My CD-player stopped working. Does it make sense to invest in a new CD-transport?

If I were in your position, I would get a quality CDT. A few reasons why. I enjoy listening to vinyl, CDs, and streaming. But, I have quite a few recordings that aren't available on streaming platforms and may not ever be. I might be able to find a poor-quality ripped version on Spotify and Quboz isn't as comprehensive in some musical genres or an artist's catalog as I would like. That being said. I still buy CDs because I enjoy the ritual, the liner notes, and it's cheaper to find a solid recording I want on CD for less than a crappy copy on vinyl. Another reason for a CDT or home streaming server, is that streaming services can go down, lose licensing rights to artists, or have incomplete albums, etc.  Sometimes, the original release of a recording gets nixed in favor of the "re-mastered" version and isn't available anymore. I also find that when listening to CDs or vinyl, I'm committing to listening to an entire album. Less so with streaming. But that's me.

The final reason I continue to enjoy physical formats is that I can choose to sever the digital cord whenever I want and not lose my collection. 

Seems an obvious answer that being do you listen to your CDs. Buy another player or toss your CDs (to me). Opinions are not facts so don’t waste your time. That said recording practises very so to the end result ! I bought a new Teac Pd-H600 player which I use occasionally for my collection of Flack downloaded or bought. IMO this was Teac’s best offering incredibly well built, no bells and whistles. If you can find one, it blows many higher end offerings out of the water. 
Ps; My opinions 😁

Cheers

Being guided by what you hear is limited by what components and masters you have heard. Which is why one would ask questions of folks that have lots of experience across components, masters, media,  in different systems to understand the underlying realities. 

Just to be clear, I wasn’t in any way suggesting the OP ignore "underlying realities" to which we’re all subject. Furthermore, I have the utmost respect for you; I would never suggest anyone ignore your contributions or those of any other seasoned audiophiles. 

My post was in response to my impression, which may be erroneous, that the OP is not "owning" the decision making process; he seems to be asking us to convince him to go one way or another without much introspection on his part.

In the end, it’s his ears he has to please in his room, with his budget, ancillary gear, etc. If he’s not paying close attention to what he finds pleasing, I’m not convinced he can actually achieve a desirable outcome. 

But, as I said, I may be drawing erroneous conclusions. 

I spin t table,cd and stream.its all good and there are still companies making cd player. Read the reviews find one that will last another decade and perhaps buy a spare laser. Teac vrds 701 has been around forever.enjoy it all.

Stievus,

All streaming is compressed.  It has to be to go through the Internet.

That means you are losing the highs and lows to some degree.  That doesn't mean streaming sounds bad but CD's do have a wider dynamic range by definition.  

To get the most out of a cd transport you do want an I2S connection but then your dac needs an I2S connection also.  The cost is always a problem.  To get the I2S connections the price goes up.  I use all PS Audio equipment.  There new transport and dac cost $9,000 each.  I know that price is high for most people.  The alternative is to buy the PS Audio previous generation which lots of people are trading in for the new gen.  I used the previous generation for years and it sounded amazing.  Buy once and cry once but enjoy the benefits for years.  Save your money till you can get a good transport and dac with the I2S connections.  You will enjoy a new level of music if that's what you want.
