Schiit DACs (Bifrost and Gungnir down, one to go)? The information and anticipation thread. - Page 177

post #2641 of 3320

I had the Audio-GD NFB-3 and the Schiit Bifrost. I liked the Bifrost better, but having opened them both up, I can tell the Bifrost could be even better with a power supply such as found in the Audio-GD. The Bifrost power supply is just your stock LM 337/317 regulators. While to be expected at this bargain price, it seems Schiit put the money into the quality output stage instead.

Two days ago the USB on my Bifrost stopped working. My laptop (running on Windows XP Pro) was not able to detect it anymore. I have tried reinstalling the USB driver. Even though I have already plug in the USB cable but the installer kept on asking me to plug in the device/Bifrost. At first I thought it could be the AudioQuest Forest USB cable. So I tried with another USB cable. Still the same issue. Then I tried with my other two laptops (Vista Business and Windows 7 Pro). Still the same issue. Does anyone face similar issue before?

First I've heard of anyone having this issue. Since you've tried it on different computers and different cables it does sound like something's wrong with the Bifrost. If you're comfortable doing so, you may want to open up the Bifrost and see if the USB card might have come loose (due to the modular design).

Irs just a few screws I would definately check it out.  I don't know if the USB card has an LED on it because mines is USB-Free at the moment but alot of USB chips have a diagnostics LED.

 

Otherwise its the USB card that went bad.  I would also be careful with expensive USB cables~  they make alot of claims and while I don't think an improperly wired usb cable would work(Not an expert, can't claim to understand its inner workings) even low voltages if improperly routed can burn out a chip. If not right away, over time.  Generally with digital components though it happens right away given how sensitive they are.  I single out expensive cables because they are made to be "different" from standard usb cables.

Jason replied immediately (good customer service) to my email. He gave me another USB driver to install. However, the USB driver does not fix the issue. I am getting my company system administrator to take a look at this issue (checking the Windows and reinstall the old and new USB drivers). My company administrator also has a Mac which we will use it to test it.

Thanks for the advice. Opening up Bifrost will be last option. However, I will ask Jason first before I open up Bifrost. I have already single out the usb cable.

I'm very interested in hearing how the Bifrost will compare to the DAC HD cable by Halide Design, seeing as they're in the same price range and ones a little more "simple" than the other.

Well... my Bifrost is on the way back to Schiit office. Been using the E17 as the DAC since few days back and it felt like downgrading. I mean, still listenable but the some of the listening pleasure is gone.

i am looking to upgrade from the audinst dac.

 

so far i have narrowed it down to:

audio-gd nfb 3.1

schiit bifrost

grant fidelity tubedac-11

 

all are in the same price range

 

my headphone amp is matrix m-stage and i will be using the audio-gd DI for a coax interface

 

im leaning towards the schiit bifrost but the feedback on the nfb 3.1 is making me reconsider.  which would you guys get?

post #2650 of 3320

I think most people in this thread have the bifrost or favor it.  Probably not the best place to ask :)

post #2651 of 3320

I certainly favor it!

 

In other news, we're looking for input on SACD and DSD--your chance to win a Bifrost:

Don't know about NFB-3.1, but i do own NFB-3. Bifrost is better in my opinion. In comparision NFB-3 is just a little too smooth, not as transparent as Bifrost.

So, I'm not sure what happened, but now my computer isn't playing back via digital coax.  When I first installed the drivers and got everything setup, it worked fine, as did the USB input.  Now, when I choose the SPDIF input in JRiver Media Jukebox (or iTunes) and on the Bifrost selector, I'm getting nothing.  Dead silence.

 

Do I need to uninstall/re-install the drivers?  USB works fine, but would like to switch between the two for AB comparisons.

 

Any ideas?

 

Thanks!

The first post is finally back up to date guys. Sorry for anyone that felt neglected during the past month - life has been busy!

The Bifrost is an exceptional piece of audio hardware. As an EE, I really appreciate the performance and quality of the Bifrost. It actually amazes me that Schiit can do this at such a low price point. It took around 200 hours of break-in for the sonics to smooth out in the highs. My only gripe is that the LEDs are too bright. A different resistor value would fix this. I am also impressed with Jason's fast email response and excellent customer service.
