My experience on DAC choice: I bought a McIntosh D150 one year ago. I have done countless comparisons Bluesound Node 2 + D150 + Amplifier vs Node 2 + Amplifier. I am not able to hear any difference. For my ears, with my speakers and amplifier, thje Node 2 DAC is as good as the D150.
So my advice is: compare the two DAC (old and new) on your system before buying it.
