The 6n6p seem very hot on the highs compared to the 6H30. I may try them with the ring dampeners.
Yes , same for me, when I turn off the preamp, I can hear a slight click from the tubes.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.
No Shit ! The designers and manufacturers of their equipment actually know what they are doing … well who would have thought it .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 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've asked a question a while ago if anybody did some tube rolling with Ref6 and did not get any answer, hence i decided to open a new thread so interested might easier find it.
Anyhow, I have a great buddy of mine with BAT gear who several weeks ago did this exact same trick with his gear and was stunned by the change it happened. Namely he swapped 6n30 tubes (apparently super tube) with 6n6p tubes. As within my Ref6 I have the same tubes he advised to try the same. Of course I was reluctant/afraid to do so, so i did a fair share of exploring the web (no info regarding the 6n6p in ARC gear) and also talking with world class tube gear designers and they all confirmed that I can swap them without any issue.
Off to ebay and i got two tightly matched quads and used only 6 pcs for the line stage, as I did not touch the one in the power supply section of the preamp.
Have to say i was quite nervous before turning the preamp ON but as preamp warmed up without glitches moment of truth arise with turning the volume knob from 0 to listening level.
After several notes played I was already sure that something magical happened which left me in total disbelief. Totally different ball game. Music is just flowing, you can literally feel it and touch it, super palpable, notes seem to last longer, dramatically more fluid, you can feel the darkness between the notes and overall feeling is that preamp is much calmer in positive way - like it was super nervous before. Staging as well massively improved. Even my mother, who was at my place, just out of the blue commented wooow this sounds really fantastic now. I had the system on for like an hour to burn in the tubes so will play with it of course further but those babies are not leaving the preamp as to me now 6n6p really are SUPER TUBES.
All in all massive improvement on already great preamp - highly recommended.
PS I did not return the tube rings as i was instructed they are not needed in case of this tubes as they are not microphonic and the cooling is better without them...
Few pics will follow...

In many circuits the 6N6P sounds betterWhy not just use the specified 6N30P?
Hmmm. Interesting!In many circuits the 6N6P sounds better
Soviet/Russian tube so no west block producer did themHmmm. Interesting!
I can't imagine Saša didn't experiment with both tubes in his preamp.
Did Amperex, Mullard or Telefunken ever make an 6N30P?
Eeesh. Thank you.Soviet/Russian tube so no west block producer did them
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.FFS ! Just search 6h30DR , Pre and Post 1990 production .
Good luck finding them.FFS ! Just search 6h30DR , Pre and Post 1990 production .
NOS 6N6P are built a lot like the DRs (such as gold grids) unlike new production 6N30s. My Ayon DAC thanked me personally for switchingFFS ! Just search 6h30DR , Pre and Post 1990 production .
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. I recently went back to the new 6N30s just to see…lasted only a few hours…
Good luck finding them.
