2019 300B tubes that are worth the money?

OK, I'm not a super rich audiophile that has unlimited money to blow.  I have a pair of Cary 300 CAD300-SE monoblocks i bought used that currently have a pair of TJ/Full music tubes in them.  I am, overall, very happy with the sound.  So does anyone have a strong opinion that any of the $1000 a pair current production 300b tubes are really worth the money over my $300 pair?  Would my money be better spend on a needle upgrade for my turntable?  :-)

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.

I too urge caution in purchasing Sophia 300b tubes. They failed prematurely, but the warranty was honored. I sold the replacements immediately. BTW, they were no sonic substitute for WE originals from >50 yrs ago by date code. I am trying to minimize the use on the WE. At true AARP-age, the WE may outlive me.

Add me to the list of audiophiles warning of reliability concerns with Sophia 300B tubes. Mine failed <3 months in Sophia’s monoblock amps. Their customer service was disappointing. In sonic comparison to my set of vintage WE 300B tubes (1930’s manufacture), the Sophia’s were good but not great. Original WE are a bit thin in the bass, but the midrange is magical with Voxatix speakers, Rhythmic subs,  and Colibri cartridge. Sophia’s bass was stronger but not enough to recommend them with their reliability issues and unique approach to accountability. My amps are one off monblocks built in So. Korea,
