I use the Node 1 and output to my DAC. So using the Bluesound App, I will connect to Tidal and use Tidal's MQA unfolding (which isn't a complete unfolding). The Bluesound does no MQA unfolding itself.
The alternative is to get a DAC with MQA capability, but, for me, I don't find the upgrade in sound reproduction to be worth it. In fact, I find Spotify (Premium) to be more than enough for my needs.
If I want to pursue higher fidelity, I would play my CD's. But, I have to say, I haven't played any for almost a year. I find the convenience and the completeness of the Spotify catalog outweighs any fidelity shortcomings.- And, in probably a couple of years, sound reproduction will have improved even more.
If you want to ditch the PC, then get a Bluesound Vault for streaming local music. In fact, I may be going that direction, too.
