Schiit Audio: Audio Products Designed and Built in California and Texas

To improve on Lyr 2, we had to completely reinvent the amp, introduce two new technologies, and make it modular. Yes, that’s right. Not only is the new Lyr 3 a big sonic upgrade, it can be configured with the DAC or phono preamp of your choice—just like Jotunheim.

Power and Finesse in One

Want to run IEMs? Sure. Need power for your HE-6? Sure. If this means nothing to you, just be confident that you can plug any headphone into Lyr 3 and get great sound. With full power delivered from the standard ¼” jack, you don’t need balanced headphones to take full advantage of Lyr 3.

Unparalleled Flexibility

Select from the internal card or rear-panel analog input, and pick high or low gain with convenient front switches. Connect the preamp output to your powered monitors for a complete desktop system—or use it as a front end to your speaker power amplifier. Lyr 3 provides all the flexibility you need.

Single Tube, Two Complementary Technologies

Now, you can enjoy a serious tube amp—that only requires a single tube. Our Coherence™ hybrid topology makes the most out of the supplied new production 6SN7 tube, and also works with all NOS and new-production 6SN7 tube types. What’s more, Lyr 3 introduces Continuity™—a constant transconductance output stage which provides superior performance.

Configure Now, Ready For the Future

Select from two different DAC modules, a phono input module, or no module at all to tailor Lyr 3 exactly to your needs. Modular design means Lyr 3 won’t be dumpster-fodder when technology changes—just swap a card!

ES9028 DAC Module. Choose the ES9028 module with Unison USB™ for a world-class delta-sigma DAC for $100.
MM Phono Input Module. Or, choose the MM phono input module, for 42dB of gain and passive RIAA, for great phono sound, at only $100.

Designed and Built in California

By “designed and built in California" this is what we mean: the vast majority of the total production cost of Lyr 3—chassis, boards, transformers, assembly, etc—goes to US companies manufacturing in the US. Our chassis are made minutes from our facility. Our PCBs are done just over the hill from us, or done in NorCal. Our transformers are also made in California. You get the picture.

5-Year Warranty and Easy Return Policy

Lyr 3 is covered by a 5-year limited warranty that covers parts and labor. And if you don’t like your Lyr 3, you can send it back for a refund, minus 5% restocking fee, within 15 days of receiving it.

APx555 Report for Lyr 3

Hey, wait a minute, this is completely different than Lyr and Lyr 2!
Right. Like we said, we had to reinvent the whole thing in order to improve it significantly.

But…but…but…I have about $4,537 in tubes for my Lyr 2, but now you changed the tube type!

Well, leaving aside the sanity of spending 10x the amount in tubes as on the amp, yes, life is unfair; change is the only constant; you have to break eggs to make omelets, and all those platitudes that you probably don’t want to hear. So, here’s the deal: we changed tube type (from noval, 6DJ8-family tubes, to octal, 6SN7-family tubes) because they sound better and perform better. In fact, the 6SN7 tube family is one of the most linear tubes ever made—as evidenced by the amazing performance of Lyr 3.

But…I’m just not happy with better performance!

We also changed because the tube world is changing. Rolling two tubes is becoming more problematic, as tube prices increase. With Lyr 3, you don’t have to worry about matching two tubes, or the need for two tubes inherently doubling the price of your rolling adventures. Plus, there are some quite decent new production 6SN7s out there, which makes them viable well into the future.

But…I still have all these tubes for the old Lyr!

Yes, and if you want to use them, you can still use them in Lyr 3, with an adapter. Lyr 3’s plate voltage isn’t very different than Lyr or Lyr 2.

Sigh. Okay. I get it. If I’m using one of your preamps like Saga and Freya, can I use the same tubes there?

Absolutely.

Okay, so tell me about these crazy new technologies you’re pimping. Coherence™? Continuity™? What the hell are those?
Cool. Let’s start with Coherence™. This is our unique current-mode, noninverting tube/BJT hybrid topology that eliminates the need for interstage coupling capacitors. These two disparate devices work seamlessly together in this topology, hence the name. Coherence debuted in Vali 2, but Lyr 3 uses an insanely upgraded and tweaked version of the Vali 2 stage. Unlike Vali 2, Lyr 2 has no input or output capacitors, no interstage capacitors, and an overkill 5-pole bias servo.

So what’s this horseschiit Continuity™ constant tranconductance output stage? How is this better than the old “Dynamically Adaptive” output stage?

Whoa, that’s two questions in one, plus an insult. Let’s take this a step at a time. Sit down and buckle up, because this is important—maybe the most important subject for a Class AB amplifier, like, ever.

It ain’t horseschiit. Transconductance nonlinearity in the transition from Class A to Class B is an inherent problem baked into literally every Class AB amp. Take a look at Bob Cordell’s amplifier design book for a great tutorial on the subject. Also, online, reference John Broskie. Both have written many words about the problem of transconductance nonlinearity.
When you bias a Class AB amplifier, both transistors conduct at low levels. When the output goes outside of this low level, though, only one half conducts. Effective transconductance is halved. You can pursue an optimum biasing strategy for Class AB that minimizes this transconductance discontinuity, but it is absolutely there. You can squint your eyes and say that the emitter resistors swamp the effects, but it’s still there. You can use a ton of feedback to squash it flat, but, again, it is absolutely still there. Sumo addressed this with its Transconductance Linearization error servo based on the work of Hawksford and Cordell. This was a complicated way to get around it, but it did work. Another way to address the problem is to bolt on huge heatsinks and crank everything as far into Class A as possible, so the transconductance is always doubled. That’s great, except for the fact you end up with huge, heavy, hot amplifiers.
Our Continuity™ constant transconductance output stage is a serious attempt to solve this problem. It uses both N-channel and P-channel devices on both positive and negative sides of the power supply, all conducting at the same time, and it uses additional devices that linearize the transconductance outside of the Class A bias region. It addresses both the problem of transconductance doubling and of mismatch between N-and P-channel devices.
This isn’t just hand-waving—the Continuity output stage measures 10dB better THD to clipping.
And finally, Dynamically Adaptive output stage, RIP. That was a sliding-bias arrangement that worked well to increase power, but its performance is significantly worse than Continuity.

Well, like, that’s cool and all, but I don’t understand all the engineering.

Hey, you know, that’s your choice. But if you want to start selecting products based on something more than marketing buzzwords, it might be cool to read up a bit more on this. Again, try Bob Cordell. Or not. It’s your life.

So why didn’t you put balanced on this, like Jotunheim?
Because there ain’t no way it would fit. To do balanced (real balanced—don’t assume that every amp with a 4-pin XLR on it is really balanced), you’re looking at two tubes and twice the output stage and a whole lot more connectors. That simply wouldn’t fit. No way, no how. Look at how much transformer and power supply has to go into Lyr 3.

But I want balanced!

Cool, there’s Jotunheim.

Okay, fine. So let’s talk about this modularity. It’s like Jotunheim?

Yep. It even takes the same modules.

But what if I want two modules?

Then you need a chassis that is a tesseract, because we don’t have that much space in this dimension. Talk to Doctor Who.

Can I change the modules myself?

Like all of our products, there are no user-serviceable parts inside. However, if you are a qualified electronics technician, or know a qualified tech, you can order the boards separately, under “upgrades.” They just plug in. But it’s not like you’d want to leave the top off and drop in the DAC card, then pull it out and put the phono card in again, then pull that out and drop the DAC back in. That’s a bit silly.

Let’s talk practicality. Is this quiet enough for IEMs?

Yes, in low gain mode.

And it has enough power for…

…any headphone, yes.

So can I leave my headphones plugged in all the time?

Yes, Lyr 3 has a muting relay which delays output on first turn-on, and mutes the output on turn-off.

Does the volume control adjust the preamp outputs?
Yes.

Can I turn off the headphone outs when I’m using the preamp outputs?

The preamp outputs are automatically turned off when you plug in your headphones. Unplug your headphones to use the pre outs.

You know this sucker runs hot, right?
Yes, though technically it dissipates 12W less at idle than Lyr 2, and about 10W more at idle than Jotunheim. All of these dissipations are well within the capability of the parts we’re using, so there you go.

What happened to the True Multibit DAC card option?
We're constrained on the Analog Devices ADSP parts, so we're afraid those are on hold for a while. Hopefully they'll be back at the end of 2022.

Schiit Audio Lyr 3 – Flexibility

Headfonia.com, Linus

"The Lyr 3 to me is a highly musical sounding device that really gets you into the music again, where you lose all sight of critical listening and just enjoy what is in front of you."

"Take into account the immense elasticity of the product, letting you configure it to your needs, and the extreme output power you will be faced with one tough decision not to get the Lyr 3 when you’re looking for a new affordable desktop amplifier."

"For the price, the flexibility and the sound it is highly recommended and gives every other amplifier of this year a serious run for Best Amplifier 2018."

Third Time's The Charm

The Master Switch, Rob Boffard

"It more than stands up to its competitors in the space. If you’re looking for a good tube amp, one that can handle just about any headphone you throw at it, then the Lyr 3 is an excellent place to start."

A Leap Ahead

Gary Alan Barker, Headphone Guru

"Unlike many tube headphone amps that exhibit the rolled off high frequencies and bottom end that a seeming majority of electrical engineers think is the “tube” sound, the Schiit Lyr 3 produces a true audiophile sound with extreme linearity in both the low bass extending into the subsonic and the upper registers, while retaining the musicality of midrange to tame the occasionally aggressive precision of the Schiit Multibit DAC. Despite the use of a shared tube for both channels, the stereo separation was competitive with many dual mono amps I have heard, and while the soundstage is a bit shallower than I prefer, it does depend a lot on which headphone you listen to, as listening through the Katanas put me exactly where I wanted to be. As to power and dynamic range, I can’t imagine a headphone that the Lyr 3 couldn’t drive easily and produce clean clear concert level volumes for those who wish to damage their hearing. I did find myself listening to higher volumes than I would normally without any fatigue, and could easily get lost in the music for hours."

Schiit Jotunheim Balanced Desktop Headamp / Preamp Lyr 3 Hybrid Headamp / DAC / Phono

EnjoyTheMusic.com, Jeremy R. Kipnis

"While the Schiit Jotunheim and Lyr 3 are both primarily about the getting the most bang for your sonic dollar while enjoying the music in both a refined and glorious fashion reminiscent of old world full sized components, you can also expect to get both that extra aural excitement and total immersive invitation even more with the Lyr 3, thanks to that 6N8S vacuum tube – especially on headphones. It's simply a matter of counting goosebumps, where the Jotunheim is precise, controlled, clear, and delineated far beyond it's apparent price (with sound value rated at about 4 times its price). Yet, the Lyr 3 picks up and improves upon that already fine and tingling sound experience and ratchets it up a few more important notches – especially in the portrayal of holographic space, weight and depth of the recreated soundfield, and gut penetrating dynamic contrasts, especially if given stellar sounding Schiit to listen to."
