Maxmad,
I can say that I would never recommend matching Sophia mesh (really, perforated) plate 300Bs with Cary amps. That's doubling down on the same basic sonic aberration. If someone likes that combination, one can't argue with that, but it would be a piling on of the same euphonic colorations that obscure what you value.
I have a pair of KR VV302 Blue glass that sound beautiful and bell-like in some amps, yet hard and overbearing in others. I also have the older KR Enterprises straight tube 300B with the AVVT-like interior structure. Those tubes have strong, vivid transient clarity, probably the firmest bass of any 300B I have, and good top and bottom extension. But in amps I've used them in, their spatial presentation is great in height and width but cmparatively limited in depth. I'm aware of the Takatsuki but haven't tried/heard them yet.
The Shuguang Treasure 300B has been unfailingly good in every amp I've heard them in, albeit a more modern sound than the typically vintage mesh plates. The current production KR AUdio balloon glass 300B nicely resolves a lot of the spikey differences between all these tubes. For me, a polar graph of its relevant sonic attributes is close to a circle in most amps. My mesh plates sound sensational in my re-capped Audion monoblocks, but I consider that a highly-specific match arrived at by chance since they didn't happen to be in the amp when the caps were chosen and installed.
I will say the Sophias were much less expensive when I bought them. But so were KRs. About $900/pr. now for the KR Audio 300B in the US. Partly a result of the dollar's slide and partly result of that company and its distribution chain realizing they had to own up to the true costs of running a business. In all this discussion, interesting that this decade's production of the WE 300B isn't in the mix.
Phil
