LinLai WE 300B or the LinLai Global Elite Permaloy 300B tubes ?

I would be curious if there is a complete list of available 300b tubes. The number is overwhelming when it comes to making a decision, and the number seems to grow every year. My top two are Takatsuki and KR balloons. Has anyone heard the AudioNote 4300e?

The 5 year warranty for the WE-300b is crazy. Not even the Japanese offer anything close. 

I have an Ancient Audio custom 300b SET. It uses two 300b and two ECC88. I tried BlackTreasure, Sophia Royal Princess, Takatsuki, and KR Globes - in that order - each representing an improvement in sound quality. I loved the Takatsuki (simply sublime), but experienced reliability issues; and unlike Charles' experience, I was less than happy with the company - especially considering the cost. The KR Globes kept most of the Takatsuki sound quality, but were more dynamic. I would love to try the AudioNote 4300e (made by Psvane, I believe) or the WE reissues, but otherwise plan to stay will the KR Globes. Most recently, I upgraded the ECC88 to Telefunken and was surprised by the improvement.

BTW. .  .back to the discussion about 300b tubes. . . Recognizing that there is some rebranding, I count 23 manufacturers of 300b tubes, each with as many as 4 different varieties.
