The Signature 30 + AKG K1000 headphones seems to be getting quite popular (lots of emails about this combo)! The modded iPod + Sig 30 (or Clari-T) has fantastic synergy and this is what I'd call portable.
Hi Loftprojection,
It won't be hard to kill Steve Job's "baby"

I'd love to give them a listen! If they can be powered on SLA battery, they can be portable...just add your RWA modded SB2 and you'll be set! 
Cheers!

Don't worry, I have no interest in building a big boom box, I was just joking around!
Yes there is growing buzz at head-fi about the Sig30 feeding AKG K1000. Man, if head-fiers discover your products, be prepared for the next step, you will need a full fledge manufacturing plant. I told you before, your next step is headphone amps!
