The D2's battery still last for 50 hours music playback...
And I also said that it will be bullet proof

Hmm...

Source: Dissected iTouch/iVideo with OLED, 64GB flash, iModded
Amplifier: DIY cMoy with audiophile grade capacitors and dual OPA627, running off a couple of thin lith-ion batteries.

Have both the source and amplifier housed in a carbon fiber enclosure, not much bigger than the size of a small 2.5" SATA harddrive enclosure (twice the thickness is fine by me).

Headphone wise, any flagship IEMs or earbuds, like Ety's ER4S, UE's customs, or Yuin's OK1/PK1.

Sounds achievable.

My realistic dream portable rig would be similar to the Sansa Fuze with at least 64GB internal memory and a SD slot. It would D-Pad type controls instead of a scroll wheel. It would have great battery life, 30+ hours.

It would run RockBox and have a true line-out. I'd match it up with my W3s and use my RSA Predator when stationary.

Finally, it would have a compass in the stock and a thing which tells time.

iPhone with built in amplifier for the Stax S-002 (custom mold closed back S-001MK2 successor)

My dream system is close to my now portable system: Cowon iAudio7 (16 GB) and modified Etymotic ER-4P. Additionally I would like at least 32 GB of memory and a conventional joystick operation instead of the touch controls. A sonically even better headphone output stage would be great, also a fully parametric equalizer instead of the semi-parametric one.

My dream system would be a complete nanotechnology-based audio system that interfaces directly with my brain/nervous system. No need for any external hardware.
