Upgrade from Schiit Bifrost 2?

I assume you had a bad experience with your Bifrost. Typically I always invest at least two to three times in a component, it will get you a “Wow” in improved SQ. In the price category you appear to be in, my recommendation would be the Gungnir multi-bit or if you are planning on upgrading your system over time the Yggdrasil. I have done a lot of research (purchasing a Gungnir multibit, and a Yggi for a friend) and in these price categories: $1,300 and $2,500 they are outstanding bargains. You will get overall improvement in sound quality with more natural sound. 

Probably not what you want to hear. But unless, you are willing to jump into the $5K range these are probably the most cost effective choices.

Thanks. I'm looking for non-Schiit recommendations. Thank you.

If you don’t mind me asking, do you know what damage your Bifrost? It seems rare to hear about DACs failing, but then again of course anything can happen with electronics.

It stopped producing sound and I noticed that it was warmed than I remember, even though it was sitting on top of the cabinet with plenty of air flow. I unplugged the Bifrost 2 and let it cool down for a while and when I plugged it in, it didn't power up.

Sorry to hear that about the Bifrost.  It is a good DAC.  I did upgrade to an Audiomirror Tubador SE and a Bricasti M3.  Both are considerably more expensive, but they are both a bit more neutral signature than the Bifrost - Schiit seems to like a bit of warm emphasis on their DACs with some bass slam.  See the reviews by Goldensound on YouTube - he seems to have good ears backed by measurements.  The Audiomirror is available in a non-SE version that will give most of the benefits for $1500 rather than $2500 so it might be a good upgrade option.
