Yes a player and its either internal or external DAC will can make a big difference. Let us know the rest of your system and then it will be easier to recommend something synergistic.
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.
