I have been using MC21 with my Chord Mojo to a Class D amp to my KEF speakers for sometime now.
This morning, something happen and I sure hope I did not destroy my KEF tweeter/midrange drivers.
When I was listening to a song at a relatively low volume, the sound just turned into a extremely loud "pink or white noise" type sound! It was almost at full volume or basically at what I had stated at maximum volume (75). I was so shocked that it took me a while to react. I switched off my amp and waited a while. I switched off the mojo and checked JRiver. It seems like the USB device was not detected by JRiver, But I just rebooted the system and prayed my tweeter was not blown. Everything seems all right after the reboot. Not sure exactly what happened. JRiver/Windows lost connection to the Chord? The chord seems to be working and the batt is almsot fully charged when it was playing. The amp? Did not seem like a problem. I checked all the cables and everything seem intact. My speakers seem ok. I was luckily around when it happened. If I was at the toilet or out having a snack, I am sure my speakers would have been blown.
Any ideas what could have happen and how I can prevent this? Makes me worry about the reliability of a PC based system now....
