I just upgraded my PC to Windows 8.  Then Nuforce's asynchronous USB driver for DAC-100 no longer seem to work and DAC-100 is not recognized by the PC at all.  Has anyone encountered this problem?  Do you know if Nuforce will be updating their driver soon?

Maybe reinstall the driver? Sorry, wish I were more help there.

I tried re-installing but did not work.  I tried using the using with another Win 7 machine I have, and the driver worked fine, so I think this is a Win 8 support issue...

Have you contacted their customer support?

I wonder how many DACs will have issues with Win 8? I was hoping compatibility would be high which would leave the door open for those new super-tablets like Surface, Acer W700, etc which have a real USB port.

Random observation just now: I have both the DAC-100 and HDP running side by side being fed identical streams (optical into HDP, and coax into DAC-100. With headphones plugged into each and sitting on my desk, I can tell there is a slight delay to the sound coming from the DAC-100.
 
When I did this with the DAC-100 vs the Bifrost, there was maybe a slight delay but less so than this, to the extent that I could not tell which was the delayed one, only that there was a slight time smear. I guess this makes the HDP "faster" for lack of a better word? Weird.

Hi Jason,
 
Please can you tell me about the USB adaptive mode which is concerned with the NuForce UDH-100. I ask as I use a mac with the Audirvana software which fully utilises its abilities when no drivers are required. I've noted that there is a mac driver download for the UDH-100. Can you confirm whether it is actually required given that from mid 2010 most macs can cope with 2.0 USB. I am hoping that I won't need to download it. A response from you would be most appreciated.
 
FYI - The U-DAC2se works fine with the software named above.

Yes, I have. They said they were aware of the issue with Windows 8, but did not tell me when they will have a Windows 8 compatible driver.

I got a UDH-100. its amazing. the volume pot is a tad bit flimsy or maybe its supposed to be that way (at first I thought it was broken) otherwise its superb just superb. truthfully I notice a rather big difference from my icon HDP even with my Schiit Valhalla plugged into the UDH-100 sounds better (so far I'm using the UDH-100's amp because they are actually driving my DT990's 600ohm better than the HDP did!) Shine on You Crazy Diamond 1-5 converted down from the SACD to 24/192 sounds AMAZING! 

 

[Armaegis]

Interesting. I wonder if it's the same amp section as the DAC-100 or the HAP-100, or something of its own (I think it's the DAC-100... but I'm not entirely certain). 

 

[Armaegis]

I've posted some comparisons of the DAC-100 vs the HDP here. http://www.head-fi.org/t/645068/review-nuforce-dac-100#post_9032836

so far the UDH-100 has been fantastic minus a driver issue. right now its RCA out is plugged into my HK 430 receiver and its the best ever sound I've heard coming from my 430. it's neat using my HK for a change because it makes my DT990's really move!

I don't know why this thread didn't come up when I did a search. Anyways, I got my DAC-100 today and I'm on my way to my new headphones cave to test it against the Lehmann Audio BCL as a headphones amp only. I'll post my unboxing video and impressions soon.

I wish I knew how strong the headphone output is on that thing.

Cool. Looking forward to it.

Is it my unit or the hissing noise is on the high side?  I am using a 32 Ohms headphone so maybe that's the problem.  I'll try a higher impedance headphone when I get back to my S.F. house.
