Thanks Ronnie. Great start. I'll do some testing and post when all my kit is ready. I recently built some 1TB iPods to use in vehicles. These work very nicely with iPod friendly systems, plus charge simultaneously due to the direct connection.

My next plan is to use an external battery with E2 and iPod & iPhone to see what I get.

There other Digital Audion Players (DAPs) out there that I may also try in combo. Astell & Kern, Cowon Plenue, ..... Anyone utilize any of these or others?
