Did the receiver because of the positive opinions as a stereo receiver to operate high-quality speakers. Sound is not the world in the Pure Direct mode. FM radio, MP3 and USB Internet Radio can not inspire me. The sound is hard upper midrange is too strong, upper bass is too weak. The Einmessmöglichkeiten I have not tested. I need only linear amplification without sound distortion with good speakers. In the price range can not ask for more at ease. Unfortunately, there are hardly pure stereo receiver with many entrances.
