Good evening ladies and gentlemen, I am in the search for a portable amp and am seeking recommendations. I appreciate good sound although I can't say I have golden ears. Most of my music collection is in the iTunes plus format and with my ears, I could not differentiate the difference between that and ALAC in a double blind test. That said, I am all about the best bang for the buck and have settled on three headphones that satisfy most of my needs - Sennheiser x Massdrop 6XX, Sennheiser 25-1 II and JH5. The Sennheiser is almost permanently hooked up at home to a JDS Labs O2. I am looking for something that will power the JH5 and 25-1 II while at work and on the road. I understand that neither are necessarily difficult to drive however I am looking for something that will help refine the sound. I don't necessarily have a budget but I generally don't want to spend more than $400 unless I can really justify it. Since my iPhone 7 is my primary DAP, I also really don't want forty dongles in order to get the damn things hooked up. From my research it looks like a Dragonfly might be a good bet although I would have to utilize a lightening to USB adapter. I have also read that the Q1 and Q5 are worth looking at as is the Mojo, however the Mojo may be priced higher than it's performance. What say you Head-Fi?
