Soulnote D1 v2 DAC upgrade.... compared to Holo Audio Spring 2 Kitsune

Hello fellow obsessives, 

I am thinking of taking the plunge in the Soulnote D1 dac. It's qualities I hope will tip my system toward the exuberance I yearn for... the energy and the openness... currently its sublime but somewhat... subdued... exalted and gorgeous, but somehow lacking the energy I desire....

What do you all think of the Soulnote D1 DAC, as an upgrade from a Holo Audio Spring 2 ladder R2R? 

And... should I keep my Holo Audio DAC for my second system (currently served by a Musical Paradise DAC)? Or should I actually learn to let go of these things and sell it to a online store for 1K?

thanks for all advice,

R.
