Master of Adaptability

The Geek Out 2A model series is a collection of compact DAC and headphone amplifiers that connect to your computer or mobile device through a USB port. Each Geek Out 2A supports full-resolution audio so you can feel closer to your music, no matter the format. It plugs into your computer’s USB port, and replaces its internal sound card with a powerful, ultra high resolution external audio device. Geek Out 2A is 25 times more powerful than the typical computer’s headphone output, and up to 128 times clearer.

Geek Out 2A plays up to 32-bit 384 kHz PCM and up to DSD128 music files, making it the most capable, and most powerful portable audio device on the planet. The Geek Out 2A is available in two models: Geek Out 2A, Geek Out 2A∞,

Geek Out 2A is a portable headphone amplifier and digital to analog converter. It connects to your computer via a USB Type-A interface.

Geek Out 2A∞ The GO2A Infinity comes with THREE Analog Gain Settings – Our Infinity versions feature an extra gain setting at 450mW, perfect for many on-ear headphones. the Infinity model of GO2A comes with THREE Digital Modes – These modes not only change digital filtration settings but also the digital PLL windows of the internal DAC IC and the re-clock jitter removal circuit, along with hardware installed into the DAC.



World is your soundstage

Geek Out 2A is designed to give you the most accurate, real to life, playback of your favorite music. Thanks to its high-resolution capabilities, noise-free background and increased amplification, your music is effortlessly placed on a true to life, three dimensional soundstage. It’s unlike any other portable headphone device out there. So go ahead, take your soundstage with you anywhere you go.

Daft Punk in your living room

One secret of great digital audio is a lack of digital noise. Geek Out 2A doesn’t let noise get into the signal thanks to its regulated bipolar power supply and extremely accurate dual clocks. The end result is real-to-life vocals and amazingly accurate instrument separation.

Sensitive and charming

Just because Geek Out 2A can scream at the top of its lungs doesn’t mean it’s not sensitive enough to whisper into you in-ear-monitors. Adjustable gain settings allow you to perfectly match the output power for your HUGE power hungry cans or uber sensitive IEM’s.

What makes our GO2A special


About twenty-five times more powerful than a laptop or phone’s output jack, Geek Out 2A can drive any set of headphones.


Geek Out 2A is small and lightweight so you can take it anywhere you go, but don’t let its diminutive size fool you. It’s a boss.


Geek Out 2A is the most transparent DAC you can find, supporting PCM up to 32/384 kHz and DSD up to 128 times the sample rate of a CD.

Extreme Control

Geek Out 2A lets you choose between Time Coherence Mode (minimum phase) or Frequency Response Mode (slow roll-off linear). It’s the only portable DAC that gives you this much control. *GO2A Infinity models introduce the Streaming mode for superior clocking of your favorite music streaming sites.


Geek Out 2A fully complies with the USB 2.0 Audio Specification. That means it’s plug-and-play on USB 2.0 devices. We provide a driver for non-compliant operating systems.


Not all headphones are created equal, so Geek Out 2A lets you choose how much power to output: 100 mW for sensitive IEM’s or 1000 mW for large cans. *Geek Out 2A Infinity models have an additional 450mW output to fit everything in between.

What’s new with GO2A

 Ferrari Red Aluminum Chassis:
Call us perfectionists, we designed an entirely new, aluminum alloy chassis; formal name T6061 aluminum.  GO2A’s chassis also features more surface area than ever before to conduct its heat to the air and some well-calculated air flow slots. As a result, GO2A runs at around 30% lower surface temperature than Geek Out 1st Generation.

Single Ended Output:
Geek Out 2A has an improved analog output stage which works with both single-ended and balanced outputs. We absolutely increased GO2A’s single-ended output power, but we’re even more excited about our improvements to the analog stage. The analog stage features new signal path resistors, almost ZERO vibration-introduced noise, and instant power capacitors.

Noise Isolation on USB interface:
There are products on the market which do passive noise filtration on USB power supply and differential pairs; Geek Out V2 had this design. With GO2A we are pushing even further with state-of-the-art filter components, resulting in an even darker background.

Now accepting Reservations for GO2A

LH Labs is launching the GO2A Reservation!

With our V2+ campaign wrapping shipping next week, we are ready to dive into mass production of GO2A! GO2A is our latest and greatest, and V2 customers who took advantage of our GO2A upgrade opportunity are loving our newest tech as much as we are.

Those who did not have a V2 unit to send in for the GO2A upgrade offer have waited patiently, and we are preceding GO2A’s retail debut with an exclusive soft launch for our customers.

Although you may have not had a unit to trade in, we are still offering $30 off the retail price to our long standing customers for reserving with us. Our expected ship out date is scheduled for the third week of November.


I just received my upgraded GO2A DAC today. I just wanted to let everyone know back at LH that this thing is incredible. Majestically Powerful. Oh My God!!!! I never thought that things could be so much better than the older Geek Out V2. The new GO2A is beyond my expectations. The music is so much clearer, with more punch. Instruments are so well defined,the textures are so real, nuances are scary, Micro & Macro Dynamics are amazing. This product is simply outstanding. Pure Genius!!! Congratulations to everyone at LH Labs Thank You Sooo… Much. – M Jones.

LOVE the return to metal casing, solid, heft, polished well. perfecto! plenty of headroom.
can get blisteringly loud with 400S and IEMs. dannnnng mang, that’s some tight bass with kick indeed, the GO2A bass is more defined, less bloat and delivers in more defined space.GO2A has less “in your face soundstage” and is a 1.5 step back, very welcomed and provides better depth and layering, easily noticed in a side by side listen. More inviting and perhaps less fatiguing over time. with CIEM dead black silent background, no hiss. even with max volume, no music playing. GO2A is clearly back as king of the mini USB DAC/Amps. – J Exby.

It is truly a beautiful piece of equipment.  The buttons have a solid feel The sound is beautiful. it seems that on the recordings that I first listened to it is a just a little more relaxed, just as detailed (but not etched or exaggerated). The power output on the lower gain mode seems more robust, being able to drive my high impedance HD 800’s better Overall, I would say that the casework and buttons by themselves were more than worth the price of the upgrade.  Any sonic improvements are just icing on the cake. – R.
