Why does my old CD player sound so much better than my new streamer?


Earlier this year I upgraded my system. Briefly, new Prima Luna Dialogue Premium HP integrated, new Lumin D2 streamer/DAC, kept my Tekton speakers, bought a 10 year old Muse Erato CD player, new Nordost Red Dawn cables all around.  After plenty of break in, the Lumin D2 streaming Tidal, even 24/96, does not sound close to as good as the Muse Erato.  I understand the Muse was about $10k new years ago, I paid $650 for it on Audiogon, is that the difference? It replaced my Naim I had for 20+ years and I bought it on the chance I want to listen to something not on Tidal, but now I'm going to CDs when I want to sit and listen instead of streaming. I considered upgrading to the Lumin T2, but will that be more of the same Lumin sound, which is accurate but thin and a little cold compared to the Muse.  I like the Lumin when just letting Tidal shuffle music as I move around the house, but from the opening note in an A/B test the Muse just sounds so much warmer, live and simply more enjoyable. Any thoughts or suggestions?

"...changing to one of the new AQ power cables and a set of Isoacoustics footers." LOL!!!
Thank you for the comments.  To Audiotroy, I just did a plug n play with the Lumin, did not play with a set up menu nor do I know how. Is it in the Lumin app? I am using Wi-Fi, cannot direct connect with Ethernet. I am using the stock power cable.  I am running Roon but when I first set it up was using the Lumin app and set the volume all the way up but found it less harsh with the Lumin volume set to 3/4, but this was before burn in. I can go back and turn it up all the way.
How are you actually retrieving the music?  Are you using a streaming service or retrieving files from some storage device?  Did you rip your CDs, and if so, have you compared the rip to playback from your CD player?  I ask because I've heard plenty of crap sounding albums from streaming services, even those claiming CD quality.  

Everything counts in audio.  How everything is connected up matters.  I don't use WiFi for anything audio (except to control devices via a iPad), so I don't know if it degrades the sound, but, that certainly is a possibility.  One of the dealers in my area, hates USB connection, another thinks that having really high quality ethernet connections count a lot.
