Some slight hiss at higher volume settings with music muted. Not a factor when listening. I am, however, less sensitive to hiss issues than are many others.

It is said to be upcoming shortly.

AMP3 DESIGN PHILOSOPHY: The AMP3 is the first product to be introduced to the audio marketplace by Hisoundaudio, a China-based company that, by their own description, is dedicated to producing audiophile-grade players that incorporate the oriental concept of music and art being inseparable. The AMP3 is designed to address the audio shortcomings of the current portable audio marketplace. Its design goals are to produce a player that incorporates the following characteristics: sound resolution, separation of the sound stage, a sense of power, and the flow of the music. Hisoundaudio flatly states that it is their design goal to produce audiophile-grade players that are second to none currently produced! Quite a lofty goal, with a lot of tough competition in the portable marketplace to challenge their claims. Given this design philosophy, needless to say, I was very interested in evaluating the AMP3 and comparing it to a number of other high-end portables, as well as using headphones and IEMs other than the included PAA-1 earbuds (which were designed to complement the performance of the player).
