System problem


Hi all, wonder if anyone can help me here. Was listening to my system last night at a pretty high volume level. I went to turn it down to shut it down for the night and when I hit the down volume button on the remote the system dropped in volume and went almost mono sounding. Both left and right sound the same. Like someone put heavy. heavy blankets over the speakers. I thought a tube had blown in my preamp so I replaced them with new spares and no difference. Today, I plugged my monoblocks directly into my DAC/streamer and the same thing so I’ve eliminated my preamp as the culprit. Any ideas? My system consists of Wilson Maxx 3’s, Classe CAM600 monoblocks, EAR 912 preamp and PS Audio Directstream with Bridge 2. I won’t mention my turntable setup as I wasn’t listening to it when this happened. All drivers in the speakers are working, there is just minimal and muffled sound. Any suggestions would be appreciated. Thank you

Initially, it sounded like you may have blown a combination of the tweeter and/or the midrange resistor fuses in the speakers. But you say you can hear every driver. Then it can only be the power amps. Perhaps they throttle down when overdriven.
That's my thought right now, or the Directstream. When I plugged the Directstream directly into the amps, I used the monoblock interconnects, not the DAC ones and the same problem persisted. Will continue to troubleshoot!!!
About that turntable... did you play through it to eliminate the DAC as the culprit?
Today, I plugged my monoblocks directly into my DAC/streamer and the same thing so I’ve eliminated my preamp as the culprit.

I'd definitely check the tubes and fuses in the EAR 912.
?🧐?


I will play the TT tomorrow night to see if that's the problem or not, as for the EAR, I plugged the DAC directly into the amps bypassing the preamp and the problem was still there. Will update tomorrow
