I agree Qobuz is best but Tidal works too if there is some reason you prefer it. I highly recommend the bluesound node to start. Great value at its price point. It's very easy to use- good interface and I found it to be very stable. While there will be a time to upgrade, I had one and thought the dac was fine. I think the biggest considerations as you start this journey are stability and ease of use. Bluesound will give you that and I think the sound quality is plenty good for the money.
Enjoy the music
