After a couple weeks of use with UAPP and trying to see what if anything I could do to make using the red acceptable without having access to the UAPP drivers I decided to dust off my fiio e11. My portable amp of choice is my Cayin C5, however it isnt super pocketable and I choose to use it at times when sitting and relaxing. Anyway, combining the red with my e11 has proved to be more than reasonable. More than enough volume from my 32ohm V-moda m100's on Google play music, Spotify, YouTube,Netflix,HBO,Showtime,etc. And the size of e11 makes it easily pocketable for on the go use. Having an amp with the red for all around on the go use isn't IDEAL, however, I do notice the difference in sound out of the dac vs straight from headphone jack. Improved soundstage/separation for music as well as movies, etc. And the lack of extra battery drain is awesome. I own a fiio k1 tat works when connected to a usb hub, but the battery drain is ridiculous. Taking all into consideration, size, sound, battery drain, pocketability, Using red with UAPP for local music as well as streaming Tidal Hi-fi, and adding the small e11 when using other media applications, games, is worth the slightly less convenient feel,etc. Loving my red, still. V-moda m100,AKG Q701, V-MODA XS, Sennheiser Momentum,and continue to use with any other headphones I choose to add to the collection.
