Looking for a CD player


Dear community,
I listen to CDs only and I have owned an entry level AMC CD9 CD player for the past 15 years.
Over time I modified this unit to the max with very good results.
Now I think I am ready to move on to the next level so I am looking for a used CD player under $1,500.
One that can be further improved would be also interesting.
Do you have any suggestions?
Thanks!

Hello,
All of this looks good. If you have a ok DAC you can sell it and buy the R2R Denifrips Arries.II. If you have a CD player with digital outs keep the player and spend it all on the DAC. The Denifrips Pontous. Slightly over budget but worth it. It’s all about the DAC. This DAC has twice the resisters and twice the power supply located under the DAC for better separation. Even if you had an older DVD or blueray player you will hear the results. Later you can upgrade your transport to a used Oppo, Cambridge cxc, or a jays. This is your best bet for the most impact and future proofing your system. You can also use the DAC for streaming in the future. I would recommend a BlueSound Node 2i. 
I hope this helps. I don’t know of a resellers for Denifrips. The BlueSound is at https://holmaudio.com/bluesound/
I know they were not expensive but the SONY ES models and Yamaha units have very good sound.  Using an optical cable is a must.
I was very happy with the Denon DCD-A100, and I have kept it as a backup.  The DCD-1600NE was clearer and more detailed.  Whenever I read those words, I wonder if someone is just talking about "brighter."  That's not it, in this case.  I think the DCD-1600NE simply does a better job of bringing out detail, and at no cost to the bottom end.  The two models use different DACs.

I have read that a new DCD-1600NE needs some time to burn in, and that has proven true in my case.  Several months after purchase, it still surprises me.
