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.

Monterey, if you think the DAC in your Yamaha is superior, you will be shocked at what a newer DAC, stand alone, with the latest technology and higher BIT rates will sound like.

If you want improvement buy a stand alone DAC.

Look at Eastern Electric MiniDAC, Musical Fidelity M1DAC, or a used Bel Canto DAC 3.

You will get huge bang for your buck.
Garcia cracks me up yet again.

I say keep the Sony DVP S7000 sell the other CDPs you don't need/use and get an external DAC. At $500 you have a lot of options. Over $500 there are even more. To me 9 CDPs sitting around the house not in use isn't a good thing. Sell a bunch of them and take that money and add onto your $500 budget and get a DAC with a good quality Coax cable.
Source (CD player, or other Digital Source) -> DAC -> Preamp -> amp -> Speakers.
so the cd player connects to the DAC via a toslink and then the dac to the preamp(yamaha) via RCA?
