The ELROG 211 has a standard old fashioned "M" type filament, which you can see from their photos of on line, of the tube sans plate.The VAIC designed DHT filament, which is symmetrical, quite robust, with a larger cathode emitting area, seems to me to be a far more advanced tube design, intrinsically.
Notice how the EML extends their filament structure above and below the ENTIRE grid-plate interface. That is dramatically good design to my amateur eyes and my own way of looking at a tube.
Jac Music produces and markets the VAIC design today in their Emission Labs line of DHTs.
I wonder if the new ELROG 300B will have the same old-fashioned "M" shaped filament as their 211, or something more innovative ? It should be easy to beat a standard WE 300B. We will see, find out, soon enough. I wish all these tube guys well.

Almost cannot imagine they will be able to bring tears into my eyes as only the WE300B can...
But very curious to find out...

My original audio mentor, Robert W. Fulton ( 1925-1988 ) would never allow me to use a WE300B. He says, in his time, the best audio people knew not to use the tube. He was AMAZED in the 1980s, that members of the public would covet it !!!

At the end of the day its just another tube enabling great of poor results depending on how you use it.
I happen to love Audio Note E (HE) loudspeakers, and with 98dB you need 5-6 watts. I just don't have room or guts for horns, so this is what I have to look at at the output. I tried 2A3's, but power is simply too low.
Results also depends largely on how you drive the 300B. I see a LOT of 300B implementations using wimpy drivers. You really need a VT25 to drive these tubes at their best.
In my setup and on my speakers I get the naturalness of the 2A3, the midrange of the 300B and the pace and soundstage of a 211. I'm happy with that.
As friend and foe will agree upon, the ER-300B is actually no 300B at all. Its just another tube using the oppoints of the original WE 300B.
I'm looking forward to the results I can obtain from these :)
