it wasn't faulty wiring from the amplifier, because i double checked that. i kinda had the suspicion that it was faulty mp3 files, but that went out the door when it also happened on tracks that i had on the unit for some time....i do get some problems occasionally on the syncronization of the empeg. the player fails to restart if i am transferring alot of files, and i have to do this via usb, because i have yet to get a crossover cable. is it perhaps because the synchronization fails to fully complete?
