Schiit Happened: The Story of the World's Most Improbable Start-Up

[ArmchairPhilosopher]

@ArmchairPhilosopher What triggers the protection circuit in the Valhalla 3? Is it just current, or something more sophisticated?

Please contact support if you think your Valhalla 3 trips a bit too easily.

The sooner we (collectively as audiophiles) can instead ask, "Did you enjoy that?" the sooner all this schiit starts to make sense.

A big part of what my local group does is to teach people to listen without knowing brand or price. If a Schiit DAC does well and folks learn after it beat out more costly units ( and they have) then so be it. It also teaches people a small improvement that costs $3,000 more may not be a feasible price to pay. The Stjarna is a fine example of that. IMHO

I do admit I like some brand names better than others but they should indeed have enjoyable sound. One is Latin for craftsmen of sound, another is Italian for first moon.

I have several versions of DSOTM.

My favourite on CD is an early one with a Harvest label which cost about £5 on eBay!
I much prefer it to a later remaster.

First pressings on vinyl are worth big bucks.
An old friend has one which he bought when it was released in 1973!

I recently bought a 30th anniversary remaster on vinyl which some think gets close to the first pressing at a fraction of the cost.

It was cut from the original analogue master tapes.

I also have a 50th anniversary vinyl pressing which was a lot cheaper and sounds pretty good.

I appreciate that Floyd have their detractors, but I still regard DSOTM as a timeless classic.

I have rips of the Analog Productions SACD, the 30th Anniversary SACD, and MoFi Gold CD of DSOTM. I haven't A-B'd them back to back enough to declare an outright winner but I LOVE that Gold CD. In fact, all of Pink Floyd on Gold CD just has a certain addictive heft and punch to the sound quality - those Golds have certainly been instrumental in turning my opinion of PF from a fairly negative view to a pretty healthy one. Took most of my life but I'm finally managing to 'get' Pink Floyd.

I think it's Marilyn Manson music.

Just back from a yard sale, the widow of an audiophile hosted it. I acquired some early Savoy Brown, Springsteen, and a master recording of Jackson Browne’s The Pretender on vinyl. All records in amazing condition.

Was there any equipment for sale? Good catch on the vinyl !!!

 

[Adam Balm]

Oh my...Mimir.
If only my ears could smile.

 

[sixergixer]

Going to see Victor Wooten and the Wooten Brothers tonight. Should be a heckuva jam.

 

[Syan25]

Tonights album.

Bernstein and VPO are amazing in the "Jupiter." It has this ease and finesse to it. The contrapuntal nature of the work comes through with clarity and warmth. It's truly a great interpretation.

 

[Paladin79]

No but I always ask. She sold that after her husband died. He knew Amar Bose and owned Bose 501 speakers. Fortunately my son will take over my audio collection because like this lady, my wife would be lost. Trying to be kind and not too cynical I just said Bose was probably more respected at the time her husband had those speakers.

 

[Ripper2860]

501s were probably my favorite (as in least offensive) Bose speaker. IMHO, YMMV, etc.

 

[MindBreak]

My NOS tubes for the Valhalla 3 arrived early.

 

[docBliny]

Nope, just the switch in the back.
As soon as the wall wart's power goes away, the circuit switches over to USB power. And it's entirely done through the circuitry itself, not firmware.
Depending on your source, you might be able to configure it to not supply any power to the connected USB device, but that's usually not a thing you have any control over with most operating systems.
You could also put a powered USB Hub between your source and Mimir and switch off power to that USB hub when you remove Mimir's power. That way both supplies go down and Mimir switches off.

Thanks,

I tried the only leftover hub I had, but unfortunately that passed the power through even when unplugged (though not fully reliably). I also tried preventing +5V on the USB A side, but Mimir isn't recognized in that state (as it shouldn't).

I'll use some electrical tape for now - Mimir will join several other things in the bedroom to get that treatment.

I do admit I like some brand names better than others but they should indeed have enjoyable sound. One is Latin for craftsmen of sound, another is Italian for first moon.

Don't forget another that is a German phoneticized spelling of an English word for excrement. Not quite as poetic.

Not saying this will work, but...

2025, Chapter 5
The End of the DAC As We Know It

This is going to sound like a joke.

It’s also gonna start a lot of jawing amongst the crowd who think that there’s nothing to DACs other than stuffing the “latest and greatest” off-the-shelf chip in a box.

So, to jump right in:

Mimir is here. The first Mesh™ DAC. Also a full Forkbeard™ digital preamp. Also with Unison 384™. Also with Linear Override™.

Oh and it starts at $299.

“Wait a sec,” half of you are asking. “What the heck is a ‘Mesh DAC?’”

“And hold just a motherflippin minute,” half of you are crying. “Digital preamp? What the heck do you even mean by that?”

Har. Har har.

Boom.



Mesh™: ComboBurrito’s New Recipe

Let’s talk about this whole “Mesh DAC” thing first. Because, even without considering Forkbeard, Mimir’s a very big deal.

Those of you who know us, know that we have our own digital filter, based on our own math, implemented in costly DSPs, for use with multi-bit D/A converters. This unique digital filter is what Mike Moffat has referred to as his “megacomboburrito” filter in the past.

Silly name, yes, but it does accurately describe what we have: the only time- and frequency-domain optimized, closed-form digital filter. Unlike other approaches that are content to resample the recording, without concern for retaining the accuracy of the original, we concentrate on preserving the original samples as far as possible.

Aside: hence our new ads: DACs for the recording, not the re-sample.​

​

Aside to the aside: yeah I know some of you guys use upsamplers, that’s fine, there is no One True Path to audio nirvana, but we do believe in retaining as much of the original is important, and should not be lost in a quest for higher and higher rate transformations that may not have any relationship to the original.​

​

Aside to the aside to the aside: ya want change? We gave you a parametric EQ here. Also in Gungnir 2 soon. Have fun. That reaaaaaaaallllly changes stuff. No question. No problem. Enjoy.​

Anyway, the megacomboburrito filter had only one problem: it was expensive. It used costly D/A converters, pricey DSPs, required complex power supplies, and in general wasn’t budget-friendly. We eventually got Modi Multibit down to $249 to start, $299 in Gen 2 form, and, if we kept it going, it’d need another bump to $349 to cover increased production costs. And $349 for a relatively limited, single-ended-only product wasn’t really something I wanted to pursue.

So I started asking the digital crew, “Can we combine our megacomboburrito filter with a standard delta-sigma modulator?”

The idea was, of course, to figure out a way of retaining our filter’s inherent goodness, while making a more affordable product.

“But the DSP,” Dave said, as soon as I proposed it. The DSP was where we’d gotten the horsepower to run the filter in the past.

“Can we do a version of the filter in the Unison USB chip?” I asked. We use a very powerful 32 bit Microchip microprocessor for our own USB interface. It seemed like we should have enough capability and precision there.

Dave looked skeptical. “I/O is a problem. But if we’re going to be using a standard audio DAC, maybe.”

I crossed my arms. Because I knew the answer. Theta Digital, Mike’s first foray into DACs, had combined an early version of our digital filter with a delta-sigma DAC…in the 1990s.

Dave looked uncomfortable. I knew he didn’t like the idea all that much, because it blurred the lines between True Multibit/Multiform and delta-sigma. And also because it was more complex than I expected.

“We have Unison USB,” I prodded. “If it can do more than USB, that’s a huge win.”

Some uncomfortable glances were exchanged between Dave and Ivana. I was also pushing for more Unison USB capability, specifically Unison 384, and this was more work on top of that.

I let the silence stretch out.

“It’s worth looking into,” Mike said, finally.

And that was how we started looking at Mesh.

Now, “looking at,” isn’t “doing,” so it took a few more reminders to get Dave and Ivana to understand I was serious.

But when we started really working on it, we found:

• It was feasible to do a version of our digital filter on the Unison USB microprocessor. This completely eliminated the need for a DSP, which saved a lot of cost.
• Nothing is free, so we took a power hit. The microprocessor had to run faster. However, by running it faster, we had it operating comfortably below its processing limit. And, with the addition of a Linear Override power supply, we were able to retain Mimir’s capability to run on USB power.
• Having great familiarity with a standard delta-sigma modulator (in this case, an ES9028) paid off in implementation. Many have already commented on Modi and Modius outperforming “newer” ESS chips, thanks to parts whisperers like Dave. The deep familiarity we had with the “older” ESS chips allowed us to make Mesh, well, “mesh” much better than we’d hoped.

The result?

The Mesh DAC sound shocked all of us. Even Mike Moffat declared that is was far, far better than he’d expected. It’s nothing like a typical ESS implementation. It retains a whole lot of what makes the “megacomboburrito” DACs special.

In retrospect, maybe we shouldn’t be so surprised. The Stereophile review of the Theta DS Pro Prime, Mike and Dave’s first product to meld a DSP-based digital filter and a standard “bitstream” DAC, commented that it sounded much more like the other Theta products than a delta-sigma device.

Aside: Mike and Dave did the DS Pro Prime for the same reason we did Mimir—to make their products more affordable. And I think it’s important to note that the DS Pro Prime was considered a super, super high value at $1250 when it debuted in 1991. In constant dollars, that’s $2906 today. ​

​

Aside to the aside: Go back and read that again. Two thousand nine hundred six dollars. Mimir is only about 1/10 the cost. For a much much much more capable DAC. ​

​

Aside to the aside to the aside: This is what you call “progress.” ​

This is a big deal.

Mesh makes implementing our filter much simpler and more affordable. And this affordability allowed us to do a whole lot more than we expected with Mimir.

Specifically:

• We included Unison 384. AKA the new high-rate Unison USB. Now you’re covered all the way up to DXD rates. As in, pretty much all music on the planet. And, with Mesh, we’re keeping the recording as original as possible.
• We added Linear Override. Linear Override debuted in Gunnr, as a way for us to give you easy transportability and high power output. Plug in the included AC wall-wart, and Linear Override, well, overrides the internal switching supplies with a linear power supply, increasing rail voltages from +/-5V to +/-12V and increasing output from 3V RMS on the balanced outputs to 4V RMS.
• We included independent balanced and single-ended outputs, as well as a suite of inputs, including transformer-isolated AES and coaxial.

So yeah, Mimir is a fundamental transformation in our DAC capability, bringing a completely unique filter with proprietary math to a platform that can extend down to our least expensive products—oh yeah, and is based on our own unique Unison USB architecture.

Oh yeah, and it is updatable over the air, like Gungnir 2.

Aaaaaaand….remember that we still had processing power left in the Unison microprocessor?

Yeah. I wasn’t about to let that go to waste.




Full Forkbeard Ahead

I’ve heard some comments from people who wonder why we haven’t been pushing the Forkbeard platform especially hard, given the “groundbreaking” pronouncements I used when we launched.

Like most of the things we do, there’s a good reason we’ve been relatively quiet.

Here it is: until now, you haven’t seen what Forkbeard can be.

Because, with Forkbeard, and that unused processing power of the Unison microprocessor, we can transform a very nice DAC into a complete digital preamp, including remote control, digital volume, (with balance!) and a parametric EQ.

For $50.

Oh yeah and in June, we’ll be adding the same features to Gungnir 2, including a more capable 5-band parametric EQ (thanks to the additional processing power of its DSP).

Free.

Go back and read that again:

Gungnir 2 will soon be a full digital preamp and EQ.

As a FREE UPGRADE.

Do we have your attention now?

“Wait a sec, are you saying I can add a Forkbeard module to Mimir, then plug it direct into an amp, and have a complete system, with volume control and EQ…without an external preamp or EQ?”

In short, yes.

“Well, that’s crazy,” someone is saying. “You could easily charge for that upgrade. You’re not maximizing your customer lifetime value. You’re not serving your shareholders to the fullest extent!”

Yeah, we’re also not assholes.

And, hey, I’m the majority shareholder. And I don’t give a ****.

There are way too many companies hellbent on squeezing every cent out of everyone for everything. We don’t need to be one of them. So, again, with feeling: every update to Forkbeard will be free. Period. Even one as seismic as this.

“Well that’s still 100%bonkersnuts,” someone else says. “You guys make preamps and EQs. Aren’t you just cutting yourselves off at the knees?”

Also in short, no. Analog preamps and EQs still have their place. We’ll get into that a bit more later.

But also, we’ve never been afraid to eat our own. We’re never worried when we come up with a less expensive product that’s better than a previous flagship. We laugh when a reviewer says, “no, this is too good, seriously.”

We always do the best we can.

Period.

Even if it’s a game-changer.

I forget when we came up with the idea to add digital volume and EQ to Mimir. Maybe Martin remembers. I don’t know if it was based on the fact that we had extra processing power, or if it just seemed like a good idea in theory, or if it started with Mimir at all.

I know it was formalized last year, when I delivered a “wish list” for Mimir that I expected to break Dave and Ivana. It included:

• Mesh DAC
• Linear Override
• Full remote control
• DAC reporting (sample rate, etc)
• Volume
• EQ (of some kind)

The amazing thing was…they went beyond that.

I didn’t expect parametric EQ. I mean, yeah, 3 bands doesn’t seem like a ton, but for a parametric EQ, it should be plenty to tune any system.

Aside: yes, you can get too crazy with EQ. If you need 30 parametric bands to correct your room, maybe work on your room. Or smoke a doobie. Because you can get wayyyyyyyyyyyyy too nervous about this stuff.​

​

Aside to the aside: the best EQ I personally ever used, prior to Schiit, was a 3-band non-parametric analog EQ with well-chosen bands. This was in the car stereo days, which have a lot more problems than a typical home system.​

​

Aside to the aside to the aside: Dave really was running out of processing power in the end, and still delivered far more than I expected. If he figures out how to get a 40-band X-Tra-Kray-Zee edition EQ stuffed in there, you’ll be able to do OTA updates to get it. Or maybe best not to. I’d prefer not to see you in the asylum.​

They also gave me phase inversion and Mesh filter/NOS filter switching on the Forkbeard interface.

“NOS?” I asked Dave. “How does that work?”

“It just repeats the sample, no filtering.”

“Straight to a delta-sigma modulator?”

Dave nodded.

Hmm. That was weird. But also OK. Because it gives you another option. Go ahead and resample. Run that straight to the ESS delta-sigma modulator. And see what you think. Or hear what you think. You get it.

“Volume?” someone asks. “Digital volume?”

Yes. So let’s have that discussion.

Let’s start by getting this out of the way: no volume control method is perfect.

Zip. Zero. Nada.

They all have pluses and minuses.

If you are stumping for one method over another like some pamphlet-slinging zealot, you’ve probably ingested too much marketing. Time to take some deep breaths, do a detox, and come back when you’re feeling more grounded.

What kind of pluses and minuses we talking about? Let’s look at three examples:

• Analog potentiometer.This is what we use on Magni, Jotunheim, and many other products. It’s a pair (or a quad) of continuously variable resistors that are used to divide the signal down. Sounds simple? It is. Unfortunately, it also has some significant drawbacks.
  • Pluses: easy to use, can be relatively inexpensive
  • Minuses: channel balance isn’t perfect at low volume levels, variable impedance means variable noise floor that maxes near mid volume
• Analog relay stepped attenuator.This is what we use on preamps like Saga, Kara, and Freya. This is our preferred way to do volume, but it’s not without its drawbacks.
  • Pluses: basically perfect channel matching, fine control with linear steps
  • Minuses: complex, requires relays, many different resistors, and microprocessor controls; impedance still varies with position
• Digital attenuation.This is what we’re giving you with Mimir and (soon) Gungnir 2. You also have the option to completely defeat it. Because, while the idea of a “pristine” digital volume control sounds good at first, it also has its pluses and minuses:
  • Pluses: can be very inexpensive to implement if you have the processing power, output impedance not variable
  • Minuses: digital volume means math. Math means altering the samples. Below a certain level, you will lose bits—or, in other words, lose resolution.

“Losing resolution? That doesn't sound good,” some people are saying. “Why would you even give us this option?”

“Ah come on, I hear there are “perfect” digital volume controls out there,” say others. “What, does yours suck?”

“What about autoformer and LDR volume controls,” someone else asks. “I hear those are fantastic!”

Yeah, I expected this. So let’s break it down.

• Why did we include digital volume? Simple: because it’s a really good option for many systems, and it’s great to have the flexibility. For all the jawing about the downsides to digital volume, the reality is that a well-tuned one (like we have on Mimir) is actually very nice, and quite transparent down to very low levels. Plus, you can defeat it if you don’t want to use it.
• There are NO “perfect” digital volume controls. If you believe there is a magic digital volume, you have been consuming too much marketing. The reality is there are very bad digital volume controls out there. Hell, Mimir’s wasn’t fantastic before we tuned it. What we ended up with was a really nice volume control, based on our experience of over 40 years in groundbreaking digital audio. And, if we come up with something better, Mimir has over-the-air updates.
• What about autoformers and LDRs? Sorry, I don’t have enough experience with each to comment in detail, other than noting that autoformers are probably going to be expensive, and LDRs are not champs on the distortion front. If you have one of those and love it, cool, but we won’t be competing on that dance floor.

“Well, what about digital EQ,” someone says. “You’re using math there as well. You’re changing things!”

Yes, and that’s the point: if you choose to change things, we give you the capability to change things.

We’ve also carefully tuned the EQ, based on our own algorithms, to get it to be as sonically innocuous as possible. We’ve also carefully chosen the boost and cut ranges to maximize the dynamic range and minimize impact to the overall output level.

Aside: “lossless” digital EQ? Sure. Yeah. Whatevs. You’ve lost every single original sample as soon as you start EQing, period, full stop. As long as you’re OK with that, it’s all good.​

But I think, in terms of both digital volume and digital EQ, the point is that these are both optional.

Don’t want volume and EQ? Don’t use them. They won’t affect a single sample.

Don’t want the chance of ever using volume or EQ? Don’t bother with Forkbeard at all. Mimir will just be a great DAC, and nothing else.

But if you want to go preamp-less to simplify or save, or if you want to make some sonic tweaks to address your room or your headphones, you have the capability.

Oh yeah, and you get even more. I didn’t get to all of it.

Like Loudness.

If I could go back in time and take one control from all the 1980’s stereos, it would be loudness. Loudness, or Fletcher-Munson equalization, is a way to compensate for how your ear perceives low volumes.

If you’ve ever noticed how a recording sounds thin and lifeless at low volume, you’ve experienced the Fletcher-Munson curve. You’re not imagining things. Your ears are actually less sensitive to bass and treble at low levels.

On many stereos in the 1980s, there was a button, labeled LOUDNESS (which was always pressed in), which tweaked the output of the system to have more bass and treble at low volumes, and gradually become more flat as volume increased.

These buttons were always pressed in because it sounded good. Especially when listening at low, background levels. It was a very useful control. And simple. No tweaking 31 EQ bands. No knobs. Just a button. No nervosa, just better sound at lower levels.

Which is why I stumped for including it on Mimir. Try it and see whay you think.

Aaaaaaanndd…Balance.

Yes. Balance.

Because, even though you should fix your room first, you may not be able to fix your hearing. Or, if you love your significant other enough, you may not be able to fix your room, entirely.

And also because balance is one of the things that makes the most sense to do in the digital domain. Balance should be a relatively minor adjustment. You won’t need more than 3-6dB in most cases.

Aaaaaaannnnddd…phase invert.

Absolute phase inversion is another thing that’s perfect to do in the digital domain, because it’s one of the most simple and innocuous transforms out there. With Mimir and Forkbeard, you also get one-touch control of absolute phase inversion.

Try it…it sounds very different. It’s very easy to hear if you have a recording that’s out of phase.

Aaaaaaaannnnnnnnnnnnndddd…over the air updates.

Although we think Mimir is perfect right now, and will be perfect forever, who knows? Maybe we will find a way to give you more EQ bands, or better algorithms. Or, in the case of a Forkbearded system, we may add features like control macros. While macros and stuff like that are simply a part of the Forkbeard app, we can also improve the internal code of Mimir over time, without SD Cards, EEPROMs, or, even worse, sending the whole thing in to us.

Aaaaaaaaaaaaaaaaaaaaaannnnnnnnnnnnnnnddd…Visual Volume!

Add a Forkbeard-enabled amp from the $299 Gjallarhorn F to the $1999 Wotan, and you have a full Visual Volume system with only 2 components. For those of you wearing the green visors, that means $299+299+100, or $698, gets you a helluva integrated DAC. preamp, EQ, and amp!

Go back and read that again:

• 4-input DAC with custom USB input, AES input, and digital filter
• 3-band parametric EQ
• Volume and balance
• Forkbeard-enabled Continuity S™ speaker amp

For $698! Made in USA!

Beginning to understand the full scope of Forkbeard now?

Yeah. This is a big big biiiig biiiiiiiiig deal.




About Preamps

Let’s get back to everyone who’s worried we’ve just wrecked our preamp market. Remember I said there were good reasons to stick with an analog preamp? Yep!

The bottom line is that most super-serious audiophiles will be best-served by an analog preamp using the best volume control on the planet, the relay ladder attenuator. As in, Saga 2, Kara F, or Freya+ F. These devices, ranging from $279 to a bit over a grand with all the trimmings, enable:

• The best, finest, lossless control of volume
• Output mode selection, including the option for passive control, or adding gain
• The ability to seamlessly integrate analog sources, such as turntables, while keeping them entirely in the analog domain
• Control via an IR remote
• Control via physical controls on the front panel

Here’s the thing: Mimir is a really good digital preamp. But it is digital. There will be resolution loss at some point. It may be nothing you ever hear. But it’s there.

Mimir’s preamp capability is also entirely via Forkbeard. There are no physical controls. As long as you’re content using your phone to run everything, you’re fine. If not, you’ll want something with knobs and buttons.

So can you get by without a preamp? It’s entirely up to you.

And now you have the choice to go analog preamp-less with Mimir.

Aside: oh yeah, and with Gungnir 2 in June!​

​

The EnMeshed, Singular™, Great Bygg Future

So here’s where we get to the usual questions about whether or not everything will end up using Mesh, and what about our other DACs, especially Yggy, which hasn’t even gotten Forkbeard yet.

Well, with respect to Mesh, of course we’ll be looking at bringing that down the line to other Unison USB products. The whole point of Mesh is bringing a big part of our unique technology—the megacomboburrito filter—to much more affordable products. However, it’s not just a firmware change, it’s a redesign. So, we’ll see.

On the other hand, bringing Mesh up the line maybe doesn’t make a lot of sense. We already have our multibit DACs that use precision, bit-perfect D/A converters to preserve the original samples.

You will see casualties: both Modius E and Modi Multibit 2 ride into the sunset, replaced by Mimir. We’ll sell them while we still have stock, but they’ve really been eclipsed by this new DAC.

And, finally, with respect to Yggdrasil, we’re taking the unprecedented step of pre-announcing details of the Yggdrasil Singular, AKA Byggy, and enabling current Yggdrasil owners to sign up to be first in line for upgrades this summer. There’s even a free upgrade option for everyone who bought an Yggdrasil from us. The reservation page will be up tomorrow.

We hope you enjoy Mimir!

@ArmchairPhilosopher @Jason Stoddard And how exactly the digital volume control works? My non-educated guess is that if you change 16 to 24 bits and only then do volume control the information loss should be zero or about zero. Or ideally, after the full upsample as well. I think if it's done properly, even high end purists with Gungnir will appreciate it....
