Cd Player Choices To Match Up to Vintage Electronics

Hi all, would appreciate a few choices to start looking at to upgrade my secondary system. In my man cave I have a system I listen to when I'm working on hobbies. I acquired in a fit of nostalgia, a Yamaha Integrated amp CA-810. I had one in the 70's and 80's. I just recently bought some Wharfedale Diamond 225 speakers for the system and might be looking for a better cd player. I am currently using a Yamaha CDC-685 five disc change which is nice for long periods of listening.. Sounds good but of course always looking for better.  I want to stay within reason expenditure wise since the electronics are vintage. What would you guys suggest?
