Best 6SN7 TUBES out there


hi, looking for best 6SN7 tubes to compliment my Cary Audio SL 80 F1 signature intergrated amp? I have old NOS 6SN7 made in China and have tried Shugaung NATURAL SOUND CV181-T / 6SN7...not overly impressed. Tried 1952 Slyvania bad boys, but tubes were dead. Listen to all kinds of music but prefer clear kids to high vs huge bass slam. Any ideas and places to go other than tube depot or tube store? Looking for reputable on.line store with NOS type tubes, unless you feel there are better new tubes. Thank you.
