The NOS 6H23P-EB (Premium) preamp tube is a very noticeable upgrade over the Sovtek 6922 vacuum tube and Electro Harmonix 6922 preamp tube. They are incredibly durable and can handle the punishment of modern pre-amps, including those made by Audible Illusions. They excel in detail, speed, and soundstage. The highs have air and sound natural.

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.

Reflector 6H23P-EB / 6922 | Headphone amp upgrade

by -

Yeah, Baby! These 6H23P-EB are very sweet sounding. I replaced the JAN Phillips 6922's in my Musical Fidelity X-CAN V3 headphone amp with these, at the recommendation of Rock Grotto in the UK. The 6922's were pretty old, but the difference was huge! More space, air and clarity, great bottom as well.
Huge thanks to Jon for pointing out that the 12AX7's I ordered were the wrong tubes, and agreeing with the Rock Grotto suggestion.
I'm a happy camper!

Reflector 6H23P-EB / 6922 | I like 'em!

by -

After blowing a few BugleBoys, these 6H23P-EB were recommended for my new-to-me Anthem Pre1L which evidently eats some tubes. Nothing like hearing a bang when you turn it on. I'm no audiophile but I like what I hear.

Reflector 6H23P-EB / 6922 | Great upgrade for the Schiit Vali 2+


I concur with the review by the Wall of Sound, except I don't hear any treble hardness. Great upgrade to the stock 6BQ7A J22 Channel Master, Japan tube that was supplied with my Schiit Vali 2+! Listening with Drop + Dan Clark Audio Aeon Open X Headphones. Greater definition, wider sounstage, and greater bass resolution than the stock tube. Thoroughly recommended 6922 upgrade for the Vali 2+.

Reflector 6H23P-EB / 6922 | Pair matched 6H23P-EB- VERY nice, no complaints


Have about 20 hours on these 6H23P-EB. VERY happy with them. Very musical, clear, clean, great highs, mid-range and lows. Quiet. Lots of 'air' around the instruments. My amp is a Decware Torii Jr. I need to roll my 12AX7 tubes in my pre-amp to see which one works best with these new tubes. Very happy that I sprang for these. I mostly listen to Getz, Oscar, Miles, Steely Dan, Dire Straits, Bill Evans, Jimi, Eric - so jazz, rock, blues.

Reflector 6H23P-EB / 6922 | Good sound stage


Installed the 6H23P-EB in a Xindak 6200 i change the Electro-Hamonix because there is a hum on the left. Now the sound stage is more larger and deeper, bass is more deep and controlled, medium and high are detailed. There is a black effect, very cool when I listen to classic.
