    I feel like there are subreddits for at least three of these...

    @schiit - Dude...

    Measurements are a means of explaining what we hear. We don't listen to measurements. Beethoven's Sine wave in 1kHz Major doesn't fucking exist. Thing is, twatwaffles like Amir don't get that. Hell, he's got it completely backwards. I sincerely doubt he could tell the difference between a S19 and a Yggdrasil, because he doesn't listen to anything! That dipshit doesn't have the ears for it.

    I'll trust my ears, and my ears tell me I like Schiit. I prefer your MB DACs over the other DACs I've heard. Love it. A lot. ...not as much as my dog, even though my Gungnir Multibit never pissed on the carpet or got on the counter and stole slices of pizza... but still.

    So, keep on keeping on.

    And Fuck Amir (and insomnia) in his hairy goat ass.

    Multibit is here to stay. If someone manages to make SD sound as good as multibit,
    it will be more expensive due to paralleled chips and ridiculously expensive clocks.

    Super low thd for the exchange of plasticky timber (steely, or downright nasty are also popular options),
    weird dynamics structure, lack of stage projection, lack of plankton or in some cases just incredible dullness?
    AMIR and his kind can roll up the thd&linearity envy and stick it where it belongs.

    For god knows what reason people can now get some good sounding headphone rig for less than a 1k$ total.
    People should be reminded that some 8 y ago with budget of one grand one could only cry about it or diy.
    I wonder if the personal hi-fi world changed by itself or Schiit had something to do with it?

    Yes, a shady Huawei phone with a dongle for everyone!

    Seriously though- you listen to your stuff, you have the sales figures. We're all pretty confident that you're a pragmatic and level-headed person. No doubt you and Mike would have got the fuck out if it didn't make sonic or financial sense.

    Maybe this is just a sign of success- you have your own corporate stalkers now- you've arrived.

    (..and yeah, you fuck up sometimes- if you didn't, it'd be suspicious. You tend to make good on it though, and that's the important thing.)

    I bought a 9 month old Jotunheim (amp only) from a member here a few weeks ago. The first time I listened to it I very quickly PM'd the seller to ask if he had used the amp before he sent it to me. My first account of this amp was the fact that it was incredibly noisy. I was feeding it with single-ended RCA outputs from a new Audio-GD NFB11.38. They were both plugged into the same Furman PST-8 power strip using Wireworld Electra 7 power cables. Nothing else was plugged into this strip, but of course it was on a shared circuit in the same room with PC equipment. Headphones are Focal Clear with single ended and balanced cable.

    I tried the same setup using an Auralic Taurus MKII. Much, much quieter than the Jot. I can only say that subjectively the difference in noise was extremely obvious. The Taurus was substantially quieter than the Jot, but there was still some noise present when the volume was cranked. The Jot had audible noise even at low volumes, and the noise was almost unbearable with the volume knob at max.

    Fast forward to last week when I brought my Holo Spring DAC into the office and used balanced XLR into the Jot. SILENCE. All of the noise that I experienced before is completely indiscernible to my ears, even with the volume of the Jot at max.

    Is this normal? Is there a grounding issue with this Jot? Should we just not use single-ended inputs on the Jot? Should they be eliminated altogether? I've had numerous amps that are not anywhere near this noisy using RCA inputs.

    This could be a noisy source, bad cables, a ground loop, or there may be an issue with the Jotunheim. After you’ve gone through the Troubleshooting part of our website, if you’re still having issues, contact us at [email protected] and we’ll have a look.

    That place is just as douchey as I remember. I'm going to wipe my cache and clean my monitor.

    Or it could be just XLR interconnects vs SE cables. I did experience that with no Schiit components. Emotiva DC-1 SE to a single NuForce HA-200, SE cable, was noisy like hell, I have two HA-200 and tried with both. The same DC-1, balanced cables to two HA-200 setup as mono blocks and was very quiet. EMI, power, whatever it was I think XLR interconnects are just better.

    I know people who work there, this statement rings pretty true. Although hard not to with an office off Austin's infamous 6th street.

    As a rando/noob/googan to this site I have to ask why no one is calling a spade a spade: seems pretty obvious that the denizens of Amiristan have an agenda which is motivated by payola. Having dealt with China contract manufacturing for almost 30 years this isn't the first example I've seen of it, both online and thru various trade organization meetings and publications. I never cease to be amazed by how much information about my company's order volume is shared between the supposedly competing vendors i deal with on the mainland.
    So what do you do when an outsider starts making serious inroads on your sales volume? Better quality,lower pricing, better service?
    Nah, costs to much vs assasination.
    Conspiracy theory? Sure,tell me what you think after dealing with the Dragon for a couple of decades.

    From that description, most likely your SE cables are picking up electrical noise from the environment. I also own a Spring DAC. XLR into Jot, dead quiet. SE into Lyr 3, hum until I used a shielded power cable with the Lyr 3 and raised the (good) SE cables well above the power cable. SE (RCA) cable routing really matters.

    I came across this forum and thread today when I was trying to find out who AmirM is. (recently realized he was the creator but later banned from whatsbestforum)
    Last year I had a friend of mine who innocently submitted a Klyne headamp to one of his "free testing events"
    Despite express protest by the owner and Stan Klyne Amir posted his set of spectacularly bad results on his forum.
    Same deal, 60Hz noise that would have made a phono stage unbearable.
    I dont know Stan Klyne in person but I sure know his products. Used them in the 80s and have to say they are still the quietest out there.
    I am not a vendor and I dont profess deep knowledge. But I do know how to fix a lot of gear, build quiet line stages, and most importantly question the validity of a test when certain measurements are outstandingly bad and should be audible to the ear. Just couldnt keep my mouth shut and recently voiced my opinion related to this incident on 2 FB pages called "SF bay Area Audiophiles" and a more appropriately named page "Audio Bullshit" and that's how I realize the very aggressive fan base this Amir character has lurking behind the scenes.
    I think high-end audio is badly polluted with snake oil merchants pushing incredible tweaks, at least one of them is humorous about it (I think most know who I am referring to). But I think pseudo-science is WAY more toxic in comparison.

    Recently flipped through a few pages on that forum and wish I could have those 15 min of my life back. Sheer idiocy.
