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 also recommend Andy from vintage tube Services Inc.. I've been buying from him for years never had a problem with tubes.
As someone else suggested I would get rid of the noise in the amplifier before changing tubes.
I only have experience with Siemens 12Au7s bought from upscale audio. I use them in my phono preamplifier and also in my Zesto bia120 amplifier.  They are similar sounding to Telefunkens. They tend to give you more detail than other tubes in the same class.
