A new campaign for a desktop version of their Geek Out portable DAC/Amp has startes in Indiegogo!

Geek Pulse is a high-definition DAC and 3W headphone amplifier.

Beyond being a rad DAC, Geek Pulse has two ways to get music out of it. First, there's a pair of RCA connectors on the back. Second, it has an amazing headphone amplifier inside that is accessed by a 1/4" headphone jack on the front. Again, this is audiophile approved stuff and it is powerful. It'll push 3,000 milliwatts into a pair of headphones. GAIN SWITCH either on PCB board or Dip Switch at the back.

Starts at $249 for very early backers.
$398 for both Geek Pulse and Geek Out ($199+$199)


DAC ESS Sabre 9018K2M (for now)

Interesting Features:

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.
