CHINESE tubes?

In my experience the  Chinese Psvane We 845 are wonderful.

It would be helpful if Ralph _ atmosphere could go into detail about his preferences concerning driver tubes. Psvane versus/ or what ever details that would help end users.

Regarding the boutique tubes: Psvane, Sophia and TJ Music:

This applies only to the 6SN7s so far, but customer feedback on these tubes is that they combine the best qualities of the NOS varieties without their weaknesses! pretty potent comments! No reliability issues have been reported so far (the last 2-3 years or so). Again, these comments apply only to the 6SN7 (there are no boutique 6AS7Gs as yet, and the only other tubes we use are the 12AT7 and 12AU7).

atmosphere:

Thank you for your input. I have only tried the Psvane 6SN7s but I do like what I am hearing. Certainly as good as the NOS tubes I have on hand.

Chinese military nos 6SN7 from DIY HiFi are reliable and very good sounding.

Chinese tubes are quite satisfying in my opinion. Not only more affordable, but also reliable and sonically good. 
I'm using the KT88 from Shuguang and compared to other brands that I tried on the same amplifier, the results (sonically) are not much different - especially when looking at the price difference. 
On other hand, I opted to swap the pre-amplification valves (12AU7 and 12AX7) from Shuguang to Genalex Gold Lion. Not because the Chinese ones were bad, but I truly heard a nice improvement in sound quality for a small amount of money.
