finally i had the time to make a measurement of the frequency response of the Ca-Fi:
All equalizers off, tested with the build in Music-App and Poweramp.
It is bad, really bad. Worse than the original HU. For those who do not know these kind of measurements: If it would be good, the frequency response would have the same volume in every frequency, in that case the line on the picture would be like this ----------------------------
But the Ca-Fi is loosing -6db at 200hz and is boosting +7db at 50hz.
If you are not so into Hifi, this is not really a problem. But in the eyes of an audiophile....
Before puchasing this unit, i asked them if the frequency response ist linear, they said:

Hi Stefan,
It is linear. The shipping normally takes less than 5 days.
