I have a question for people with technical background: I haven't any even if I appreciate numbers.
I own a Node 2i and I use it as a plain music streamer (Tidal HiFi subscription) as it is connected to my beloved Matrix Audio X-Sabre Pro Mqa via a Coax connection (then connected via Xlr cables to a McIntosh MA7900 and then to Martin Logan Ethos electrostatic speakers).
If I use a better quality streamer like, as an example, a Lumin U1 Mini do I get a better quality in sound or it's just the Dac that can improve quality?
Or, another example, a Matrix Element X can give a better sound quality with respect to my Node 2i + Matrix X-Sabre Pro Mqa?
