Depending on how much you want to invest, it could be a huge leap in improvement. I went from a whole Bluesound house to in the end having one with a power supply upgrade, moving to a NAD M50.2 streamer which is now discontinued, but was leaps ahead. I’ve tried a number of better streamers, from Innuos, Laufer Teknik, Auralic, and Aurender (in full disclosure I am an authorized dealer for Aurender) as well as many home-baked PC servers.
While the modded node is very good for its price, the power supply upgrade is just piece, and overall the Node is not protecting itself from any noise. Once you upgrade to a streamer that cares deeply about isolation, clocking, caching and all, you will realize how much more clarity and information you get with less fatigue.
