It's all relative, but I'm guessing you dont want to listen to Yggy if you have your heart set on Gungnir.

His words, not mine - dont shoot the messenger - but its interesting that the previous 'best I ever heard' gear suddenly sounds like crap when we get to hear a new toy
so I went back to the Gungnir and by comparison it sounded dry, brittle and 'digital'. Three words I never would have expected to use about the Gungnir.
I already have the Gungnir! I would love to make the move to the Yggy, if it was the right move. I am considering holding off until around July at the latest to see what may develop. Until then, I will have to read what others are experiencing with the Yggy. Cheers.
