Ohhhh, I found that bass!
OK, so I was wrong... The Yggy does wanna do battle after all
Turns out the secret ingredient I was missing was the Stillpoints Ultra Mini footers I had placed under the Eximus DP1.
Apparently placing them under the Yggdrasil has the same effect of fattening up the lower-mid and bass regions.
Dare I say it sounds even more similar to the DP1 now... EXCEPT... the Yggy is still more coherent.
There's something kind of fun about the way this DAC sounds, I'm definitely digging what I hear so far.
The fact that it sounds every bit as good or better than the DP1 straight out of the box is pretty impressive.
