A few months back when I was playing a CD with lovely deep bass fairly loud (but not TOO loud) on my Summits, the left panel stopped working. I got advice from ML and with the help of the good wife (who has better eyes than me) we figured out how to remove the panel and swap it over to the other speaker to diagnose the problem. It still didn't work, so ML suggested I needed a new power supply, which I bought through the local (NZ) ML agent. Two months later the part turned up but meanwhile, life had moved on! When a local distributor heard about my lack of speakers he let me borrow a couple of rather nice Gauder Akustik floorstanders. But when I plugged my power amp in there was no left channel. Hmm! So, I then plugged his power amp into my Summits and BINGO! My speakers were working fine! I assumed that somehow my diagnosis had been faulty and that it was my amp that was the problem all along, not my Summits. Good old ML! About a month on and I bought the rather excellent AVM amp and the Summits were sounding AMAZING. Until last night when I cranked them up on an electronic record with low bass and... the speaker's panels stopped working again. So it WAS the Summit after all. But somehow, it started working again. I turned everything off last night (at the wall) and this afternoon switched the cables around on the amp just to see. Bingo! Both speakers worked. For about 10 minutes. Then the panel stopped working again. So... (deep breath)... anyone here technical adept or experienced enough to have an idea of what's wrong? I've got an unused new power supply that I could try if needed, but given the scenario, is it likely that what's wrong IS the power module? Or perhaps faulty wiring to the panels? Thanks in advance to anyone who is kind or foolhardy enough to reply to this!
