Replacement recommendations for Shuguang 6N8P-J tubes

[grafxdesin]

I have a Consonance Cyber-222 and it time for new tubes. They have the Shuguang 6N8P-J tubes that came with it and it still sounds good but it's time for an upgrade. I am looking for some recommendations, two I am currently looking are:
6SN7GTB Coin Base
Tung-Sol 6SN7GTB
What about Balanced Triodes, High Gain, Low Noise & Microphonics, Matching? (Through tubedepot.com)
What websites are good for ordering these tubes?
I could also replace the 5AR4 rectifier tube (Sovtek) as well, should I?
Cheers
Adam

Basically just looking for a good 6SN7 tube in the $20-$40 range, I will need 4 of them.

Replacing tubes should never be taken lightly (unless they are cheap chinese junk, and even lousy Russian tubes are a couple orders of magnitude better.). Rectifiers, especially the 5ar4/gz34 are getting harder to find in OLD STOCK (Mullards are the De-Rigure 5ar4) However the new Russian Rectifiers are getting better. And they are fairly cheap comparatively.
6sn7GTB's are good tubes and EVERYONE wants old stock. And the prices are rising accordingly. There are some decent Russian Re-Issues from EH and Tung-Sol(both made in the old Reflektor Plant).


Drop over to Jim McShane's site. http://www.mcshanedesign.net/tubes.htm He tests tubes with a custom rig at operating voltages and can match triodes, etc. and his costs are in line with the commercial sites that just test on a high end tube tester.
