I loved the AMR cd77.1 when I owned a decade ago and have been trying to achieve that sound quality since.
That is a great CD player for sure, but digital marches on and DACs today are damn good. I’d encourage you to audition some of the newer R2R DACs from Denafrips Pontus ll, Musician Pegasus (that I own), Gustard R26, Mojo, Aqua, etc. And I’d absolutely upgrade the Node as, while not bad for the $$$, will be a big bottleneck to better streaming sound quality if/when you get a better DAC. Just my $0.02 FWIW, and best of luck.
