Said in advance, the sound of the set is very good. Unfortunately, that will not help if the built-in amplifier is defective after a short time. In my set, it was the left channel of a few days had problems with the Laustärkereglung. I turned louder he became, for example, instead only quieter then to be equal to much louder with further Lauter Switch. The set has been changed twice, the error occurred in each set within a short time again. Therefore CIH would infer a series error because maybe defective components were used or so. Ultimately, I had to set back as hell could not deliver error-free.
