The Genalex Gold Lion PX300B ($218/pair on vivatubes.com) made a nice upgrade from the Shuguang tubes (basic version) that came with my Elekit TU-8600, and they are generally highly rated for their price/performance.
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? :-)
