I was long looking for a BluRay Player priced does not belong to the luxury models. This BluRay player has everything you could wish for as a film lover of a BluRay player. The image quality and the sound are really very convincing. The image is sharp and has a very convincing color reproduction, even without the correction mode switch. The tone can optionally be output as a bitstream or PCM.
One should look not only BluRays but also DVD's, then this player offers excellent upscaling that comes almost to a BluRay zoom.
The 4k upscaling I sadly can not say because I do not have 4K TV.
Otherwise, the BluRay player is excellent value for money.
