I think my homework assignment was to listen to my (new-to-me) HD800 balanced from the Liquid Carbon, while fed sound from a few different DACs and DAPs. Unfortunately my DAPs both decided to take a vacation, so I'm only now getting back to the thread. In my preferred order from least-liked to most-liked:
- Chord Mojo - this DAC seemed to have the poorest balance from its lowest to its highest frequency. It seems a little forward on the high, which is an attribute I appreciated with my HD650 headphones. It was the only setup that made the HD800 seem a little bright, through the Liquid Carbon. There's lots of detail, which I love when it is executed correctly. The Mojo does this! It only loses to the other two options in terms of frequency balance. I'll need to listen to the naked Mojo into HD800 at some point.
- Pono - this only beats out the Mojo due to a better low to high frequency balance. Details are definitely dialed back - this is the least detailed of the three options. And, at the same time as I would claim the details are a little less, the details that come through are slightly more etched. Sometimes when reading a review, one might conclude that there are dramatic differences between products. That is not the case - only in direct comparison would I use the words dialed back and etched to describe the sound. The sound is really quite good enough to be end-game. I could easily listen to this for hours!
- Schiit Gungnir Multibit (balanced) - there's more meat to the sound. The sound is balanced from the highs to the lows. Perhaps there is less detail than the Mojo, but I find the Mojo's concept of details to often be false - perhaps a little more processed into existence than really there in the recording. Again, don't read too much into this - I like the Mojo. And it might be more interesting to compare the level of detail between the Mojo and my Yggdrasil, to see if perhaps the Gungnir is actually just a little dialed back.
TL;DR - Mojo has the most detail, but seems a little hot on the treble. Pono beats it (to my ears) by being more balanced, and is good enough for end-game into the Liquid Carbon. Gumby adds more depth to the individual sounds, and is my end-game (for today) with my non-planar headphones (i.e. HD800).
