Gungnir sound before and after multi-bit upgrade?

Would appreciate reading owners' descriptions of what they heard before and after upgrading their Schiit DACs to multi-bit.  What were the sonic benefits?  Mostly interested in effects on the Gungnir but would be interested in comments about Modi, BiFrost or Yggdrasil as well.  

Searched here on A'gon but did not come across anything that clearly addressed before and after sound.  

If this has been discussed and I missed it, my apologies but please link me to it.   

Thanks in advance.
