My Panasonic personal CD player, which I've had since 1999, finally died. In trying to replace it, I've discovered there are very few models in 2012. The best option seems to be Sony's DEJ011 Walkman, which I picked up today. It's okay overall, but I find the sound quality to be a bit lacking (though it's not terrible).
Are there any options for improving the sound, such as an external DAC equivalent perhaps? A Google search has really only turned up larger DACs for receivers or soundcards; I'm looking for something a bit more hand-held that would be appropriate for a smaller device and would work with an analog-out (headphone) port, as it doesn't have a digital or optical out. The Panasonic had one, of course.
I'd really like to find an option as I still enjoy listening to CDs under headphones. Much thanks
