I am cleaning out some stuff from the storage cabinet because I can use the cash for a new amp.

If you are reading this, you probably know the checkered history of LH Labs and its scam crowdfunding.  You may also know that I was one of the crowdfunders who assembled the infamous complaints to the California AG's Office and the Federal Trade Commission.  See this thread for some bedtime reading: 

The saddest part of the LH story is that the products that LH actually delivered were good.  I was one of the lucky few who received a VI DAC and it was one of the best I ever have used in my main system.  This Geek Pulse Fi DAC, which is a mid-level model upgraded from the basic, RCA-only version, sounded quite good in a desktop system playing from JRiver with Windows drivers.

There was no manual and the LH Labs website is history, so I found it difficult to get specific details for this ad.  Here is what I found in another reseller's ad from a few years ago. It purported to be from LH's advertising at the time:

"LH Labs Website:  Description & Specifications

"Geek Pulse is the world's most powerful 32/384 kHz + DSD128 desktop DAC and 3000 mW headphone amplifier.

"Geek Pulse is Designed to be Different. Instead of just barely getting the job done, it goes the extra mile to get the job done well. Very well. So well that there's no other DAC that can do what it does without having to pay three times the price.

This unit includes a femto clock upgrade and another upgrade package for which I no longer can remember or ascertain details.  I have the original packaging and power adaptor.  I also will provide a disc with Windows drivers as they no longer are available, although I recall being able to use this with Windows standard ASIO drivers.  (I no longer have the included USB cable. I can include a generic if you need one, but I used upgraded ones and you will want to, as well.)

God only knows what the MSRP was, since most of LH's price advertising was complete fiction.   I was in at about $500 or so, including postage, for this unit. 

Prefer to sell in lower 48 USA, but will ship overseas.  Buyer pays postage and 3% for PayPal unless you use Friends and Family. 

This, with two of my other DACs, is my first listing here, but I have sold some things at Audiogon under the username MikeRubin.  Check feedback there.
