Recommendations for used CD player


I'm looking to improve my sound by adding a CD player to my system.  I'm currently now just using a Yamaha DVD player along with a Yamaha Aventage home theater receiver (which uses ESS Technology ES9006 SABRE DACs).  I use the receiver as a pre/pro with a Threshold S500/II amp and B&W 802 Series 2 speakers.

Right now I really like my sound and I've read these DACs are fairly high quality, but wasn't sure if I could get improved sound by adding a used, higher end CD player and possibly outboard DAC.

No SACD needed, my budget is about $400-500.

Thanks.

I once owned the DL III. Good DAC for the money. However the USB input was not asynchronous. I used it with a USB/SPDIF converter. I sold it because I needed 2 coax inputs as I also wanted to include a transport.

Cambridge Audio makes a transport that seems highly regarded here on AG and retails for $500. Though I use a computer as a server most often, I am considering the purchase of one myself as I sometimes like to spin a disk. The idea of a dedicated transport, as opposed to a player, appeals to me.

 
I should add that I also got back into audio, putting together a new system once retired. 
Yes, keep us posted. Always nice to hear feedback, once suggestions offered.
The Teac UD-501 is, IMHO, the best (used) bang-for-your-buck DAC under $500 right now.

Here’s one on USAudioMart for $375: http://www.usaudiomart.com/details/649325716-teac-ud501-dac/ (no affiliation).

I own one and it’s a stellar performer! It replaced a Schiit Bifrost.
