Favorite 300B: Sophia vs KR

I just can`t seem to shut up on this thread.
Gsm I`ve been eagerly awaiting your impressions,thanks a lot. Gsm you reminded me that I have`nt mention what music I use, I`m an absolute jazz nut(and seemto be getting worse).A friend and I reccently went to a local jazz club to see the young and 'very' talented guitarist Randy Napoleon who played with a sextet, beautiful music and up close sound(our table was next to the stage).These encounters always expose the full body and tone of these beautiful sounding instruments(lean,thin, edgy,nervous and clinical just are`nt present, nor bloated, flabby and slow)

I`ve been attending jazz venues frequently for the past 22 years and it`s a wonderful time and what training for the ears!
As a result of the ferequent exposure to the acoustic instruments and vocalists it seems when I listen to a system I can (it seems) sense/hear the artificial or canned sound of what some would considered high end- audiophile presentation. I`m in no way suggesting my hearing or taste is better than anyone else at all, just trying to explain my bias for context.

My bias is heavily toward the organic,holistic tone,timbre and overtones of music with natural dynamic ebb and flow.
My praise of the RP and Takatsuki centers on their exceptional ability to sound so natural and like real performances are present.They both push me closer to what I hear and also feel at the live jazz venues.
This is my point of reference,so those who share similar a orientation my high appreciation for these two 300b tubes will probably make some sense I hope.

I would also like to thank you for all your learning experiences and want to thank those who commented on my two cents. I will mention I like a lot of various female jazz such as Jennifer Warnes, Hollie Cole, Diana Krall, Melody Gardot, and Patricia Barber among others. On the male side I listen to many of the stunning recordings on the German Stockfisch label. To really find the soundstage I listen to classical and live recorded Russian choral music that are well recorded.

For the past 3-4 years I have been listening to 45 tube amps. (Jeff Korneff and Yamamoto A08S) because I firmly believed that a 45 tube (on the proper matched speakers) had the most natural tone and timbral accuracy of any of the triodes and in ways they are king at low listening volumes with limited power reserves.

However I am happy to conclude that the RP and Takasuki tubes sound much the same as a good 45 only on steroids. This is as high of complement as you can pay IMO.

What you get here is pure music and no areas to really criticize. In a properly designed amplifier these tubes are very tonally accurate and simply make the speakers disappear with ease. Not much else I can add except I wished they were not so darn expensive as my entire stash of 45's (7 pairs of NOS) were about the price of one pair of these 300b's. Whoever said being on steroids was cheap!

Gwalt,
I agree with every thing you you wrote above 100%. An excellent and clear summation of these two tubes.Well done!

I agree with your findings also Charles1dad and thanks for all of the time you have put into this thread. Now that we have praised both of these tubes (and the truth be known) I wonder how the sales will drive the prices?

I received my Takatsuki's late yesterday and they are warming up in my Frankenstein amps now. Right out of the box, I,m hearing profound differences from the previous Black Bottles. I can tell that they take the Franks to a new level. I'll report more as things progress. I was able to purchase a lightly used pair of Black Bottles to go with the 2 from the Franks and I will install them in the VAC 30/30. Should be interesting
