Converting cd's to high resolution audio

I am also in the market for a CD ripper. There is the Cocktail Audio X40 streamer/cd ripper/ cd player (and X30 that includes an amp) that interests me, but very few reviews out there. Compared to the other rippers on the market, this one uses a ESS Sabre DAC, one of the better DACs in the market. 

If you have an Oppo or similar player a simple method is to rip the CDs to a portable hard disk using a program like "Exact Audio Copy.". They can easily be played them through an Oppo via USB directly and controlled from your phone.

Or you can use a lap-top to play them through any DAC that has a USB input. If it doesn’t have USB you can use a USB to spdif converter. If you use a program like JRiver you can rip them even more conveniently and also control from your phone.

OP
first of all, very few CDs “degrade”.  I still have mine from the early 80s and they play just fine.
  I have ripped several hundred CDs to the Vault2 and to a hard drive.  Nothing has broke.
I think that you have read too much Audiophile nonsense.  

I also own CDs I use from the very first days of CD!
I have never seen a CD degrade! (though I have seen CDs at the library where the data side surface peels off, but of hundreds of thousands rare. way below like 0,001%

Well sorry to tell you there is.
The main reason I bought a new Marantz SACD/CD player with digital inputs was the fact it really does do more with CD than I ever heard before.
The Marantz DAC secion converts the CD data to DSD and then ups the game to Mhz territory to decode.
The results are CD sound as good as any SACD, and better since so many SACD destroy the room, presenting as if out of a black hole. (not so when it does CDs. more detail and the room is still there. lust better.
I had looked a long time for something to be a lot better than my old $250 used DAC! (in this quest I tried a raved about $2500 DAC and found it was no better than my used Adcom, and I returned it) I am cheap, but the Marantz was worth the $7K
It finally made my digital sound as good (but different) than my turntable

I concur w/ Elizabeth, in that, there is an incredible amount of information stored/locked onto a CD or SACD. Historically, there have been a few players that possessed an ability to unlock ,  retrieve, the data in those pits and lands. The new Marantz SA-10 is such a player and relative bargain compared to the top-tier Esoteric (both actual brand) and other  spinners in the $15K to 50K neighborhood. 

Secondly, the DAC has come of age and properly matched w/ the best transport (C.E.C and other brands) offers the listener a never before musical experience.
Happy Listening!
