2019 300B tubes that are worth the money?

but the midrange is magical with Voxatix speakers

~~~~~~~~~~~~~~~~~~~~

I just listened to 2 YT uploads on the Vox Pi. Honestly, I dont like the mids in this speaker. Its too forward * loud* in certain fq peaks. See this is why I draw my limit on sens at 95db, not a single db higher.  When a FR driver passes the 95db mark, the speaker gets into trouble with certain cds/fq peaking. This YT video might be yours. I am not sure

I hold the belief the Davidlouis VX8 and VX 6 are the 2 FR speakers to beat. 

can someone tell me why Voxativ has their Pi speaker listed at 90 db sens.. when the Driver is 96db sens

I recently got the new Georgia-made Western Electrics for my Eddie Current Studio B amp, and they sound awesome - another category altogether from the JJ's I'd been using. Could I find tubes that were as good or even better than the WE's for less money? Most likely. Am I going to waste any time being concerned about it? Nope. I've spent my money, I've got my tubes, and I am very happy with them! 

I have TJ mesh plates 300B. Very nice tubes. Good value for money. I also have EML 300B Mesh plates that is noticeably better especially in term of refining.

My amplifier has only ~6 Watt output, so mesh plate 300B power rating works.

Does anybody has experience with EML 300B Mesh plate? How are they compared to other 300B?

I’ve WE 300b tubes manufactured Q4 from 1948 and Elrog 300b (2nd generation). The Elrog is as good as the WE, but a different flavor: more air around instruments and less deep sound stage. My preference varies based on the how the album is recorded. The Elrog can be bright for some. I’d spend my $1000 on a sub, MC cartridge, or room treatments. Good luck.
