You mention your source for your DAC is a Bluesound Node 2i. I’m curious if you’ve tried a better streamer. While there is a wide variety of opinions on the importance of source, in my own experience, I enjoyed a bigger performance gain by improving my source than I did by moving to a better DAC. While my own DAC isn’t as well regarded as yours, it’s still very good. I’ve auditioned some that were in the price range of yours but didn’t feel it enough of an improvement over what I have to merit the spend.
I should note that there are some here who say source makes little to no difference (either out of belief, but some from experience) and/or that their DAC is immune to jitter. Regardless, some of of us have experienced significant improvements with a better source. FYI - I started with a Node 2. It was very good for what it is, but I wouldn’t go back. Of course, YMMV and perhaps you’ve already explored this, but I’d be curious as to your experience.
Best,
