Pour conclure, sous des dehors discrets le DAC Sony PHA-1AEU offre d'excellentes performances sonores avec un amplificateur pour casque dont la puissance, si elle n'est pas démentielle, permet cependant d'en profiter pleinement. Un Qobuzissime mérité.

I've been looking for something to give the music on my phone and Ipod (yes, I still have one) a little more backbone. The Sony PHA-1A is exactly what I've been looking for. It's small enough to be easily carried around but it produces a BIG sound.

I use the PHA-1A to play FLAC file 44-192kHz from Nexus 5 mobile phone and Samsung Tab-S tablet, both android. I use the USB Audio Player Pro application on both. I connect the PHA-1A to both devices with the supplied cable (Sony says very little on compatibility, seems the cable is micro-usb to...

Overall Impressions This is a amazingly looking device, it does not matter how you look at it, it is simply a pleasure to look at. That is the first impact that one have once you look at it, it calls your attention, I even make a point of not keeping it visible when I’m on the go.

Extremely limited application. I plan to return for refund. Team has a similar product with more broad application.

Works well. Clear sound. Not fatiguing. Excellent construction. Holds battery charge well. Lasts only around 6 hours hence 4 stars.

I was intending to buy a new Fiio x5 mk3 with an external amp but decided to try this paired with my underused Ipod 6g as it is a somewhat cheaper option. The standard apple cable connects into the usb socket on the base of the PHA-1EU.

I recently purchased the Sony PHA-1A. I have this coupled with the Sony NW A35 a hi-rez player. I was a bit skeptical that this would significantly improve the sound. However, I was pleasantly surprised. The Sony PHA-1A provided more detail and clarity.

I own both this Sony and also the Teac. They are both terrific pieces of equipment and greatly enhance the listening experience and I actually recommend both. However I will give a slight edge to the Sony in that it does provide an even clearer and more precise interpretation of the music I listen...

    Great music enhancement. Really makes your headphones pop.Light weight. Good battery life.

    Kind of expensive but if you're a real headphone fan they are well worth the investment.
