Reflector 6H23p-EB / 6922 (Premium)
From Wall Of Sound: "The 6H23p-EB tube is refined, restrained and nuanced. Starting with the bass, the 6H23p-EB is slightly less forceful, but more controlled and articulate than the Tesla ECC88/JJ E88CC combination. The midrange is nicely detailed. Male and female vocals are more present and detailed as well. The twang of guitar strings in Knopfler’s Golden Heart is more apparent. This increased detail is not at the expense of treble smoothness : it’s nicely detailed, yet doesn’t seem to overemphasize the vocal sibilance of the McLachlan and McKennitt tracks. There is, on occasion, a very slight treble hardness, but this is a minor failing in light of all the things this tube does well. I have about 90 hours on these tubes and it would not surprise me if this would smooth out a bit more by the 200 hour mark. The price is reasonable for the performance offered, and certainly seems like a bargain compared to the high prices and questionable performance of some of other NOS tubes...I wasn’t expecting the 6H23p-EB to be this good."
This premium Russian built NOS 6922 tube replacement is also known by various Russian names, including 6N23n-EB, 6H23N-EB and 6N23. These are the hard to find NOS (new old stock) of premium quality in both sound and construction.
The 6922 / 6DJ8 tube type is equivalent to the European ECC88 / E88CC tube and can be used in any 6922, 6DJ8 or ECC88 circuit.

A very good tube!
by charlie
This tube has been just fantastic in my Monarchy Dac 24. It is clear without being etched, good midrange, solid bottom end. The Monarchy DAC seems to eat 6922 tubes but not this one. There is some variance in the tube quality some seem to last longer than others but overall this tube is very very good.
Great!
by Soulpatrol
More bass medium and treble very precise and less aggressive.
The best tubes I've bought, tested on my Pathos New Classic One MKII.
Great all-rounder!
by Douglas M. Robertson
The other reviewers were right - this Russian gem is great in both a preamp and a tube DAC. I'm using a Monarchy Audio NM24 and replaced the stock EH 6922's (which is a good, consistent tube for its price) to very pleasant effect. Very revealing in the treble frequencies - cymbals sound very natural - and smoothly linear, probably why it's so good in a DAC's gain stage.
In the line stage they have a smooth, clean presentation with nice imaging and timing, if perhaps a bit lean in the sub 80Hz range. A definite upgrade tube.
Huge improvement in my Grant Fidelity DAC
by Sam Ferraro
This little tube made more of an improvement in my system than any upgrade ever has. Started with speaker cables. Then preamp tube upgrade power amp tube upgrade, interconnect ext. This upgrade to my DAC did more than any of the others did. It tightened the bass dramatically clairity , presence, and soundstage took big leaps too. Never expected that, it was a pleasant surprise. Definitely gonna stock up on these. Best return on investment I've ever had for my system !
Incredible Quality - Long Life
by Tim Rohde
My wife and I bought an Anthem Integrated 2 amp in 2000. These tubes, combined with Sonic Frontier's awesome engineering, produce incredibly deep sound quality. The original tubes are still working perfectly. I thought we'd finally blown one due to lightning nearby. I pulled and inspected both tubes - stunning workmanship. I cleaned everything and reassembled the amp and it is performing flawlessly again.
