SUPPORT / MANUALS
Great sound from this device and is able to drive my diverse collection of headphones including Grado, Hifiman, Oppo, and Audeze!
ARM2 is exactly what I was expecting. The sound is clear, loud and without distortion. I installed Spotify but cannot install Amazon Music Unlimited. Even the free Spotify version sounds impressive. I use it with Shure se215 and se425. The quality is way better than my iPod.
Better than even expected!!!
Easy to use, easy to transfer music. Best of all? By far the best quality music player that I have ever had. Great sound, paired with my in ear quality earphones. Thanks for a great experience. Fast shipping. and better than expected.
