I sorry to say that, to date, my experience with CEntrance and the HiFi-M8 as been less than satisfactory. I pre-ordered mid December and finally at the beginning of the month a HiFi-M8 eventually arrived. Unfortunately the unit I was sent turned out to be faulty. This was apparent within about 10 seconds of switching the unit on - intermittent crackling and spikes on the output, its particularly noticeable on the iDevice input. I was asked to return the unit to CEntrance which I did at some expense. All I'm getting out of CEntrance currently is "Sorry, but we're still trying to determine the cause of the problem" with no indication of when I'll get a proper working HiFi-M8.
The HiFi-M8 is now back with me and the issue has been sorted. There was a problem on the digital board which has been replaced.
