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

In my experience EAT and Takatsuki are the best 300b tubes at the moment

At the risk of further complicating the issue: while both Takatsuki and EAT comfortably beat my TJ Full Music meshplates, in my Wavac EC300b there is a strong effect dependent on the recifier tube used. While the EATs prefer to be driven by Tungsol KT66s, the Takatsukis love to be driven by the cryo version of Svetlana Winged Cs. I have experimented with a large range of other 6L6GCs such as JAN Philips 7581-as, Shuguang coke bottles, Tungsols et al but the above combinations win out. The EAT/KT66 combo has better dynamic range for the price of slightly harsher sound, the Takatsuki/Winged Cs major on resolution and timbre for the price of somewhat lesser ooomph. In the world of tubes, trial and error is indispensible
