@labguy,
As many of us suggested above, buy the Blusound Node 2i which comes with at least 15-30 days return policy from quite a few online retailers. Once you have node 2i in-house, do an A/B comparison with Node 2i internal DAC vs. ZDac. Also sign up for free trial with Tidal to compare SQ with Spotify. Many finds Spotify SQ acceptable but without a doubt Tidal and Qobuz offers much better streaming sound quality.
In the end, Trust your ears and make an informed decision.
