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.

You would be better off to buy a new stand alone DAC, with newer chipset, and use your existing disc spinner as a transport. I would suggest looking at a Musical Fidelity M1 DAC which I believe is just a bit above your budget at $600, but worth the stretch if you can make it. The plus, beyond just the sound, it the flexibility it will give you to expand into digital music.
I am a little confused. You mentioned playing DTS CD and DSP-A1. Would
that be the Yamaha DSP-A1? And are you using the CD player as a transport
and let the DSP-A1 do all the decoding? If my assumption is correct. You
don't really need something with a great analog output stage and my
suggestion will be an Oppo BDP-93 for $500 new.
Another vote for the Oppo BDP-93 universal player. I have the BDP-83 and it sounds good and is well built.
I'd choose some great universal DAC with 24-bit capability and USB vs. CD player that will be outdated and loose its value speedlight fast.
Check out the new Grace M903 with USB, 24-bit, headphone amp and preamp.
I'm not sure which machine is doing the decoding, either the sony S700 or the yamaha dsp-a1 but yes the sony is connected to the yamaha and then to the b&k amp.
