  1. m-i-c-k-e-y
    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.

    Outputs?
     
    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.

    Interesting Features:
     
    1. Fully Balanced
    Fully balanced internal circuit.
     
    1. 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.

    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.

    Benefits of a Linear Power Supply
    1. No switching power noise!
    2. Unlike a battery, no need to recharge.
    3. 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) .

    Very excited.  I just really hope they don't stick with shiny acrylic for the faceplate.  A gain switch would also be crucial so that more sensitive headphones and IEMs could be used with the 3W headphone out.

    Anyone know the expected release date for this? 
     
  4. m-i-c-k-e-y
    Campaign will start 29 October midnight (Pacific). Delivery will be April 2014

    Ahhh.  Thanks

    Wait, tonight or tomorrow night? I am assuming tomorrow night.

    is this sabre?


    :)

    +1 on both of those.

    That faceplate has a good dollar store aesthetic

    subbed. looking at the back, it appears to use an external PSU, hopefully linear and not SMPS. However, this could make a sweet little transportable setup to run off a battery pack :)
     
  10. Zoo Animal
     
     
    It will be SMPS, they have plans to release a LPS of their own later.
    I like the idea of low cost and upgrade path being up to the user. They also have a battery option included if they make funding goals.

    It sounds like they are also planning to use the same Sabre dac chip as their Geek Out. 
     
  11. brunk
    OK cool, atleast they give you options to "soup it up" a bit :)
     
    I'd like to make two requests though. Please put the power switch in the front and  please please please do NOT make that blue LED a retina burner. Thanks!

    Already in for 2 plus hopefully the battery pack. Also got a Geek on order.
     
  13. Exesteils
    And we're live! Anyone who's getting it, feel free to PM me for a referral. :wink:

    In for one. Halfway to their goal in :30 and surprising few perk levels choosen. An awful lot of $199 and $239 'donations' though. Wonder what that could be?  [​IMG]
