    Any comment/hypothesis as to *why* there's an overshoot?

    Is it the inherently balanced topology is simply cleaner? Or perhaps the current draw due to shorting the negative leg causes issues for the positive?

    ^ This.

    More effortless (more power), better articulation across the spectrum, more precision imaging, separation, and layering, more impact, more plankton.

    For the guy who asked about O2: more power is always better.

    I had the whole writeup written, but after re-reading it, I realized I went too Head-Fi on it with per track impressions. I'll cut everything short and just say that I listened to Alicia Keys Unplugged.

    First of all, the the O2 doesn't sound bad. It's pretty good sounding until you compare to something better. My O2 uses the LM4562 for voltage gain, so it's warmer sounding and less strident than stock O2s. In terms of tonal signature, the O2 is warmer sounding with a tiny tiny bit of stridency.

    In terms of technicalities, my overall assessment is that the O2 sounds like farty poops. The bass is thuddy. Kick drums sound like farts. The Jotun has crisper faster transients, resulting in a more tactile less compressed feel. The O2 sort of blurs and blends everything together like poop in a diaper. Delicate sounds like cymbal brushes sound muted, their delays obscured from existence. Even simple piano work with a few sustained notes gets congested on the O2. Yup, take that poop and smear it all over the window. It's like looking through a window, a lightly frosted screen that converts real world 3D images into 2D renderings, smeared with poop from the poopy diaper.

    There is no scientific explanation why the O2 sounds like smeared baby poop on lightly frosted screen that displays 2D images, but it does.

    Anyone know how the Joutheim (Balanced) compares to a Bifrost MB/Valhalla 2 Combo?
    Is this unit better than a Bifrost MB/Valhalla 2 combo?

    I say this with the utmost respect, admiration, perhaps even love ...

    But you wonderful pack of bastards are not making it any easier to resist buying a Jotunheim just to see what all the fuss is about!

    Between the HD800S and Utopia, the resolution limits of the little Vali 2, delightful though it is, are quite apparent in my bedside rig. And now you have me wanting to replace that with a Jotunheim, feed it with the MOMBY that's already there, include the Phono module, and actually put a basic turntable by my bedside.

    Or maybe move the current turntable there and use that as a "justification" to undertake a major upgrade in my main rig ...

    Plugging Jotunheim into the Jensen step-ups on my vinyl rig. Will report back in an hour.

    I like the amp better than the Valhalla 2 for HD6xx and my IEMs. The Bifrost MB is clearly head and shoulders better than the built in DAC on the Jotunheim.. With your modded HD800s, I'd probably stick with the Valhalla 2, though.


    No, sell HD800s, sell Vali 2, save, buy ZDS first. Then worry about this thing. You have endgame transducers, treat em right first. f**k this thread until you do.

    So the Jot is like a nice compact perfectly formed piece of shit in a pristine white toilet with crystal gleaming glass in a sunlit bathroom (with songbirds tweeting outside and a perfectly groomed dog lying in the hallway)?

    :) sorry, I couldn't resist

    Jotunheim: A very precise German toilet that leaves everything as is over the water line and shows you everything you wanted to know or not know about your shit.

    Jotunheim Phonostage Assessment

    I compared four phonostages, including the built-in Jotunheim phonostage. I am running a Cadenza Bronze MC cart into SUTs. The SUTs are expensive Jensens that go for about $250 a pop. If I bought them from Jensen, I could probably put them in nice boxes, call them Marv's Devices, and sell them for $1200. I ran all of the phonostages via the SUTs to keep things consistent (apples to apples), even though some of the phonostages can work with MC carts.

    First of all, I am happy to report that the upper mid forwardness or aggressiveness of the Jotunheim is 100% gone from the vinyl setup. Keep in mind that I don't have a forgiving TT setup either. It's a neutral table with a very slightly full bodied cart. Digital is just weird sometimes.

    I quickly compared the following four phonostages:

    1. Built-in Jotunheim
    2. Schiit Mani
    3. RSA Nighthawk
    4. EC SS prototype (will never be released)
    The EC is the one that I currently use with the SUTs. It's the best one with the best synergy with the SUTs. The RSA, being MC capable, performs best without the SUT, but is still behind the EC/SUT combination. I had already established these two things beforehand, but did another quick comparison to verify.

    Surprisingly, the built-in phonostage of the Jotunheim is a little bit behind the RSA in third place, but not by much. If anything, it's just slightly more veiled. Last place is Mani, which is even more veiled and lacks the liveliness of the three other phonostages. Yup, the built-in Jotunheim phonostage is better than Mani, and closer to the two phonostages that I am currently running on a day-to-day basis than to Mani.

    Totally appreciate where you're coming from!

    It's probably not clear where I'm coming from though (and no reason it should be).

    My bed-side rig is just that; something I have by the side of the bed for the, relatively rare, occasions where I am listening to music before retiring with my darling fiancé (if she's around when I retire, which she usually is, it's an entirely different kind of "music" that I'l be focusing on). Right now that rig is a MOMBY/Vali 2, for no particular reason other than I wanted to see how it performed. Prior to that it was a MHDT Stockholm V2/Woo WA6 ... which I retired due to, well, killing more than one set of tubes as various things (mostly of the Agent Provocateur persuasion) got energetically propelled about the room (and it being a bit "big" for just sitting on the nightstand).

    I'm just thinking about a Jotunheim in that rig as a better way to drive whatever set of cans (Utopia, Abyss, LCD-4, HD800S primarily) I happen to carry up the stairs with me that evening, whilst (yes, I'm English) wanting to keep that configuration as clean and compact and simple as possible. And, of course, to satisfy my curiosity as it relates to all the enthusiasm around the thing.

    A ZDS in my main rig, or my secondary or tertiary setups (multiple homes, multiple listening rooms in each) is definitely intriguing. I struggle a bit with aesthetics there ... a problematic issue for me as an audiophile and music lover, but I remain interested. I am in the unprecedentedly fortunate position of not needing to save or sell to go in that direction, but it's not really a solution for my bed-side setup. Strictly speaking, neither is a turntable, even if only for reasons of dust, but I digress.

    If I was less lucky in life, then the save/sell advice would be spot on.

    As it is, my primary source is an Yggdrasil (and I'm in the process of seeing what else really challenges that). And then it's feeding a Ragnarok and WA5-LE Mk2 (w/ all upgrades and both TAK 300B and 274B tubes). Open to other options, always, but mostly looking to reduce my "box count" and get better results in specific, limited scenarios, than anything else.

    Also ... while it's tempting to buy a Jotunheim "just because"; I'm trying to be conscientious about not accumulating more "stuff" while in the process of moving and wanting to consolidate gear (not just audio) to stuff that actually gets used ...

    @Marvey You're really not helping! ;)

    Okay, you ARE ... but I want less gear right now, not more!

    And now you not only have me wanting to piddle about with a Jotunheim, but wanting to see how the Nighthawk compares to the phono-stage and ADC/software RIAA EQ in my Linn Akurate DSM/1 ...

    Coming from someone who appears to have a considerable budget for gear, this is really sensible advice.

    I'd like to second this. Plenty of comments out there on the synergy with HD650 (which there is), but I'm pleasantly surprised by how great the TH-X00 PH sound with the Jodie. It really smooths out the treble without losing any detail.

    The great news is that Massdrop just listed a pre-built O2 amp again. Quick everybody!

    Is it fair to infer from the above that you feel the mid-forwardness of the Jotun does not mesh well with HD650M, hence the return to stock (soon to be stock-plus-dampener)? Interested in any updates or comparisons on the Jotun between the two headphones now that your stock pair arrived.

    Jotun goes just fine with a modded HD650.
