I am looking to replace my ipod classic 160gb with another DAP (ipod is getting old). I have a pair of heir audio 4.AI and run it into a rendition 1 headphone amplifier. I just want the most clear and most neutral sounding DAP. Can anyone give me recommendations, I really like the Cowon Z2.
Also it has to be expandable via sd or micro usb... i have a ton of music
