    I think this is what you're looking for:

    https://www.head-fi.org/threads/hap...ng-modi-multibit.815368/page-59#post-12827522

    where Mike Moffat says it’s the DAC chip settling into its integral nonlinearity spec rather than just being thermally stable.

    Are these impressions while using stock tubes, tung sol, or the SS Tube?

    No SS. Stock TS, vintage TS BGRP, Sylvania chrome dome. The Lyr 3's tonal character changes a bit, but not a whole lot. Note that I haven't tried the 6SN7s on the more extreme bassier or bright ends, nor the exotic ones I have stashes. And 6SN7s tend to sound more similar than not.

    Settling time is 2^n where n = number of bits.

    Gungnir Multibit takes 6-8 hours to sound good and 2 days for optimal sound. Yggdrasil (two more bits than Gungnir Multibit) takes one day to sound decent and 8 days for optimal sound.

    Modi Multibit or the MB card, being two less bits, should theoretically only require 1.5-2 hours for it to sound decent.

    Note that use over time seems to reduce the time needed for equilibrium. The Theta Gen V I had only required a few minutes. A broken in Gungnir Multibit only required 18-24 hours for optimal sound. So a well used Lyr 3 with MB module might only need 30 minutes. Just turn the thing on a half hour before use - the tube needs to warm up too.

    Kinda shitposting b/c brevity, but just got Lyr3 - Gungnir Multibit to Freya (passive) to Ly3, RCA red base 5692, HD650K, and this thing sounds goooood. Zero treble etch, midbass punch is really involving. Good bass extension; not quite as bloomy in the lower bass as Cavalli LC. Much better space and separation than Cavalli LC, even despite LC balanced vs. Lyr3 SE. Lyr3 is cleeean. Songs where I thought there was a tiny bit of treble hash/distortion in the recording are now resolving to the limits of the chain. At least, I think...

    Edit: Andro pairs well, super smooth up top, and a bit more mid-centric. Bass (sub 100hz) is just a touch more emphasized compared to Magni2U. Only an eentsy-weeentsy-teeny-tiny but of hum. And Lyr3 seems to be grabbing TH-X00EB by the balls. Bass is still pronounced, but better control, especially in the 40-80hz range. On Pantha du Prince, Elements of Light, "Particle" - the initial bass hit @2:45 is more like a sealed 15" sub than a floppy ported 12".

    EditEdit: holy shit! thanks for the friend status!

    EditEditEdit: Just FYI in case it hasn't been mentioned, the Lyr3 case will accept big-glass 6SN7 valves, e.g., Psvane, TJ Full Music, Sophia, etc., without needing a socket-saver, unlike Freya.

    OK, just caved in, ordered my first (semi-)tube headamp, after an increasingly pricey sequence of solid-state headamps. The urge to hear what it sounds like got the better of me. With TS tube, no module. It will be competing against a Neurochrome HP-1. (Lame excuse dept: sold no-longer-used mountaineering gear for more than the new amp :D)

    Has the original dac card for the Jot been updated? It was universally written off as shite compared to the Modi Multibit but when I had the chance to compare the two I felt the Modi Multibit’s prowess was overstated.

    Yes. The original DAC card has been replaced by the AKM4490 card.

    The original DAC card is also a AKM4490 card, the new one is just a G2.

    It's no different from NOS tubes, the tech hasn't changed since the '30s.

    Definitely get balanced triodes at least. I usually get low microphonics too.

    I don't get high gain unless it's a noticeably low gain amp like the Aficionado.

    And if you order one of these tubes from Schiit, are they doing any of this stuff?

    Sorry, I smell rip-off, so I'm being thorough.

    Schiit has always been good about avoiding false claims. Their amps support tube-rolling, but don't make claims that you'll hear any difference. Some of us swap tubes and hear diffs, some may not.

    Probably only balanced triodes. If they didn't you'd have channel imbalance built into the circuit via the tube.

    I haven't heard anything about it magically balancing tubes that have different gains per triode, but anything is possible? Shoot Schiit an email.

    It's a hybrid amp, so you should not expect to hear the same magnitude of differences (when rolling tubes) vs a pure tube amp.

    Personally I hear significant differences swapping tubes in my MJ2, and such a dramatic difference swapping the LISST, but also... if this is one's first hybrid, I'd vote just go with stock, modern, recommended tubes to start. See how it works for you. Tube rolling, rare tubes, etc. can come later.

    Maybe balanced triodes, but what does this mean? Does this actually mean gain is the same or does it mean that current draw is the same (which won't matter as long as it's not totally off).

    P.S. I should probably start a service where I buy a bunch of tubes and measure gain and distortion to match the two triodes to sell. This would be real balanced triodes / tube matching.

    Long time lurker, first time post.

    Having lived with the Asgard2 for several years now and being quite satisfied, I'm looking to shake it up a bit. Is the Lyr3 going to be step in a good direction would you say? Got the LCD3F.

    I cannot recommend this enough... if you are one of those people who get hooked on the sound of tubes, you'll never go back to another pure SS amp again. That organic, analog, holographic, tube sound is addicting. +1 vote you give this new amp a try.

    @purr1n How hot does your Lyr run?

    I'm trying to figure out why @Elnrik 's amp will fry eggs and mine barely gets warm at all.
