In a good system Digital Playback is a Poster child for the old Linn proverb: “Garbage in, Garbage out”.
A good system will provide an un-merciful rendition of a poorly handled digital source, the better the system the more agonizing the rendition.
Source matters most, everything that follows just tries to not harm that signal - which is why you use tubes and Class A.
Get the best streamer you can, spend the most on it followed by the pre-amp then DAC, then on whatever but keep in mind that noise is the gremlin of digital and you will need filters on your Ethernet and maybe other cables and at least one high end switch with a high end clock or outboard clock. Power conditioners and grounding boxes and the quality of power cords have a great influence on the noise.
I recently upgraded my Innuos Statement to Next Gen. Essentially only the dedicated power supply was upgraded and the improvement is astounding in terms of background quietness, detail and air. The fullness and decay of the notes is amazing. The upgrade was all about noise control, it was expensive but for me brought my system to a new level and has pretty much killed the upgrade bug- well except I am maybe looking at a Network Acoustics Muon USB cable.
FWIW Qobuz sounds worlds better than Tidal and there are control/playback apps that sound way better than Roon and they are without subscription fees.
