Hi,

I need some suggestion about the sound quality and amp using mobile phone and normal CD player.

I don’t know you have tried or not. This is my own experience just I got from my own CD player and mobile phone.

I just made an Dx-prc-I. its sound great means really beautiful when I use my O2 mobile phone to play the song, its like life quality. sound sharp, dynamic, voice is great but when I put on CD player, it’s gets flat sound, quality cut by 70% thou even the same song, no more louder then my O2 mobile phone.

I know mobile phone have an amp on output…..

What can I do to use my CD player to have same sound quality? Should I put a op amp or some things? Or other suggestion pls……

Pls write your suggestion.

Need explanation.

Thank you
Michael
