Case color is different from the picture. More like other Orei products. There is no noticeable increase in noise. Although I have an HDMI switch that doubles as an audio extractor, that's why I use it. It doesn't seem to heat up at all, so heat won't cause premature death. No issues with the HDMI signal that I can detect. So far I have only used the audio output of the headphone jack. I have no experience with optical output (spdif toslink).
