Remote control in addition to on / off even the volume and source selection. The position of the volume control from a distance is hard to see (is represented only by a thin black line on the knob). The audio source on the other hand indicated by a light spot. When amplifier is switched off, however, is not thereby identify which source is currently selected.
Can really liked the automatic shutdown if no signal comes from the selected source. The period of about 30 minutes should be a bit shorter but mE. Also very useful is the switched power receptacle on the back, which is live only while the amplifier and to which one can connect any audio source such as a CD / DVD player or a tuner.
The sound qualities can manifest itself only subjective, because these (including installation) and the nature of space can be strongly influenced by a lot of parameters such as loudspeakers. For my personal perception of PMA 520 AE comes with a very balanced sound for all musical styles and much practical transparency in considerable dynamism. (You can hear where the cello sitting ...) He is also at higher volumes never strained, therefore, but also develops its good sound effortless and unforced.
Overall, for the living room at home a good device for a cheap price.
