Geek Pulse is a high-definition DAC and 3W headphone amplifier from LH Labs that was crowd-designed and crowd-funded on Indiegogo. Since its launched, word has spread quickly and Geek Pulse has become the most successful crowd-designed high performance audio component in the world.
Geek Pulse decodes both PCM (the most common music format, the one used in your CD's and MP3's) and DSD music files (a rapidly-growing digital download format that audiophiles tend to love). It uses a converter that can convert bit rates of 1 bit, 16 bit, 24 bit, or 32 bit. It decodes sample rates of 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, 192 kHz, 352.8 kHz, 384 kHz, 2.822 MHz, 3.072 MHz, 5.644 MHz, and 6.144 MHz
What input can we connect it with?
Geek Pulse has several digital inputs, whether it's a server, and computer, a CD transport, or a smart devices like iPhone/iPad and Android phones?Tablets. It has one USB 2.0 input, two S/PDIF RCA inputs, one TOSLINK optical input, and one AES/EBU balanced input.
Geek Pulse has two ways to get music out of it. First, it has a world-class headphone output that puts out 3,000 mW through a pure class A amplifier into your headphones. Second, it has line level outputs for you to connect to your home stereo. Standard RCA for the base Pulse and additional XLRs for the Pulse X.

Geek Pulse differences
- Fully Balanced
Fully balanced internal circuit.
- The 3D Awesomifier
Geek Pulse's 3D Awesomifier electronically duplicates what happens naturally when we listen to sound through a stereo. Sometimes this technology is called "crossfeeding," but Geek Pulse does it in a very unique way, using both digital and analog technologies proprietary to LH Labs.
Super Quiet DC Power Circuit
Since Geek Pulse isn't USB powered (like Geek Out is), we'll make "Da Vinci magic" again with a quiet and proven super regulator that uses a large bank of capacitors, providing the best power supply in its class.
- Femto Clocks
New Addon Products
Geek Blue is a Bluetooth 4.0 addon with the aptX codec so you can stream your tunes from your Android, iDevice, and any other Bluetooth-compatible device.
Geek LPS and LPS4
Geek Pulse has a friend named Geek LPS. LPS stands for "linear power supply." If you really want to get the most out of Geek Pulse, Geek LPS is a must.
Geek LPS takes dirty AC power from the wall and delivers clean DC power to Geek Pulse. This clean DC power has very low noise, which improves the sonic quality of the music coming out of Geek Pulse. With clean power, you get more natural music.
As an added feature, Geek LPS can be used to clean the noise off of the USB connection from your computer to Geek Pulse. Just connect your computer to Geek LPS using a USB cable, then connect Geek LPS to Geek Pulse (or any USB DAC, for that matter) using a second USB Cable. When you do this, Geek LPS disconnects the 5V power coming over the USB cable from the computer and replaces it with clean (under 6uV noise) 5V power coming from its super-regulated power circuits.
Geek LPS4 (4 outputs)
Benefits of a Linear Power Supply
- No switching power noise!
- Unlike a battery, no need to recharge.
- Unlike a battery, a LPS has excellent system grounding.
Special note: If you live in a country where your power is not one of the ones specified (Japan or Brazil, for example), please don't buy Geek LPS. Also note that the 110V/120V and 220V/240V is jumper switchable (inside) .
Will update periodically.
Just here for the music.
