Best Tubes on Market today?

I am at the low end of sophistication in this, but my tube needs are limited.  Does anyone have recommendations for the two tubes that go into the PS Audio BHK Pre-Amp and BHK 300 Watt Monoblocks?

Hi

First with respect to buzzing, noise.... My ex wife used to use those plug in air fresheners.   It took me a while to trace, especially after swapping known good tubes and getting the same result.  It was a noise that mimicked a bad tube.   It was on an entirely different circuit, go figure.  

More recently, i had a buzzing in both speakers.  Low level, but irritating.  Turned out to be my Powerline 2000 ethernet over AC adapter I use for my Vault and BluRay...   I switched to a Linksys AC1200 Max wireless bridge.  Amazingly solved all noise issues.  What was strange is my preamp had the buzz in all inputs,  once I removed the ethernet cable, dead silence.

I am using JJ tubes in my Quicksilver Mid Monos and my c-j Classic 2SE and they sound great. I have used Gold Lion and they were great too but the JJ's tone in my system is superb... so good I'm afraid to touch it.

One thing I can say about the Gold Lion is that they are extremely rugged.  Their 6922 is the only tube I've used in that c-j that lasted more than a year before going noisey.  They sound great too.  I've used their 12ax7 and same thing, great tube , long lasting.
