I need to know as making an amplifier with a port USB as music storage in a memory Flash, which circuit integrated as independent DAC can use could give me some diagram that could use.

Digital Music Player with Amplifier
 

Try this MP3 Player with LCD Display

This project is a stand alone MP3 player, designed for home, car, or portable use. It plays a group of MP3 files stored on a standard or laptop IDE hard disk drive… hundreds of hours using even today’s low-cost drives.

The firmware is available under the GPL, for anyone who want to really customize the player. High quality audio output is provided by a 24 bit DAC, using both standard line-level outputs and an amplified headphone output.
