You have received good advice from duckworp and others. That is: you can't polish a turd. Life is too short for listening to compressed music.
Start by upgrading to at least redbook res. from Tidal etc. then upgrade streamer. I would suggest separate streamer and DAC. I have heard the Lumin which is impressive but streamers are emerging rapidly and having the 2 functions in one box is limiting. I am using a Wadia 15 (redbook only) DAC and doubt if I could find that perfromance from most combos except at insane prices.
