Full transportable setup (as in throw in bag or large trench-coat pocket):
diyMod iPod 5G Video 30GB
diy Sonicap dock with Mini and RCA outputs, all Cardas wiring
diy PPAS (AD8066/AD825 opamps, 3x LMH6321 buffers on 8AAA rechargeable batteries)

Portrable setup:
Same as above except dock is diy BlackGate dock in Cardas:

Headphones for both are impedance modded and recabled KSC35 on PortaPro headband with HD414 pads. Everything is held together by a hair-band shamelessly stolen from girlfriend.

To say the least, it's the least expensive and best setup I've ever heard
