Schiit Audio Fulla 2

I bought this little "fella" to get music out of my PC thru USB to drive my Audeze LCD-X headphones.  It did a great job.  But I decided to upgrade to the larger Jotenheim.  Thus the "Fulla" is available for sale.  It is in New Condition, after only sitting on my desktop a short time.  Just enough time to break it in.  

Schiit says: 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.
Schiit Audio Fulla 2 DAC/Headphone Amp Reviews: 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!"
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."
