Is it worth upgrading a CD player?

I is amazing to me how popular streaming is today. I have a very simple 2 source system. I have a Rega elex-r integrated all analog amp. I have a P3 modified with all 3 groovetracer upgrades and a Rega exact 2 mm cart. My other source is a 2017 Rega Apollo used as transport and connected by Kimber $390 rca digital cable to a Rega dac r(last dac they produced, I believe they ended production in 2015? I have all Kimber cable for different needs. I get so much enjoyment from this system I am done. My loudspeakers are Meadowlark audio swift floorstanders. They have vifa drivers. 1” silk dome tweeter and 5 1/4 woofer. They are a true transmission line design. I have had them since 2002. They are immaculate and musically very satisfying. Glad that is out of the way. Ok. I cannot understand how so many people are throwing money away on a predominantly streaming based system. I would love to have access to Tidal and Quobuz, but the majority of posts I read suggest today they are spending at or over $10,000 on their streamer, their dac and linear power supplies, etc. They are throwing their money into a bottomless pit. And setting up a streaming system has so many hardware and software issues to contend with. And most listen to red book cd quality as the predominant format. I can understand wanting to try out MQA or DSD, but they are listening to some average sounding formats and I guarantee you that my humble $1700 digital front end sounds as good or better than their streamer. Am I missing something. I am a little new to streaming but I have been into this hobby for over 30 years. I like Aurender a lot. I would never invest in such a high cost fad. And I have not even gotten into all of the software issues when pairing this gear. Maybe I am missing something? Someone have another way of looking at this way too complicated and expensive fad. Thanks.
