Best Tubes on Market today?

I'd like to upgrade tubes on my Mastersound Compact 845 SET.
I'm getting a loud buzzing noise from both channels at  listening position which I find extremely annoying.
 My current tubes are Shuguang 845C (cheap Chinese electron). Pre amp tubes are Tungsram ECC82 and driver tubes 6SN7 EH. Probably all cheap stock tubes. I Love the the sweet sound but noise level is unacceptable.  Also very audible transformer noise, but I doubt there is a fix for that. Are there other ways to minimize tube/transformer noise?

What are the most reliable aforementioned tubes out there and what is the best place to get them?
Upscale audio seems to have quite a selection. PSVANE was also recommended by some. 
 I would prefer not to spend more than $600 on 845 tubes and hoping for reliable clean sounding tubes all around.    
I also have C2600 preamp with stock tubes. Any advice on those?

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.
