Quietest 6922 type tube?



Just wondering... out of these tube types which tend to be the quietest;

1) Siemens 6922
2) Siemens E88CC
3) Amperex PQ 6922 White Label USA
4) Amperex PO 6922 Orange Label USA
5) Amperex Orange Globe 6DJ8 Holland

I've considered Telefunken but they are much more.

thanks!

FWIW, I contacted a person that I know who used to work for VAC (they used these tubes almost exclusively as stock in their products). This was his answer to my inquiry,

"The Chinese tubes that were labelled Golden Dragon were indeed the "pick of the litter" from the bulk tubes made by Beijing Radio. However, the factory converted to producing light bulbs exclusively about 4-5 years ago, so no more Chinese 9 pin miniature tubes. Assuming that Golden Dragon 6DJ8s continue to be sold, they may be leftover stock or they may be labelled Eastern European or Russian tubes."
Before you buy from Upscale, also checkout the original (from the 70's) Tesla E88CC (6922) and ECC88 (6DJ8). Both sounds exactly like the Telefunken E88CC and ECC88. I have both the telefunken and the Tesla (not JJ Tesla) and I can't tell them apart.
Another quiet and nice sounding tube:
Siemens 7308 A frame. Excellent for phono stage where you need the super low noise the most.

I personally prefer 6DJ8 (7308 is the low noise for 6DJ8) over 6922 family (CCa is the low noise for 69222)

If you prefer more forward sound stage, Amperex D getter 6DJ8 is the best I've ever heard so far. They're pretty quiet too. The "D" getter is from the 50's and early 60's.

Believe me when I say I tried over 20 different type of 6DJ8 tubes.
