Electro-Harmonix 6922 EH Vacuum Tube

Wow! I figured rolling the tube in my Schiit stack from the stock tube to this tube would improve the sound at the margins, but it’s like a layer of gauze was cleaned off the tweeters! I laugh usually when I hear “dimension and spread” and other non-technical terms thrown by the audiophile community but I gotta say, this is not tiptoeing in the margins this is a fastball down the middle! I feel stupid having waited 6 months to make this big of an improvement to my DAWs playback chain.

So far after testing the stock Canadian tube, an old soviet tube, JJ tube and this, this is my favorite tube so far, by a lot. It is very detailed and sharp in comparison to the other 2 tubes I have tried. The bass is very nice in this, bass seems bloated and slow in the other 2 tubes. The JJ tubes sound very similar to a solid state to me, it is nothing special, but nothing terrible.

I recently bought a Schiit Vali 2 headphone amp, along with a Schiit Modi DAC, Drop + Sennheiser HD6xx headphones, and Drop + HiFiMan HE5xx headphones. Compared to both the Schiit stock tube and the Electro-Harmonix 6CG7 tube, I found this Electro-Harmonix 6922 to be the best. To my ears it has the richest, warmest, and smoothest sound of the three. I also found it to have the widest soundstage. I know everyone has their own personal preferences when it comes to tubes and headphones, but this 6922 tube was definitely my favorite of the ones I've paired with my Schiit Vali 2.

Oh my God, I thought it may be too little of an upgrade to discernible. Boy was I wrong. I just replaced the stock tube in my Schit Vali 2 with this baby and I am listening to music that is alive and the tube isn't even burned in yet. I highly recommend this tube, the sound is rich, clear and wonderful.

Very nice tube. Accurate, clean sound throughout the frequency range. An upgrade over the stock tube included with the Vali 2+ (which aren’t bad tubes, but sound dull in comparison to the EH). To my ears these lack the holographic soundstage imaging which you find in the next (invariably more expensive) tier of 6922 tubes. Good service from Tonal Tubes.
