Schiit Audio, Headphone amps and DACs made in USA.

The second-generation Fulla is our answer to the question, “What’s the most affordable way I can get into great sound on my desktop?” And by “my desktop,” we mean everything on it. Fulla 2 is ready for your headphones, your powered monitors, your analog sources, and more.

Total Flexibility For Your Desktop

Fulla 2 is a complete DAC/Amp in a single tiny case. Plug Fulla 2 into virtually any USB port, connect your headphones and/or powered monitors, and you’re set for great music. But that’s only the start.

Use it as an amp. Connect your phone (or any other analog source) to the convenient front jack.
Use it as a preamp. Connect to powered monitors or speaker amps using the variable outputs on the back.
Use it as a DAC. Connect to an external preamp or processor with the fixed 2V line outs on the back, or use the variable outputs for convenient volume control as well.
Use it with phones, tablets, or computers with low-powered USB ports. We’ve included a second USB port for power input. Plug in your phone charger (or any other 5V DC source with micro-USB output) and Fulla 2 tells your source it doesn’t need any power.

Top-Shelf Components

Like DACs costing more than 10X this price, Fulla uses the latest AKM AK4490 D/A converter. Coupled with an Alps RK09 potentiometer, high-quality filter and amp stages from Texas Instruments, as well as precision thin-film resistors and film capacitors, Fulla delivers performance far beyond its modest price.

Plenty of Headphone Power

Fulla 2 delivers a super punch, up to 550mW into 16 ohms, together with a vanishingly low noise floor and low output impedance. Or, in English, this means it’s a great match for virtually any headphone.

Designed and Assembled in USA, 2-Year Warranty, Easy Returns

By “designed and assembled in USA" this is what we mean: the vast majority of the total production cost of Fulla 2—chassis, boards, 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. Fulla 2 is also covered by a 2-year limited warranty that covers parts and labor. And if you don’t like your Fulla 2, you can send it back for a refund, minus 15% restocking fee, within 15 days of receiving it.

Audio Precision APx555 report for Fulla 2

Wait a sec! The original Fulla was a little dongle-DAC. This one is nearly half the size of the Magni. What happened?
Reality happened. The reality is that there are a ton of dongle-DACs out there, but most people want a DAC/amp flexible enough for everything on their desktop. So we redesigned Fulla from the ground up to meet that need. That’s why it now has:

A big-ass volume knob connected to a well-matched Alps RK09 pot (like we use in Magni)
A ¼” full-sized headphone output
A 1/8” stereo analog input (so you can use it as just an amp, bypassing the DAC)
A 1/8” fixed DAC output (so you can use it with a receiver or volume control, bypassing the internal amp)
A 1/8” variable DAC output (so you can use it with powered monitors, or an amp without volume control)
USB micro inputs for both data/power and power alone (because so many software and/or hardware companies are incompetent…er, wait, no, we mean because there are USB outputs that are power-managed to the point where they don’t work at all. A second power input allows you to connect your phone charger or other 5V supply and bypass USB power.)

Wait another sec. Are you saying that if I plug my phone charger into the power-only USB input, that means the Fulla 2 tells my computer that it doesn’t need any power?

Yes. Or your phone, or tablet, or any other device plugged into the Data/Power USB port. Technically, Fulla 2 tells your computer or phone it needs the full 500mA a USB2 port can supply, unless you plug in a separate power USB, in which case, it tells your computer or phone that it needs 0mA.

So, also on this USB power thing, does that mean I can use a super-crazy linear supply that costs 3X as much as the Fulla 2 to get better performance?

Go back and read what you just asked. Seriously, just use your phone charger or something.

Yeah, I hear you, but I really really really want to spend a lot of money on a linear power supply that does nothing!

We understand. And you should be free to waste your money any way you'd like. But really, your super-pristine linear supply with the Regurgitson Ultraregulators isn't gonna do anything, since it's running through a switching supply anyway. You know, just like lots of other, more expensive products do...except we tell you this, and don't encourage you to throw money down the loo.

So I can use this with iDevices and Android phones with no powered hub?

Many of them, yes. As long as you have a 5V charger of reasonable quality with a micro USB connector for output. You know, like for charging phones. However, note that Android devices are highly variable—just because they're running the latest OS doesn't mean the hardware is up to the task. Some will need helper software like UAPP.

So I can use this with both headphones and powered monitors?

Yep!

So I can use this as just an amp?

Yep!

Or I can use this as just a DAC?

Yep! Either as fixed or variable output, too.

If I plug in headphones…

It automatically mutes the preamp outputs. See, we’re getting good at predicting what you’re gonna ask. Kinda like autocorrect. But with less embarrassing mistakes. We hope.

Whoa. That’s a whole lot of features! How do you do it for $99 in the USA?

By making tons of them, selling direct, and not being greedy.

So why would I step up to a Magni/Modi 2 stack? Or Vali 2?

More power, more flexibility, bigger wallet, bigger desk—remember, Magni/Modi/Vali combos range from $198 to $418, and cover basic USB-powered DACs to multibit DACs, solid-state to tube amps. Consider Fulla 2 a great way to get into the world of headphone DAC/amps, at only ½ the price of the least expensive Magni/Modi 2 stack.

So is this gonna sound great with my headphones?

For most headphones, yes. There are some headphones out there that are very hard to drive, or insanely sensitive. Check with the headphone manufacturer if you're unsure.

Is 550mW into 16 ohms a lot of power?

Well, you’re not going to arc-weld with it or anything, but it is about 10x the output power of a typical headphone jack on a computer or mobile device.

What comes in the box, besides the Fulla? Do I get a cable with this?

Yes, we supply a 3’ micro USB (to standard USB) cable. Yeah, we know Apple and some other doods are going full-nuts on USB-C. One word: adapters.

What about the 1/8” to XLR, or 1/8” to RCA, or 1/8” to 1/8”, or 1/8” to DIN, or whatever cables I need to connect to my speakers or DACs?

That’s a lot of cables. And this thing is $99. Check out Monoprice for 1/8" to dual RCA cables and all the other crazy cables you might need.

Can I use a fancier cable to get better sound?

You can do whatever you’d like, including dancing by the light of the full moon and making small, non-living sacrifices to the audiophile gods.

No, seriously.

We are being serious.

I’m asking specifically about the cable.

As long as it’s a USB 2.0-rated cable, 2m or less in length, terminated with a micro USB plug on one end, you can use it, sure.

And it’ll sound better?

Probably about as much as taping $100 bills to your headphones. Or sending the $100 bills to us. We prefer the latter.

You’re messing with me!

Just a little.

So what’s Fulla in Norse?

Fulla is a goddess, “bountiful”, and a healer. And if you’re looking to relax to some great tunes on the go, the Schiit Fulla can definitely be a bountiful healer. And that’s not fulla schiit.

The Master Switch

Rob Boffard

"Ultimately, it’s impossible not to recommend the Fulla 2."

"Even if you don’t know the world of amps at all, and you just want something to improve your computer sound, then this is - by some margin - the easiest, most flexible and most effective way of doing so. Its versatility, solid sound and superb design make it highly worthwhile, and we think you’re going to love it. We did."

Digital Audio Review

John Darko

"For the newcomer, it’s a taste of high end audio minus the wallet pain. A DAC, a headphone amplifier and a pre-amplifier for the price of three or four new vinyl records. What’s not to like?"

"Like every single other Schiit Audio product that has preceded it, the Fulla 2 is sharply priced but feels a long way from cheap."

Listening Session as History Lesson, b/w Schiit and Shinola—Together at Last

Stephen Mejias, Audiostream

"With good recordings, excellent recordings, and even with shitty recordings, the Fulla 2 consistently made music—compelling, colorful, fun music. It drove the Shinola Canfields easily and happily, allowing them to sound exactly like themselves, but better [footnote 3]. It did the same for my prototype AudioQuest NightHawks, offering an impressively large, immersive, and seductive presentation."

Schiit Audio Fulla 2 DAC/Headphone Amp

Mike Metlay, Recording Magazine

"The Fulla sounded great, but the Fulla 2 sounds better; this is a really good-sounding unit that drives even the most finicky headphones to high levels with clarity and punch. Everything from my custom in-ears to my old 600Ω AKG K240 phones loved the Fulla 2, and it did a great job driving the Neumann KH 80 DSP monitors in our office studio."

"The Fulla 2 is a high-class audio output system for less than a Benjamin. That’s some impressive Schiit right there!"

Schiit Fulla 2 AIO DAC/Headamp Quick Impressions and Review

Marv Chen, SuperBestAudioFriends.com

"The Fulla 2 actually sounds a lot like the Magni / Modi 2 stack. Maybe 5% less slam. 5% less micro-stuff. 5% less attack. 5% smaller stage. 5% less clarity. You get the idea."

"The volume knob is a godsend. Thank you @schiit! Trying to set volume on Windows UI sliders with a mouse is like steering the Enterprise-E with touch screen panel. The fact is, when the Enterprise-E is in deep doo doo, like in an asteroid field with hundreds of lives at stake, Commander Riker is going to use a fricking joystick to get them out of trouble."
