Since you already have an amplifier and good speakers, then yes ... add a CD player. The amount of money you want to drop on that purchase will be dictated by an honest appraisal of yourself as to whether you think you can distinguish a difference in sound and/or how much you will be popping CDs in reality. Also consider how you listen to the music - is it on in the background or will you be sitting, actively listening.
I ripped all my CDs decades ago (well, two ... when I got my 'Rip Mix Burn' iMac) and re-ripped within the last decade to Apple Lossless. I'm happy enough with that musical library in digital format, streamed from my (aged) Mac via an Airport Express (AirTunes) to my amplifier. That setup satisfies me for my desire to actively listen to the music without wanting to get back to the original CDs. That said, I have considered a CD player again in the last few years ... but it passed.
If music is to be on in the house as background, I do like the configurability of smart speakers. I have Apple HomePod Minis, one upstairs and one downstairs. I can stream to one, the other or both from my Mac controlled from my phone with Shared Library & iTunes Remote. For a speaker unit that is little larger than a softball, they do a perfectly good job for just playing music.
I do have a record player with about 8-10' of 12" & LPs and a short box of 7". I do listen (actively) to the vinyl, usually through (wired) headphones. Being a collector of specific bands, I have multiple versions of a lot of their releases ... and re-bought many albums maybe 5-6 years ago on 180gram vinyl after buying a new set of headphones and setting my HiFi back up ... without CD player, tuner, DAT, cassette, etc seperates. Just amplifier and record player.
In the next decade I'm likely to buy a new amplifier and record player of a better audiophile quality, not that my kit is at all highbrow, but there's a future in my vinyl ... and everything else, I'm happy enough to have electronically just to play. I guess I could actually ditch the CD collection now it's ripped in a format that is unlikely to be surpassed. That said, most CDs form part of a collection of specific bands.
... so it comes back to whether it's likely to be a fad, whether you think you'll be able to hear a difference and how you'll be listening to your CDs. To be frank, regardless, you can pick up a known brand name CD seperate for near nowt second-hand nowadays. Cash Converters, CEX, etc.
