Well I'm pretty excited my JDS Labs C5 showed up today talked to the guy before I ordered, got a e-mail from him last Friday saying they were behind in production, and that it would be assembled on Monday and shipped. It showed up today. I will be using 2 Ipod touches, a Ipod classic, a Iphone, my Samsung S4, and my Sony CD Walkman player for sources. Everything is crammed packed with tunes which means I have thousands of selections for on the go not to mention the Cd's that I can play on the Sony. Its about the same size as the Ipod classic only a little thinner its charging now. I will report back on how it sounds soon. my on the go amp pretty excited. Thanks to Endershadow for all the suggestions.
