Hi all, all the best to everyone in 2019!
I have had a couple of problems with my DACMagic-100 with the first about 6 weeks after the warranty expired. This was the common (overheating) failure of the wallwart power supply.
I contacted Cambridge via e-mail and after giving the serial no. received a replacement by return post (48Hrs). However the D-A converter itself threw a wobbler about 8 days (3 hours use with new PSU) after. Now it will not sense USB/Opt inputs and the USB select LED just constantly flashes rapidly. If another source is selected the whole thing goes potty, flashing all LEDs at random or all together. Since purchase a little over 12 months ago (NOV 2017) the device had barely seen 20 hours of use as I work away from home quite a bit, sometimes for 2-3 months at a time. I suspect that the first PSU failure may have contributed to this *secondary* failure. Unfortunately I have no local repair techie to take a peek or carry out a diagnostic check. This does not inspire confidence in a like for like replacement. Now to find a budget replacement!
