No clue as of now. I used to know couple months ago...
What about this case: http://www.1964ears.com/products_accessories.html
Free name engraving!
Is that a stock lightning cable? Was it included with the Venturecraft DAC?
I have one of those, use it for my CLAS and Fostex HP-P1 from iphone 5. It is a Venturecraft lightning-usb. You can buy them separately, i think just under $60.
It's not stock cable but I got those cable when I bought DD Socket 1 from them.
I think foams are sold separately. You can something like UE crushproof case if not being water proof is not an issue. It has a uniquely designed system that secures your ciem well well.
Ok. Then go for a pelican or otterbox case and buy separate foam like this one: http://www.amazon.com/Pelican-Pick-Pluck-foam-Micro-Case/dp/B00091R0JO/ref=sr_1_3?ie=UTF8&qid=1372646494&sr=8-3&keywords=pelican+foam
