Excited for this as a dac.  The only thing I don't get is the smps wall wart.. isn't that only for super low end cheap stuff?

Almost as bad as using USB for power ?

There are many ways to skin a cat.

 

There is a linear P/S coming.  They may also sell an SLA battery as an option.

SMPS is pretty common for that price point, whether it is internal or an external type. Schiit Bifrost and Peachtree DAC IT are in the same.
Cool that they will be offering an in-house/optimized LPS as an option for it though.

Well I hopped on this at the early bird price.  You'd think with how many hours I browse head-fi every day, I'd have known about this early enough to get into super early bird but I guess you can't read every thread :P  Main thing that drew me to it is the positive reaction to the geek out in the head-fi meet threads and the emphasis on having a good usb input, since that's my input of choice.  Also supporting every bitrate and dsd, I feel like that's what I need to upgrade from my hifimediy dac which seems to do everything I need it to.  

 

I guess having the external PSU is a good choice because they can use a smaller enclosure with less heat generated by the psu being inside and that saves money for other components

Hey guys,

Would like to know does geek pulse accept DSD DoP over the SPDIF connection...?

Thanks,

More on USB receiver of Pulse:

 

LH,

What USB receiver is being used in the Geek Pulse? Is it XMOS and are you using the Thesycon driver?

Thanks,

Gery

It's XMOS. And Yes, we will use Theyscon Windows Driver.

Ordered!  Waiting patiently :)

 

I guess Geek Pulse doesn't need the USB power from the computer right?  Is it possible to add a small switch to disconnect the USB power from the computer?  Or maybe just disconnect the USB power pin permanently since they are not required for Geek Pulse to operate?

 

Some people said it will lower the noise hence improves the sound quality.

 

Thanks!

To confirm your statement, in the LH Labs forum Larry indeed said that Geek Pulse doesn't require power from USB for operation. It uses its grounding though.

The only time it uses the 5v is during its handshake operation.

Larry suggested a DIY switch to cut off power after handshake.

In that case, maybe a relay, controlled by the system to cut off the usb power would be better :-)
Whenever the dac need a handshake, the system set the relay to connect the usb power, and disconnect when no longer required.

We've changed the $350,000 and $500,000 stretch goals according to your requests. Thanks Geek Force!
