1975 New Reflektor 6n23p SWGP or Siemens/Amperex/Telefunken Cca?


Contemplating shooting for the moon with the 6DJ8/6922 tube type.  The moon appears to be either the 1975 New Reflektor 6n23p SWGP or Siemens/Amperex/Telefunken Cca.  For reference, the link below asserts the former is the Holy Grail.

Curious what the here assembled opine.

Would be installed into a 2006 Dodd Battery Powered Preamp that is currently populated with early 1960s Siemens large halo getter e188cc (7308), which are great.  Objective of the moonshot would be more of the same that the current tubes are delivering...if such is possible.  Or, as any card carrying audiophile would espouse, something even better.

Thanks in advance for opinions, particularly from any audionaughts who have taken this particular journey.

Hi grey9hound. Yes, I’m sure that the Siemens are well broken in. Here’s what I wrote earlier in this thread: "...the matched Siemens e188cc were bought from Upscale Audio in 1997 and used for only a few months in a Sonic Frontiers SFS-80 amp before selling the amp and stashing the tubes...". Probably 300-500 hours of use in 1997...but probably another 400-600 hours in 2020-2021 in our Dodd Battery Powered preamp. So, yes, by any normal accounting, they’re well broken in.

Just something very special about the Voskhods.

With all the Voskhod 6N23Ps around, priced anywhere from $8.00 on up, how do you choose which to buy (not looking for HG versions)  ??

Does it make a difference if they will be going into a phono stage vs say an amp or preamp ?

Just want to try a pair for the fun of it.

@scm i bought set of 5 on ebay $35 and made sure they were Voskhod Rocket’s.  I bought from a source in Ukraine thinking if it doesn’t work out it will be a donation to help someone out in their horrible war situation.  I picked one listed as new, tested, VRocket’s set of 5 hoping I could get 2 good ones.  No problems they arrived in about 3 weeks well packed.  They were a mix of dates ‘76, ‘81, ‘83 and did not look new but not bad.  Some labels worn down.  Pins looked good. I tested the tubes and got one closely matched balanced pair 95% GM.  The other 3 were all good but not as balanced and GM in 70’s - 90’s with one being very unbalanced.  Overall a success in my mind.  If I do it again I would look for listed date codes from ‘74-‘79 listed as tested hopefully with results.  But its a crap shoot.  Think of it as helping out Ukrainians.  Good luck!
