To add to my quote.

  Lets say the power supply regulator is crappy, and there is variations, and not completely DC.  That cannot cause hiss as it should be 60Hz(AC freq) x 2= 120Hz is added.  You will see it on the freq response spectrum.  Thats not hiss.

How does a better power supply decrease hiss?  I thought hiss is amped thermal noise.

[size=10pt]Hello, someone has compared the PCI Soundcard Cantatis Overture 192 with the Nuforce icon HDP DAC?[/size] [size=medium]Are two identical products or the icon HDP is another level?[/size]

I got my UM3X yesterday, and used HDP to drive it.  There was too much hiss.  I guess the output impedance is way too high.  Any solutions to this? ,I've used the ER4S impedance adapter, and it lowers the hiss, but it doesn't sound as good.

Icon HDP is mainly for on-ear or over-the-ear headphones.  earphones are generally too efficient for HDP. 
Ok, you might want to wait for uDAC-2 Signature Edition - volume pot and output resistors tuned for perfection, cryogenic treatment, unspecified energy wave treatment (it is not radioactive, we just don't know what secrete wave was used to improve the sound, sounded like voodoo magic but it works). This is the 24k gold plated version and estimated price should be about $399.

Bling! If this sounds as good as it looks, you are probably on to a winner.

Please excuse the noob question.  But, is it true that if one already has an HDP all you need is an LPS-1?  No need for the LPS-2U-96K?
 


 

The LPS-2U-96K has USB to S/PDIF converter designed to isolate your Icon HDP and other down stream equipment from the noisy PC ground. You get even better performance.
If you have a optical S/PDIF (coaxial still shares the same ground) out from computer, then you don't need the converter.

Pics of the LPS are up on Nuforce's website. Hopefully they are offering a silver casing as well, although I could live with the black.

lol at $400 uDAC

I recently ordered the LPS-1, and I was under the impression that it would be upgradeable via a self-install kit at a later date. Is this still an option for me, or should I not even bother opening the package when it arrives, send it back for a return, and order the LPS-2U-96K model instead?

LPS-1 can be upgraded to LPS-2U-96K  (or 192K when available).  We plan to have some upgrade kits (easily installed with a screw driver) later in May.

Just wondering.. can it be powered with Energizer XP18000 portable battery?

Got confirmation from Jeff at Glassjaraudio that my Sigma 11 Kit ($85) been shipped.  Can wait to start this project and test the result with my HDP.

 

[Armaegis]

Nice. Can't wait to hear the results (if any).

I'm curious to hear also how difficult it is to assemble the kit.  The price sure seems reasonable.

I've been thinking of trying some DIY projects. For the price it might be a good starting place. (I have some experience building circuits from my days of college physics, but it's been awhile.)
