I had a first generation Marantz CD63. Probably because I was using a 70s Technics amp and a pair of AR 3as, great bass but the rest was crap I wasn't impressed. Moved on to another Marantz the 63KI which I found sounded better than the much vaunted first gen.63 and I used it from 92 - 2016, only the on/off button packed up.
In 2022 I bought another Marantz the 6007. It sounds great and has an excellent h/amp. I have yet to try the digital section as I've had to wait to get my s/hand Puffin updated so that I can digitise my LPs.
I agree with the comments of so many, given decent design/materials used to construct the CDP, the sound of CD must come down to the DAC used and the quality of the CD itself. Some are really good. Via Intermezzo or maybe Stingray (I cannot rec. these 2 TV channels enough and it's not only music, seriously check them out, I get them for free via the French company Bouygues) Anyway I got to hear a Swedish Jazz trio - EST and bought 3 of their CDs, superb sound and wasn't aware that I was listening to CD. The Japanese also turn out very good sounding CDs. I'm not and never will be into streaming. Firstly it's an even worse rip-off for artists that record companies ever were. If they get together and act as one as those people who work in Hollywood did then streaming will become, as it should do very expensive and you get to own nothing. The cloud is a complete misnomer as the cloud is in fact big sheds built in the middle of nowhere consuming vast amounts of electricity and with little effort can be destroyed completely. Once one of these sheds is destroyed then teams of highly paid guards will be needed. Combine that with proper remuneration for the creators of content and it will become very expensive. I like to own my music and when I've digitised my physical media most has a high resale price.
