Why Purchase A CD Player or Transport ?

@cey +1: it is a joy to have a nice collection of LPs and CDs and being able to select at leisure something to listen to! Streaming is to music as is reading a book on  a screen! I'd rather hold and read a physical book.

that is a great analogy.  I actively dislike reading on a tablet

I must agree with you. I am interviewing Amps and Receivers currently and when you walk into a store and they can't play something that you know well...

I have always taken in my own music and now all they want to do is stream and they can't do that correctly. One store actually didn't know how to change sources. I wanted to be listening to something from Steinway & Bros. studio recordings and I was hearing VOCALS. This was the Oldest and best So-CAlled Hi-End store in Denver. Another had the ability to play disks if you consider an Xbox a suitable transport device. I am thinking if I want to look for new equipment I will have to drive or fly to Albuquerque or Salt Lake City because Denver HAS NOTHING to offer. Of course, this hilly billy town never did have any class.
But back to your comment. I know of a lot of offerings that are not readily available. Possibly they will have one from the same musician but not the album you want to hear. That is unless you want to listen to Youtube. Then there are issues with the providers. Amazon music likes playing the ignorant game of not providing consistent service if you use something other than Firefox for a web browser. If places like that can't grow up...

Then there are the bit rates of the different services. I believe that 16/48 should be a minimum even for the free users and then when looking at what is offered, not everything is offered at higher quality bitrates. I know this is improving but still lacks hugely.

I took these past few 'stay at home' years to upgrade, bit by bit, until main/office/garage-shop systems were all upgraded.

Began with wanting a long tonearm. Led to a TT with 3 tonearms, proper mono listening for the first time, and essentially all vinyl.

However, I own a heck of a lot of CDs and SACDs, and I started a quest for a better sounding SACD/CD player.

I went thru 9 different players until I settled on my Sony xa5400es

I went thru a re-discovery process, opposite of vinyl re-discovery, it put new life in all my existing CDs and I am buying used CDs occassionally without hesitation. after R2R tape, vinyl is preferred, but my CDs sound better than ever!

Do It.

@vonhelmholtz Why not invest in a proper high resolution file server instead? Do you already have the CDs that you want to be playing through a transport? If not, you will still have to find and buy them. Most high resolution albums, even DSD versions from a SACD are available for purchase for download to local storage from HDTracks, 7digital, or other services. A proper high resolution server will have no spinning parts, hence less vibration, with lower noise through a quality internal LPS, SSD storage and file caching, and improved isolation from non-digital signals. You will get a bit further with your money this route, as chances are you would invest in a file server down the road anyways once buying, storing, and playing discs becomes too cumbersome.

The NUC you have is a great start but there are much better server solutions that include the features I list above, and the sound quality will be a huge step forward with them as a result. Happy to chat options with you over PM.
