can i improve my system with a better cd player?


I upgraded just about everything except my cd player. I just use my old sony dvp s7000 as my cd player. In the past I thought all cd player were the same until yesterday when I tried using my ps3 as the player. I instantly heard a big difference. Now I'm thinking I can actually improve my sound by buying a new player can someone recommend something under 500 buciks? I like buying used since my system is dated itself but it still sounds decent to me.

Sure thing. Buy a modest vinyl rig and you'll hear the difference vinyl brings to the plate. I've a so called 'hi end cd player'. I've also got 6 turntables. End of discussion.

That ain't gonna help with his shiny discs, now is it?
now that i realized that my yamaha dsp-a1 is doing all the DAC, will the rotel improve my system if I connect it via RCA?
This is a painful purchase because I just counted how many CD players I already have in the house, NINE players! All I need is another one lol.
I couldn't tell you about that comparison. But, why not try the better of what you have, hook them up with both connections, and A/B each ones internal DAC against the Yamaha
DAC and see if any of them fit your needs. If one sounds a lot better, there's $500 for something else.
