    @Zampotech Do you have any experience with non EV version (6N23P)? Any preference for or comments regarding Voskhod or Reflector factory?

    Yes, of course such experience is. The first impression is a large spread of parameters. Without the letter EV the tubes were used in household appliances and they were not paid excessive attention in the manufacture. Therefore, the result depends on luck.
    The second observation is not a very large resource. The 6n24p tube, a close relative of the 6N23P, showed better results in parameter variation and duration of operation.

    6n23p tubes have two variants of electrode structure. The first option-with a closed anode, the second option-with an open anode. I prefer the first option.

    Tubes with the letters E/V/EV were manufactured under the close supervision of representatives of the Ministry of defense. These representatives were directly at the factories. In case of manufacturing of marriage workers of shop ware deduced on a factory yard and were shot from the anti aircraft gun. This is of course a joke. In reality, the workers of the plant suffered heavy losses in wages.

    Kaluga plant "Voshod" and Saratov plant "Reflector" produced decent products and I have no special preferences.
    Not very adequate products produced Novosibirsk plant " NEVZ"

    @rtaylor Have you tried the EH6922 with the Vali 2? I ask because it sounds like the RCA 6CG7 you like has the good things I like about the EH 6922 without the negatives.

    I've switched to an EH 6CG7 in my Vali after using the EH 6922. I find the EH 6CG7 a bit rolled off at top and bottom compared to the 6922 like many have said, but I liked that it was more balanced and less shouty than the 6922 could be at times, and I'm willing to live with the difference. I also think the EH 6CG7 has better control of the bass. It sounds like the RCA 6CG7 might restore the bottom and top I lost while keeping the overall balance.

    I actually have not tried a EH 6922, despite really liking that tube in the MCTH, but that is a different amp.

    The RCA 6CG7 is a much different tube than the EH 6CG7. I tried the EH recently just to make sure I was not hearing things, and confirmed. The top end on the RCA is not hotter per-se, just sweeter. It was an amazing tube in the Vali 2.

    I am still running the GE JAN-5670W though as a daily driver. I just cannot get away from it's openess and realness and it's rich midrange.

    Thanks for the heads up about this tube, @Zampotech. I bought a pair of the Reflektor type from the Saratov factory. They sound lovely in the Vali 2, right up there with the RCA 6CG7 in my opinion. In comparison to the 6CG7, I find the mids to be slightly less wet, tilting the Vali 2 tonality/texture toward a more solid state sound (not in a bad way). They don't have any of the dry raspiness of the stock 6BZ7, and they aren't warm/colored like the GE 5670. Extension at both ends is really good. The thing that stands out is that the 6N23P-EV is quite punchy. The Vali 2/HD600 combo is well established as a synergistic pairing. If it has a fault, it's that it can lack liveliness and be a bit too polite/well-behaved. The 6N23P-EV doesn't change this fundamental character, but it does liven things up somewhat. Percussion feels a bit more visceral and the overall presentation is more exciting. The sonic character seems quite linear and honest, with few sins of commission. I like this tube a lot so far.

    @schiit I was wondering what tube type was used during design of the Vali 2. Was it 6BZ7, or is that just what gets shipped? I've been trying a few different tubes and thought it would be fun to hear one that has the same characteristics - or at least specifications - as the one that was used by Schiit during the design.
    Thank you!

    I have a coaster (Vali Mini) that I've assembled. I like it's sound, it's really listenable. Have any of you guys running Vali2 amps also heard the coaster? What improvements did you hear? I'm hoping that the Vali2 will retain the smooth buttery tone of the Coaster, but with more clarity/detail/instrument separation. It could use a bit more sparkle.

    Oddly enough, I got my coaster back out because of a post on ASR. I visit ASR because a few of the forum members seem to be pretty reasonable and knowledgeable. Not many mind you, but a few.

    Here's the post: https://www.audiosciencereview.com/forum/index.php?threads/the-shoutometer.2555/

    It sort of puts the whole quest for the lowest noise into perspective. If the chart is correct, a signal level of -66db is equivalent to hearing someone shout about mile away. The distance for -72db is 2.55 miles. The fact that the db scale is logarithmic makes the charts you see less intuitive. I know that to represent the differences in levels, it's required, but it doesn't really visually relay how large of a range of levels you are seeing.

    I found myself caught up in the quest for quieter and cleaner amps. Ironic that an ASR post would push me further away from objectivism towards subjectivism. I'm more interested in hearing amps/dacs now than measuring them. If my coaster can sound "good enough" with it's noise levels, then good enough doesn't really mean super quiet. I'd like to further explore tube amps and combinations of amps and headphones. The Vali2 seems like a great place to start.
