So I need a rig and have decided an ipad/ipod/mp3 setup is what I want to go with. I did a cheap laptop with a cheap interface and it sucked.
So here twas what I was thinking:
mp.3 (iphone or ipad depending)
1/8" trs to RCA red white cable (short, but will get something decent quality)
vic firth headphones (I like them)
headphone amp (not really sure what to do here, kind of need my stupid HP4 fixed, but if not something small is what I'll try to snag)
Art DI with some other cheaper DI for backup that I already own because it's cheap to replace if lost or broken.
And for getting the signal to proper line level this little device art makes:

Although I don't know if the DI is necessary with the device above unless long line level runs are a bad idea.
I like this idea because of how small it is. All that crap would fit in a guitar case or cymbal bag.
