I have the E17 Alpen ordered with dm Qogir E09K, because I wanted to use the E17 firstly as DAC with my smartphone (Sony Xperia S) and the other in combination with the Docking Station the FLAC files that streams my Squeezebox optical over the Input the E17 Wolte send a supposedly better DAC conversion. In addition, the variable preamp output would be the dock temporary P200 precursor to those of the repair will be back for my Onkyo. Unfortunately, the parts went to 2 pieces back trial heard. Preliminary but: The processing is really top and makes a very sophisticated look. First test the Xperia S + B & W P7 The E17 as a pure HP amp is not really useful. Although it amplifies the signal, thereby the sound but not better (As well as?) As a DAC does not work on the E17 Xperia S (has USB OTG) despite Adapter L7. Next try in the dock over Opt. Cable connected to the Squeezebox as DAC Headphones (P7) alternately into the dock and into the headphone output of the preamp (Onkyo P200), which receives its signal directly from the DA converter of the Squeezebox. The difference is enormous. The E17 solves fine on but it sounds cold and pointed, partly tinny The Onkyo solves just fine but sounds more harmonious and coordinated. In brief: The E17 annoying (me!) The question is now for whom the device is intended and where the so-positive reviews come from? It all depends on where you come from hörtechnisch. It has so far only with cheap kofhörern 128 Mbit Mp3 heard from the smartphone, the E17 may mean an increase. But we know how good music can sound when it produces good (!) And is then reproduced without Verfälschiung, for the E17 is definitely a step backwards or a disappointment. At least that is my personal impression and I would advise everyone the money first to invest in good headphones, then you can rausholen even from smartphones something - assuming, of course one has purely done it before, that is Mp3 least 320 Mbit or better yet Lossles material.
