What 300B tubes are you using in your VAC amps?

I am interested in the KR 300B's vs Sophia carbon plates and also the Full music brand but I think there the same as the Sophia. Any feedback on these?

I also have the VAC Ren. Sig. Mk. III 140's & tried very hard to find 16 Golden Dragon 300B tubes.
After about 5 months of only finding a total of 4 NOS Golden Dragons - I opted for 2 matched octet sets of WE 300B's @ $5,800 ($10K List) & am much more than satisfied.
I think the KR 300B's should work very well & would love to hear the final results from you.
BTW - KH @ VAC now sells his own brand of 300B's @ $370 per pair.

Paladin.....even though I would like to purchase the WE's 6K is a bit much for me...more than I gave for the 140's in fact. I would like to hear thoughts on the KR's and other brands for the VAC's
I had the GD's and Cetrons in my 70/70 and the dragons were much better....I liked the Holographic soundstage and itamcy they projected. I purchased a octet of Sophia carbon plates and they were wonderful with a very lush midrange and very musical bass the plenty of punch. I have yet to hear them with my upgraded Accuphase C200 preamp and I think the transperency should improve greatly. I am sending the 7070 to kevin to upgrade....so I will use the 140's and will be looking to purchase 8 Sophia's or 16 of another brand.
BTW what do you like about the WE's and are they new production. I might be tempted.

What's the matter with using Electroharmonix Gold Grids?
Is it because they cost so much less than all the others or are they audibly inferior?
I have to tell you that I run eight of them in my Canary 339 amp (also a push pull 300B triode amp like the VAC) and I love them. Never felt the urge to upgrade them. I did find that using NOS 6sn7's as the input/driver tues did make a nice diff. over the stock EH tubes, however.
