CitarExcellent audio output
The Samsung Galaxy Alpha does a great job as far as the quality of its audio output is concerned. The smartphone did a perfect job in the first test (the one where it's connected to an active external amplifier) and got amazing scores top to bottom. It also showed above average volume levels for an all-round audiophile pleasing performance.

Plugging in a pair of headphones didn't do much harm either - outside of the limited spike in stereo crosstalk, the output didn't deteriorate even a bit. Outside of the HTC One mini 2, there's no better performer than the Galaxy Alpha in this class and let's face it - the HTC smartphone is better than just about everything else on the market right now.

And here go the results so you can see for yourselves.

Primero que todo, disculpen por el desorden de lo que deberia ser la tabla, ya que mis conocimiento de herramientas de foro son limitados.

Sobre el tema, pongo esto sobre el Galaxy Alpha para por medio de las opiniones de ustedes, ver que tan bueno es realmente en calidad de audio. Y algo que no me parece bien de esa review es que solo comparan con mobiles recientes y del año pasado, lo cual no deja saber si es mejor o no que un iphone 4s y de si es el mejor smartphone para audiofilia o en que puesto quedaria de un ranking general.
