Psvane 300-B Tubes ? ? ?

Takatsuki.

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?

Western Electric is supposed to reissue their own 300b "soon."

1makr,
Given what you’re seeking the New Psvane W.E.300b may be worth a try.
I also have the Frankenstein and would say that the Elrog and the Takatsuki have a"touch" (and only a touch) more organic character than the EML XLS. I must say however that no tube is perfect in all sonic/musical parameters and IMHO the EML is organic enough and just strikes me as very natural with virtually no editorializing.

It conveys warmth, bloom and authentic tonality along with excellent dynamics, authority and very balanced across the frequency range. Listening right now to Harold Land(tenor sax) Hampton Hawes (piano) and Jim Hall (guitar). Full bodied tone and very tactile/ palpable  aura.

If you do get the Psvanes I am very interested in your listening impressions. I suspect this is a very good 300b choice. Have you tried the Western Electric reissue 300b? I had a loaned pair a few years ago in the Frankenstein and didn’t care for them. They were too soft, laided back (lacked dynamics and vitality) and rolled off IMO. Maybe just not a good fit with the Frankenstein (or my ears). No doubt YMMV.
