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!

I'd really recommend a California Audio Labs CL15. Mine was made in 1994, sounds great. I know they are a bit old, but....Cal Audio just got things right on the CD players.
They do come up for sale on Ebay and other sites typically <$1,000.
McIntosh MCD 205 or MCD 201. 
MCD 205 is a 5 CD changer with Nakamichi mechanism.
I really like the sound of mine. Very musical player! 
If you lucky enough you can find one in pristine condition for $1500 or so. 
Good luck!
thanks everyone, the search list on hifishark is getting pretty long...
Looks like a lightly used Cambridge CXC or Audiolab cdt6000 could fit well.How about the border patrol dac? Any experience?
Check out the Denon DCD-1600. Built like a tank, excellent DAC, about $1,200 with a 5yr warranty. I bought it because I wanted a really good 2-channel SACD player. It’s “Made in Japan” and it shows. 
SACDs sound sublime, but most of all I was surprised at the amount of additional detail the Denon pulls off Redbook CDs. 
FWIW, PS Audio decided to use the Denon transport in their new CD player...
+1 re the Denon DCD-1600NE.
My first SACD/CD player was a Marantz SA8004.  I replaced it with a Denon DCD-A100, which I bought gently used.  That was a big step up, but eventually I began to be tempted by the DCD-1600NE and the idea of buying it new so I could take it to a service center about an hour away, if I needed to.  Surprisingly, that was another step up.
As the previous poster said, the improvement in redbook CD's is especially notable.
