Thanks for the impressions. I have the Holo spring 2 Wild and I agree.. I'm also using it with i2s. The imaging is not as pinpoint and placement is not as distinct, and the soundstage is not as wide, when compared to my matrix audio xsabre pro. It is, however, a very relaxed and natural sounding dac. Xsabre seems more detailed and neutral to me, more similar to dac3b.
Don't get me wrong, the Spring 2 and the Yggy are still great DACs considering they are what, almost 1/3 the price of the base Rockna ? Luckily for me got a great deal on a used model.
You'll get that natural, organic sound out of the Rockna, just without it being smoothed over. It's that liquid, detailed sound. Yet it's for transients for days. On top of that you'll find most Rockna owners agree dense imaging, and spacing are strong suits.
The Rockna designer has got tons of experience in this space and it really shows with his products
