but the Sophias sounded the best, however in my experience, reliability is questionable...  Thanks...  John

@liquidsound heard the Emission-Labs 300-B (not the XLS variant) and they sound good however not as good (in my opinion) as my Sophia Princess mesh-plates tubes. 

Sorry I'm not clear, are you referring to to the Emission-Labs 300b solid plates in your comparison and is it the pricier Royal Princess or the similar priced Sophia princess mesh you compared against eachother. I ask because I use the solid plates but I've been curious about the punched metal "mesh" of  Sophia mid priced 300b. Thanks

I'm still using the Sophia mesh-plates.  I gave up on the Royal Princess a good while ago.  I am looking for a good replacement for the Princess mesh-plates.  I have heard the Emission-Labs solid plates, not the mesh.  The sound is good but notably different than the Sophia mesh plates.  If I can find a 300-B tube that sounds like the Sophia mesh-plates or the Royal Princess, that would be great.  No more Sophia tubes for me !

I use the Psvane WE300B on good quality SET amps, and I very very very highly recommend them. Nothing to criticize at all; the mids and highs are just the best i have ever heard. The only tubes that may beat them, and I also use them on another system so I know what I am talking about, are the famous and highly expensive Takatsuki TA300B, that output more bass but less glorious mids and highs. It will depend in fact on the nature of your speakers and/or your preferences. For your reference and comparison, the amps using the Psvane WE300B are the Coincident Frankenstein 300B MkII. The tubes you are using are known for being unreliable.

A little late to the game hear, but I was looking more into these Psvane WE300b tubes mentioned on this thread, and interestingly enough, I found that there is a newer, recently updated version of these tubes, now known as the Psvane WE300b-PLUS version. Anyone know anything about these???

I really like my EML 300b-XLS in the Coincident Frank mkIIs, but I would love to have a touch more midrange naturalness and bloom without losing the soundstage, detail, and dynamics of the EML. I really like the Sophia Carbon Princess' midrange, but it really lacks the soundstage depth of the EML. Besides the uber $$ Taks, Elrogs, etc. what other options are there out there, and yes, reliability is important?
