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?

 EXACTLY!
ei001h- Far as, "best tubes on market"; the best are all NOS, from reputable dealers(as mentioned above). Since you asked about, "best’ for you; that depends on your taste in reproduction. It’s been my experience, that many like a warm, sweet, what some call, "tubey" sound. If that appeals to you, stick with British(ie: Mullard or Brimar) If a cleaner, more detailed presentation attracts you; go with German tubes(ie:Teles or Siemens). Somewhere in the middle, are Amperex/Bugle Boy, Pope and Phillips(Holland). NOS American tubes can go either way. The previous comments are focused on nine-pin Miniatures. I’ll include a list/comparison survey, which deals with the 6SN7 family. I’ve found the first author’s comments/impressions quite accurate (all my personal favorites are bottom-gettered) . With the prices that NOS output tubes are now commanding; current production is very attractive. No experience here, regarding SET output valves. http://www.dehavillandhifi.com/6sn7_vt.htm and: https://www.head-fi.org/threads/the-reference-6sn7-thread.117677/
