STATUS: In stock.  All backorders have shipped.  Orders placed today ship in 1 - 3 business days.

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.
Made in USA, 2-Year Warranty, Easy Returns
By “made in USA,” we mean made in USA. The vast majority of the total production cost of Fulla 2—chassis, boards, assembly, etc—goes to US companies manufacturing in the US. 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.

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? 
So I can use this as just an amp?
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. If you want a definitive answer, send an email to tech@schiit.com.
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.
