    Or use the SE. People talk as if the SE output on the Yggdrasil/Gungnir Multibit is gimped or something. It's not. I run the SE into the ZD, BA, Studio or whatever amp I happen to have at home for the moment. It takes a very very high quality ($$$) line-level transformer to sound better than the SE out; and even then, a transformer, no matter how good, will add distortion and phase shift at the extremes.

    FWIW, we are exploring the idea of a tube buffer for Yggdrasil/Gungnir Multibit. The problem is that there are many different approaches, some more expensive than others.

    What I think is enchanting, aesthetically speaking, is, since my Studio PSU occupies a prominent position right next to the amp on the top shelf of my audio rack, the hardware bolt hex head on its face plate adds just enough silver accent to the solid black face to be downright eye catchingly alluring. But since it's prolly just nickel plated, is a stainless steel bolt upgrade in the works? ;)

    Luv that 'Ultra Heathkit' retro look.

    BTW, I personally run SE on most of my interconnects, anyway, so after I establish a baseline signature with the M7 DAC, I'll switch over to the Yggdrasil for comparison. Or not.

    Do we know if the Studio is going to play well with other popular DACs via balanced? How much is the problem limited to just Yggdrasil and Gun-MB?

    I tried Studio with 3 other DAC's balanced - worked like a champ.

    You know I'm curious about this. I'd love to talk details, even if it's a one-off.

    The HD800 sings in my setup.

    Hi folks, how good is the EC Studio as a preamp?

    According to craig, these are not suitable as a preamp.

    The zd would be the best ec amp to use as a preamp

    Does anyone know what is the availability of the Studio Amp going forward ?

    Just curious, but why is it that some yggdrasils have this issue, and others don't? Is it a matter of cherry picking- or that actually all have the issue, just that some have it more obvious than others?

    As a recording that's recorded at lower levels will not require as much current, it's possible that ones library might not exhibit the distortion. Add to that the tolerances of the 'picked parts'- might be enough to keep it from distorting. I'm traveling now for work, but when home I'll make a sample available that is hot; see if others get distortion.

    I find that my Studio plays best with my speakers. Most of my headphones appear voiced for SS amp synergy, i.e. warm and dark, sometimes almost veiled, in Studio pairing evaluations. The HP800 are the only ones I own that seemed voiced for tube amps per se, i.e. still open and clear with the pairing. The Studio appears to be rather picky with HP pairings.

    What other headphones do you have?

    I thought people were saying EC Studio is towards bright sounding.. which supposedly did not play very nice with the HD800s. Are your HD800s modded?

    No, my HD800 is still stock. The other headphones I own, which all sound overly warm in my Studio set-up:
    TH900
    LCD-2.2
    Slants

    Halfway toying with the idea of seeing if a pair of HE1K will improve on the HD800, which still seem a tad closed (less separation) compared to my speakers, as per Mr. Rogers' recommendation, but I'm a little skittish that those high end phones which represent a fair piece of change might end up overly dark in my system as well.

    That's why I prefer amp current mode analog output signal for headphones, because it's versatile to impedance levels and headphone types.

    I'm not going to comment on some of the recent issues regarding the EC Studio, but I will say that I got a good 30 minutes or so to hear @MisterRogers Studio (USB from my laptop -> Regen powered by LPSU -> Yggdrasil SE -> Studio), and it sounded awesome! I know he was running RCAs for the 2A3s, but that's all I remember.

    I really found it hard to fault the amp at all. This combo provided a wide, airy stage, with excellent positioning. Plenty of dynamics across the board and a good sense of heft, power, and control not only in the bass but everywhere. Tone was spot on neutral without any hint of nastiness or a clinical feel, nor was it at all boring or unengaging. Very organic and smooth type of neutral. Very resolving and had no issues keeping up with what the Yggdrasil was feeding it. Very cool how it could not only reveal fine details almost perfectly but also give them a sense of being real. Maybe the fact that I keep putting "very" in front of everything I say is evidence how very awesome I thought this amp sounded.

    My only complaint is the price. Maybe some day I'll be able to afford something like this, but as it stands, $7K+ is a lot of money. This is the opposite of a value amp, but, hey, at least you're not dumping thousands of dollars on something that isn't close to perfect.

    Testing / tuning a balanced unity gain line-buffer for using Yggdrasil / Gungnir Multibit balanced. Bottom line: It works. I'll keep you all up on what's learned. What I've learned so far:
    • Yggdrasil delivers more umph, has more headroom when loaded into 10k.
    • This difference is audible.
    • Even the Yggys that 'work' with Studio are not hearing the best it can deliver (current starved, etc).
    • Active buffer with 10k input impedance into Studio balanced > Yggdrasil SE.
    Ok - casing it up.
