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

Honestly, my view is that the CD transport (as long as it mechanically and optically works) doesn't matter that much. The DAC is key - you can find yourself an old CD player, or newer at a reasonable price to match your budget. Typically the DAC's in the older transports are terrible. Instead hook it up via optical to your DAC (if you have one) and it'll sound amazing. I have an old 50+ cd carousel that I've had since college and paired with my DAC sounds epic. 

Many go on the hunt at the local thrift store if that is your thing, find a decent one and hook it up to a good DAC. 

Just my 2c. I wouldn't spend that much on a CD player (unless you really want SACD) - and instead splurge the rest on a DAC or simply connect it to your DAC.

This is not my experience at all. Switching from a Moon 260 DT to a Jay’s CDT2MK3 resulted in a very noticeable improvement. I’m confident many others here will agree that the transport can make a significant difference. 

@stuartk Fair, perhaps a gross simplification on my part. Reading up on the Jay's CD transport I can see how much of their tech would help there. 

I guess depends on appetite for budget - but I also still think pairing a CD player with a good DAC will make a huge difference. Thanks for correction. :) 

@rikkipuu Yes, that is what I am starting to find out too. It will cost me a lot of money to get a transport at the same level. 

Personally, I ripped all my CD's to a server after my transport died and the CD's are now out of the way in storage.   Very high WAF.

I've optimized streaming with switches, filters, optical and the like to where Qobuz sounds amazing and more often better than the same file from the Innuos server, and that holds true for Hi-Rez music I purchased and downloaded.  I do feel DSD sounds better in general, too bad it can't be streamed by Qobuz.

Even if you keep your CD's they have a lifespan.  Most will be good for 100 years but 4 percent reach end of life at 10 years.  Temperature and humidity play a huge role, a disc's life span can be increased over 10 fold by storing at 50 degrees and 35 % humidity vs 77 degrees and 50 % humidity.

I suspect my response as worded comes across with an "edge" I wasn't originally  cognizant of. My apologies.  If memory serves, I paid 2k for the Moon and 2.5k for the Jay's. The latter just seems to extract more sonic information from the disc. I'm not technically astute, so this may not be what actually occurs. It's simply the best verbal description I can formulate for what I've heard.
