I had a similar problem not long ago. No matter what I switched around the left channel was weak. I thought something in the crossover had gone south. I eventually used my phone to measure the speaker outputs, and BAM, they were exactly the same! Turned out my left hearing aid was malfunctioning.
Left Channel Blues
After three and a half years of listening to my MA252 through SF Olympia IIIs with virtually no problems and much enjoyment, at least 4 times in the last 2 weeks, the left speaker goes very quiet and really crackly or fuzzy.
So, unplug receiver, unplug speaker cables from receiver, then unplug cables from the speakers . . . wait 5 to ten minutes, reverse the steps above . . . AND it’s like it never happened.
Today, I listened to cds for 3+ hours, all good, then, power up at midnight . . . Poof . . left channel gone again.
Speaker cables are Maze Audio (rip David) Eden series 12 gauge copper twisted pair configuration with 14k banana plugs on both ends.
What gives ? Thoughts and recommendations will be appreciated !
This time after unplugging all cables, I will switch left for right speaker cables to see if right channel goes out . . . which hopefully will identify if problem is speaker cable or the amplifier. Thanks all.
