Lol, I will say to date the M2 and ETHER is the best setup I have heard. Will likely be my end game setup.
JRiver>Wyrd>Modi2Uber>Mojilnir 2>ETHER
using pyst usb cables from PC to Wyrd and Wyrd to Modi and blue jeans rca cables from Modi2U to Mojilnir 2.
The only thing that may change will be adding a Gungnir MB. I'm not certain how much improvement I would notice going from Modi2U to Gungnir MB.
I would like to hear from anyone who has both feeding a M2 to determine if the diminishing returns is worthwhile. The stackability will be a big plus. The Wyrd/Modi stack is stacked upon the M2's front left corner, not exactly aesthetically pleasing.
Quite a bit of improved SQ by going to the GMB, IMO. And, as detailed by MattTCG above.
My progression was UberBi - Gungnir - GMB. Every step was an improvement.
