Kharma Matrix MP 150 issues???

May anyone know the issues?
I'm having a small issue with my kharma system and wondering if you can help? I will try to expain the best i can due to my poor english. First, when i turn the system on and play for 10-15 mins. I hear a LOUD POP sound out of my right channel speaker. Than, i know right away my right Matrix 150 right side amp LED light turned off. I ran over there quick and turn the power off first. Than, i check the fuse box and the fuse was ok. This don't happen too offen, but now i am very worry it might pop again when turn back on. So, it did pop again after i turned back on for 5mins.

I am guessing it could be a cable connection was shorted? Just guessing? My friend is saying it could be a DC problem? which i don't really know what that means? or, it could be a simple issue that i don't even know how to fix? So, i decide to email for help. Will you kindly and help me resolve my issue? I'll be very happy to provide more detail if needed.

I hope i'm lucky and get it fix soon. I will be patience and wait for your respond. Many thanks to the person reading this.

Kharma CRM 3.2 speaker
Kharma 1.0 subwoofer
Kharma Matrix Mp-150 Class D mono amp
Conrad johnson ART dual mono preamp. Just re-tubed nos with Telefunken

Hello from Canada. The Kharma Matrix MP 150 amps have a switchable DC buffer that is installed but not switched on. The amp sounds better with it switched off but some tube preamps will leak DC and stress the amp. If You fix the CJ preamp and the problem still occurs try turning on the DC buffer. I have the Nola Viper Reference speakers and am considering buying the Kharma amps to tighten up the bottom end a little. My Bel Canto EVO2i needs better grip. Looking for a good CD Player? Try the Meridian 808
or if Your CJ pre is dead then kill two birds with one stone and consider the Aurum CD/Preamp. All the best, Clark.
