HAP-100 review to add to the DAC-100 impressions here - I was 90% done 4 months ago, so sorry it took so long.

I will hopefully get my HAP-100 impressions up soon as well. I did recently add a couple notes to my DAC-100 review though. I noted that the sound is better from the coax/optical inputs vs the usb, and that the DAC-100 is not compatible with ipad but the LPS is, which tells me there's some difference in how their usb is implemented (although the boards look practically identical in each, so appearances are deceiving).

I've been using the Nuforce iDo for the iPad and sending it's coax out into the DAC-100 with it, so I hadn't bothered to try the iPad with CCK into the DAC-100.  I do think the USB via Macbook is very close to the optical input from Macbook, but hadn't really given much thought to just how different they are.  The DAC-100 USB input is definitely better than the USB input on my $900 Stello DA100 Signature.

Interesting, I couldn't tell any differences between USB and SPDIF on mine. I figured it all gets processed the same way and ends up sounding identical (plus NuForce told me it measures the same). 

 

Finally got the HAP-100 in and it has a completely silent background! For that reason alone it is probably worth the premium over just the DAC-100. Need to play with it more though.

Strange. Over in my review thread someone just said that the iPad4 works with their DAC-100, so I wonder why it didn't work with mine.

I was really expecting it to be the same as well. Heck, considering how similar the usb boards were I was suspecting that it did the exact same function and converted internally to spdif. Maybe not though. 

 

Or maybe my unit is an oddball since the board apparently behaves differently since it wasn't compatible with the iPad4.

Arrrrgh! I wish they would update that driver. I just hate how it randomly screws up my PC. I will have to uninstall the driver because windows will no longer recognize the UDH-100 for no reason and if I go into sound settings in control panel Windows Explorer will crash and I need to force close it.

I get a pretty bad crash if I accidentally bump the usb cord while music is playing. It won't even shut down after that; I have to do a hard rest of the laptop to reboot. I don't think this is specifically driver related though.

that's never happened to me. hmmm... strange. when mine decides to act up it will take forever to shut down and when it reboots it will hang on the Asus logo until you hold the off button for 10 seconds. I've been messaging them on facebook about it and they are very nice about it. this really is a great DAC though so it's worth it. I know this is a DAC-100 thread but there's nothing on the UDH-100 and they are pretty much the same minus the extra inputs. 

post #219 of 292

I don't know... I was surprised that I heard a difference between the usb and coax inputs on my DAC-100. Project86 didn't hear it, but it seemed quite clear to me, and I found the coax better.

I currently have the UDH-100 here for review and i can't get USB to work. The DAC isnt recognized at all when plugging it in. I run Windows 8 64bit, tried all USB ports. Many other devices run perfectly fine. Doesn't matter if it's plugged in before or after Driver install. No new hardware get's detected.

 

I tried it on another PC and there it get's recognized without Problems when plugging it in, so atleast it's not the USB cable.

 

Any ideas what i can do in this case?

Not sure. There seems to be a good number of USB problems these days, what with Windows 8 and Windows 7 coexisting at the moment, both in 32 and 64-bit varieties. Some of us (like me, fortunately) have very few problems but apparently that's just luck of the draw. 

 

I'd say if you get the UDH-100 working on another machine, then clearly it has something to do with your main PC. You aren't using a USB 3.0 port by any chance?

post #222 of 292

Nope don't have any USB 3.0 ports in my machine. I just tried by adding a NEC USB PCI card i still had lying around and that didn't help either. Windows Devicemanager says "No Drivers installed for this device". confused.gif

 

Never had such problems with the asus xonar essence one.

 

 

EDIT: Manually choosing the driver seems to work, however i get a lot of stuttering. Atleast i'm a step loser.

 

EDIT 2: Everything works fine now. :)

 

EDIT 3: This was my Post #1000! Dedicated to nuforce :) It's a great sounding unit by the way.

What did you do to fix it?

I had to manually update the driver. First you need to install the driver, then connect the DAC/UDH-100. If nothing happens as it did on my system, go to the device manager and click on the nuforce device entry. Click on update driver and choose to get a list of installed drivers, then choose "USB HD Stereo Audio Device". There is also an entry for the async usb variant of the same driver but i got stuttering with that one.

post #225 of 292

Couldn't find "USB HD Stereo Audio Device" on the installed drivers list!!

 

DAC 100 not working on Windows 8!

 

Help please confused.gif
