The 6n6p seem very hot on the highs compared to the 6H30. I may try them with the ring dampeners.
Ref6 tube rolling

Do any of you get a slight click from the tubes as they warm up and when you turn the preamp off? Is it anything to be worried about?
i dont know for now , i ordered yesterday six 6N6P for
my REF6SE and i will let you know my feedback after some listening
test.

Yes , same for me, when I turn off the preamp, I can hear a slight click from the tubes.
After one hour of warm-up , my first auditions were very impressive !!
effectively the sound was very good and perhaps better than the 6H30 ,
original vacuum tubes provided by AUDIO RESEARCH in my REF6SE.
The difference is most in the warmth of the sound. It was something like
a 12AX7 or a 6DJ8 .
After 50 hours of listening test or 30 days later, gradually i discovered something in the sound , the warmest in the sound disappeared and
the high frequency became different , no good !!
I decided to change all 6H6P in the audio section to all original 6H30.
SURPRISE !! OH MY GOD !
THE 6H30 ARE FANTASTIC !! Good high frequency , good image , better midrange .
I think that these 6H6P GOLD grid were most designed to drive speakers
than a preamp output in AUDIO RESEARCH.
Thanks for reading my feedback about these tubes.
No Shit ! The designers and manufacturers of their equipment actually know what they are doing … well who would have thought it .
I did this swap in all my products that use 6N30P tubes. The Ayon Crossfire III benefited as did the Ayon Skylla 2 DAC. What you can't do is replace a 6N6p based product with a 6N30P...it has to do with the current draw of the heater being higher for the 6N30P.
I have a big stock of 6N6P, I tested many boxes of bulk or NIB 100 pieces the powerful ones and best matched I sell as replacement for 6N30P. Tested on Roetest wich deliver current, gm, gain and curves for each tube, I analyze them and select matched. Usually I select matched quads but at request I selected and sold matched sextet. Many buyers were surprised by the sound of 6N6P and bought again, recently I sent 10 matched quads to Poland. Now available from 2 100 tubes boxes, one from 1979 and one 1983, both red tip, they are listed on ebay, also send PM here and we can arrange, shipping $15 worldwide, shipping time 10 days.
I see that some have tried the 6N6P's in either the REF 10 line or phono stage selectively, ie. just the gain stage, just the cathode follower or just the power supply to see how the sound changes. With changes made to my ARC stuff, I like the 6H30s a lot except on fairly rare occasions the highs can be a little hard sounding so I'll try different combinations. I also don't want to give up any gain.
Also, how often are you finding you need to change the 6N6P tubes given that they're usually run at a lower filament current?

Hmmm. Interesting!
I can't imagine Saša didn't experiment with both tubes in his preamp.
Did Amperex, Mullard or Telefunken ever make an 6N30P?
They were the best I got some of 70´s. Best matching, and they can be used 10000 hours. Now , you cannot find them anymore, at price was already so high 10 years ago.
NOS 6N6P are built a lot like the DRs (such as gold grids) unlike new production 6N30s. My Ayon DAC thanked me personally for switching

Yup … factory production standards were seemingly declining even as early as the later 90’s
