Schiit DAC Crashes Audirvana

Schiit has always been prompt with inquiries, for me. 
I would try to call them directly, if possible.
Please don't give up on them. They are a stand up company and will do right by you.

After two days finally got Schiit support to respond. Solution was simple, to restrict output from Audirvana to 24 bit. Something you'd think Schiit might have mentioned in their instructions.

So far a frustrating experience dealing with Schiit, I hope  now that I have the DAC working my impressions change.

@cdc2 - I am so glad a solution was forthcoming. Now you will be able to enjoy extraordinary sound quality from the gungnir.

Having said that - IF you are using the Gungnir's  USB interface I would recommend you at least employ the following in order to maximize SQ

The dual cables provides more complete signal transfer because the signal line is separate and the power supply provides a more stable voltage fpr the DAC's USB interface to work with.

One problem in using the 5V supply on the computer is that it becomes less stable each the computers hard drive is accessed - not to mention all of the other circuitry inside.

There are other similar cables & adapters on the market, but these two provide excellent improvements in sound quality for a reasonable outlay

I tried several different cables and I think the Doukmall cable provided the best sound. I've also tried different power supplies and found the Enercell to be just as effective as a good batter power supply.

To improve my sound quality even further I invested in a V-link192 USB-SPDIF converter - it proved to be the icing on the cake

There are many more similar USB devices designed to improve the performance of  your computers USB port, but the cost rises as their technology gets more complex.

Personally, I finally decided that using Ethernet was a better solution for accessing music files on my NAS drive - so I opted to replace the v-link192 & Bifrost with a Bluesound Node-2
- life has actually got a lot simpler now the computer has been removed from the mix.
- the sound quality of the Node-2's on-board DAC and associated analogue output stage also improved - beyond my expectations
- The V-link192 and Bifrost are no longer in my system

Hope this helps

I'm glad Schiit finally got back to you.  I've got the Bifrost Multibit, and it makes crappy mp3 files sound better than I've ever heard them.  I expect the Gumby (Schiit gearhead lingo for Gungnir Multibit) would sound even better at 18 bits.
