    My take when I was trying out tubes in the MJ2: the WE396s are warm and bloomy in the bass, a bit rolled up top, a bit slow, not the clearest, but with great macro and microdynamics, plenty of colour/wetness in the mids and a somewhat deep soundstage. They aren't the be all and end all but they are good. Personally I dislike prominent bass (particularly since the MJ2 tends that way anyway) and so preferred Siemens E88CC which are not stupidly expensive on ebay, but are faster and clearer, and more neutral in the bass while still retaining some tubey wetness in the mids (tastefully done, not to excess). Headstage not as good though.

    YMMV of course. There are plenty of good, detailed impressions earlier in the thread depending on what you are after. 6922 family prices are not very sane unfortunately.

    How much better are the macro/microdynamics (particularly micro) over the Siemens E88CC? I really enjoy my pair of A-frames, but the amount of flowery prose written about the WE396a always has me curious if it's worth the splurge.

    This was a while ago now but I think microdynamics are similar. For macrodynamics - I always found the MJ2 a bit aggressive and compressed which seemed to level different tubes out a lot in this regard. The main difference is in the soundstage (deeper and less up front) and the bass (slower and a bit bloomy).

    I had purchased this amp as my first "real" amp and let me tell you... I do miss it since I've sold it. The only reason I haven't purchased another one is that I am secretly hoping they will release a MJ3.

    Dropped into the Schiitr this past Saturday to fiddle and listen to some gear. Walked out with a Mjolnir 2. https://imgur.com/a/hu4L6Zn

    It took a few days to burn in, but the sound cleared up and the lower end came in.
    I can here more detail in my JBL 305s/310s.
    Look forward to start rolling.

    I suggest looking into 5670/396A tubes. There are some reasonable priced GE tubes available. You just need an adapter.

    I have WE396a's and adapters down here in Glendale if you want to try those. The Mjolnir 2 isn't known for being all that affected by changing tubes and I wouldn't go to crazy spending cash on rolling. I have a warmed up Gungnir Multibit also if you wanted to try that pairing, unless you already have.

    I might take you up on the WE396's, also have a Gungnir Multibit on the way.

    How long do I need to leave that on to burn in/warm up? Thanks

    I’m sure you’ll want to hear the new Gungnir Multibit ASAP, so I’d say you can start playing and listening maybe 3-4 hours. I’ve found on my Gungnir Multibit you can get close to 90-95% with just that. 8-12 hours gets you really really close.

    And like @BillOhio said just leave it on forever.

    Got both the Gungnir Multibit and Mjolnir 2 up and running. Ran them for 3 days strait on stock tubes. They sound great with headphones, and made my JBL 305's brighter with more detail. I did buy the LISST tubes... do they need burn in time also?

    Curious to know if anyone here had tried connecting the Mjolnir 2 to a speaker amp. Ive seen some folks use the Mjolnir 2 with their active speakers.
