Light Harmonic Labs, the geniuses behind the Da Vinci DAC have created a desktop version. While it is not quite as powerful as the Da Vinci DAC, it will be the best desktop DACs available.
The Geek Pulse will retail for $499, and save 50% now!

They have created a project on IndieGoGo for it.

Here are some of the higlights:

LH Labs is a team of audio geeks in Sacramento, CA. We manufacture very high-end audio equipment that is sold, mostly, to audiophiles. We are known in our industry as the engineers and builders of one of the best digital to analog converters in the world, called Da Vinci Dual DAC.

And so, let us introduce you to Geek Pulse!

Many people don't know this, but our human ears can't actually hear digital audio. Digital data has to be converted into analog before we can hear it. To do this, we use digital-to-analog converters, or DACs. They're everywhere: in our phones, in our cable boxes, in our computers. Seriously. They're everywhere. The problem with the DACs that we find in all of our devices is simple— they suck! For the most part, they weren't made to handle high-resolution digital data. They just do they bare minimum.

Geek Pulse has an audiophile-grade DAC inside. Check the tech specs below to see the details. But for now, let's just say that it's bad to the bone. It has four inputs on it so you can connect your computer, your CD player, your Blu-ray player, your Sonos, almost any digital player to it! "More digital inputs" was the most frequently requested feature from our previous campaign.

Geek Pulse is a high-definition DAC and 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 (also a frequently-requested feature from our Geek Out campaign) so you can connect it to your stereo or a pair of computer speakers. Choose really good ones, okay?

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. That's enough power to drive any pair of headphones that we know of. You asked for it; we're delivering. Check the tech specs down below for more details.
