Switched from Yggdrasil to Gungnir Multibit.

makes sure they both have the new built-in galv. isolation (like the Eitr box)

Based on accounts of the Gungnir sounding more "mellow" than the Yggdrasil, and reports that the latter takes months to deliver, I've switched my order.

Unfortunately, I certainly can confirm the Yggy takes months to deliver. 

Randy-11 -- Could you elaborate?

@OP 
I have a Gungy (non multibit). It is a very capable DAC. I ended up getting another Ayre Codex, which I find to be just a nudge better. I have a sneaking suspicion that the Yggy is pretty comparable to the Codex.
(This is coming from owning Modi Multibit, Bifrost Multibit and Gungy).
Regarding break in:
Yes, Schiit DAC's need some serious time to show their stuff. If you can run it 24/7 for a week, then I think you should be pretty close to the final sound.
Bob

I don't know much more - except that they have upgraded versions of at least some models recently to reduce or eliminate problems from loop currents, something the Eitr box is designed to do

may be able to swap boards on existing ones

@rvpiano,
I would just play music at a low level (if I wasn't listening or in bed).
Heck, it doesn't even know if your listening. Probably more important is to keep it powered on.
Bob

Bob,

Oh, it knows!!!

Seriously though, often, instructions are given to warm up equipment, you must play music and play it loudly.

Richard

RV, I think some of that is bunk. 
At the minimum, I would leave the DAC on 24/7.
At the maximum, I would let it play at moderate levels 24/7.

I definitely noticed my Ayre Codex and Schiit DAC's open up after a few days.
Bob

I should get it in a couple of days.
Looking forward to trying it out!

Got the Gungy Multibit. Wow!  Right out of the box, the sound is a big improvement over my old Theta. I can only guess how good it will sound when broken in.
Big problem though. According to Schiit, there is a "clicking" sound when loading a CD or when manually changing tracks.  Rather than  a click, I'm getting a very loud pop from the speakers which is very disconcerting!  I don't know if I can live with it on an ongoing basis.  I may have to consider the Yggdrasil, but I'm not sure if the pop is there too.

You will/should experience the same clicking with the Yggy. I've been waiting on a Yggy (on order for over two months now). However, I asked (email) their tech support the specific question surrounding the issue you mention, as some others have mentioned the relay noise (clicking) as well. The following is their (Nick T) response:

"The Yggdrasil doesn't trigger on silence itself, it triggers on the loss of signal. If the CD Player outputs silence but maintains the stream that will be fine, however if your CD Player actually stops the stream entirely then you will get the click. Different CD Players behave differently."

Just out of curiosity, what is the benefit of this design to trigger a relay when loss of signal is detected? Never heard such a thing before.

Schiit, in the manual, answers this by saying “yes it does”  !!!

Those Schiit guys seem to be full of themselves. 
Thankfully, they put out a quality product at an incredible price point.
I only get the 'click' if I switch inputs.
Bob

As per Schiit tech support:

"It prevents any glitches from the start of the signal from reaching the amplifiers and speakers."

BTW, my Yggy has shipped!! I expect to receive it later this week!!

Congrats gdhal!   Enjoy!!

Unfortunately, I’ve discovered something unexpected which, for me, is very troubling about the Gungy.
Although it’s very clean sounding, warm and precise, the volume output is several decibels softer than my old Theta, and indeed much softer than my analog stage. This causes me to boost the volume control to where it’s out of the “sweet” range of the amplifier. The result is a lack of fullness in the overall sound.
its not so apparent in pop and jazz, where the output signal is usually strong and constant.  But in classical music which I listen to mostly, it’s disconcertingly weak. Even in pop and jazz, with the volume boosted, I’m lacking in strong bass.

This is very upsetting, because I love the overall qualities of the unit and would hate to give it up.  Either I’ll have to get used to it, return it or buy a more powerful amplifier.
On another Audiogon thread I’ve been seeking suggestions for a new amplifier.
The NuForce monoblocks I have now are 160W each.  I’m afraid the cost of a more powerful quality amp is going to cost big bucks.  (I don’t want to change my  vintage Dalquist DQ 20 speakers which I really love.)
So, I’m not sure if I’m going to return the Gungy.  It’s so enjoyable even as it is.

Thank you @rvpiano

Are you able to avail yourself of the balanced outputs? I'm not sure this would be the case with the Gungy, but often times components balanced outputs run about +6db hotter than the RCAs. And I believe your NuForce monoblocks accepts balanced input.

rvpiano, if I understand your issue correctly, its more to do with the input sensitivity of your amp as opposed to its power rating. The recommendation from gdhal may address this issue since in most source components the output voltage from the XLR outputs is normally twice the RCA., e.g. 4 volt vs. 2 volt, etc., respectively. Good luck.

The XLR on this DAC runs at 4 volts vs 2 volts. 

Since you invested in high quality power amps then you might want to try any of the pro audio style DACs which will have much more powerful output (around 20 volt or ten times your Gungy) 

Gdhal and kalali:
Forgive my ignorance.  I’m more of a musician than a technophobe.
I’m connecting my Oppo player which I use as a transport to the Gungy with an optical cable. I have a vintage Conrad-Johnson preamp which only accepts RCA plugs.  So I guess I wouldn’t be able to avail myself of XLR cable.

Why not contact Schiit and get their input on your problem with the Gungy? 
They might just have an answer.
B

I’ll try that, Bob.
I’m not sure what they can do, though 

This thing sounds fantastic in anything other than classical.
Great in a lot of classical, too.
What a dilemma!

In a previous post I should have said I’m not a technoCRAT, not technoPHOBE.
I probably am the latter.

Your Theta DAC was a pro audio style device. It output 9 volts on RCA and 18 volts on XLR.

You are experiencing the limitation of consumer grade gear.

Pro audio gear generally has much higher line level signal levels which allow the devices to exceed the performance of consumer grade gear (better signal to noise and better dynamics).

Some manufacturers of consumer DACs use pro audio grade designs (like ARC) but Schiit Gungy does not. It has the same output signal level as standard consumer electronics.

Shadorne:  It seems as though ARC doesn’t make a DAC.
I can’t find any.
What companies would you suggest looking into?

If you are using a Theta transport make sure the Gundir will play the first 2 seconds of a cut. My Theta Basic was not comparable with the Gundir!

Thank you peterdamroth.  Sorry to hear that.  
Im using an Oppo player as transport.  No problem here.

Oops - I am mistaken. The new ARC DAC 9 does not have high pro audio output levels like the DAC 8. I am puzzled why they changed this aspect of design. The DAC 8 has high output from the analog XLR.

I can’t nearly afford it anyway.

I’ve discovered, to my surprise, that raising the volume control of the amp to unfamiliar levels does not degrade the sound as I thought.
I just have to get used to 11 o’clock vs. 9 o’clock on the dial.

Happy discovery!

rvpiano,

You may discover that your preamp sounds best at or near the Unity Gain volume position if that is specified by your preamp's manufacturer.

I’m seriously thinking about replacing my PS Audio DACIII
with the Gungnir Multibit but the clicking is a concern with 
my Classic Sony CDP707ESD with Kimber D60 coax data cable.

Cincyjim I have 2 yr old Gumby the clicking is ok, clicks only when you push play on transport and when it stops playing the cd... very good dac

@jayctoy
Thanks for the info on Gumby
my concern is I have older CD player it was Sony’s top of line in 
88’ I never had to service it 
i brought it out of storage to replace a Arcam CDP36T it failed me after 2yrs so I hope the Sony works well with Gumby.

I had the Gumby and loved the sound.  My digital source is a Mac mini going to an Audiophilleo 2 USB/spdif converter with battery. The only reason I sold the Gumby was because every time tracks changed or there was a temporary loss of signal, I would get the click sound. This was absolutely unacceptable to me. It was a shame because I really liked the DAC.
Maybe it was a blessing in disguise because now I have the Metrum onyx. It's my fifth Metrum over the years and I absolutely love it.
