In the last week, I have gotten new headphones (Audio Technica ATHM50's) and I ordered a Fiio E11 portable amp witha LOD for my itouch 1st gen. The amp is great but it does not allow charging while in use and I have had the batteries run out on me during the work day. I spend most of my day at my desk (at work) so I can plug my amp in while in use. I have seen the other Fiio products (someone else at work has an e6 that can be charged while using it), possibly the Fiio e9, and others have mentioned the Portable Amp v2 as a good alternative. I guess I am looking for suggestions for a decent amp under $100 that I can keep on my desk at work. Any thoughts would be most appreciated. Thanks!!!
