portable media player - multiple output?

[Simeon Harris <simeonharris40@googlemail.com>]

chaps, i know this might be a long shot, but does anyone know of a
portable media player with multiple outputs? i'd like to be able to
play one stereo pair (a backing track) through one set of outs and a
click track through another (headphone out would be best). i've been
using ableton on my laptop to do this, but i'd really prefer a small
portable hardware device, if possible...

cheers
