300B Tubes - Which is Best?

Can't find anything addressing this on site so, here we go! What is your favorite 300B SET tube and why? What source do you use for these little treasures? What experience has anyone had with the Sophias, sound and company who sells them? Any thoughts on Western Electrics and that strange blue glow? Maybe they aren't as vacated of gases as some others? Anything new out there? Thanks, people.
Stereophile did a comparison of 300B tubes a while back. It is archived on their web site.
I like the WE ones. They were moving recently and setting up a new production line somewhere down south, so supply of them is hard to find at the moment - maybe sold out temporarily. They set the standard in this tube and have been doing so for 60+ years.

40,000 hours is fairly unrealistically optimistic. A lot depends on the amp, but even driven at low power, it's not likely to get 40,000 hours out of a set, despite the 'myth' about that. Guaranteed they will be pretty spent even @ half that usage. Tubes just dont' last that long, esp. power tubes. (think: that's 8 hours a day for 13-14 years straight. No....just not realistic)

They made the 'old' version up until 1989, then stopped, thinking there was no more market. They brought the line back up some years later, in the 90s... I don't think it took them 5 years just to restart the line (though they are notoriously slow, re: product developement) - most of the tooling and some of the workers are originals from the old production. There's tons of good info on this @ their site, www.westernelectric.com

Can anyone give me their experiences with the Sophias as regards music making ability, reliability, and the company who sells them in the U.S.? Thanks, guys.
Dear Tomryan:

We are in Washington, DC area. Check out www.sophiaelectric.com or call me at 703-204-1429

It may be an old thread but I will continue it. I have used the Westerns, the TJ mesh plate regular, and the newer Sovetek. All are very good and very reliable. The newer Sovtek's are in the same sound line as the WEs. I am very impressed by them. A WE may be better, but mine always had some harmonic problems which WE failed to verify. The TJs, like the Sophias are excellent and have good bass. All are subject to your ears. I use mine in Cary 805c Anniversary amps with Quad 988 speakers. The detail of the speakers seem to lend themselves to mesh plates. I have yet to try the new Valve Art or the better TJs / Shphias and would like to.
