At least in my country, where power is not stable nor clean, electrostats' mortality rate is high. Most friends whom I know possessed Quad 63s and Martin Logans have had breakdowns, some fixed, some eternally doomed. That is really the main reason why I still shy away from stats. I must say hearing Quads and MLs, (lately the Summit) they possess a liquidity and presence that I don't hear in my Maggie. They push the proverbial they-are-in-the room bit to the max, imo. And they are fine sounding, with utter lack of grain. The Summits can be pushed hard, and play loud and even fill a medium to big room, and they stay fine, unlike my Maggies, they can sound a bit grainy when played loud, at least my model. One thing about Maggie that I have discovered only lately, when they are driven by powerful amps, like a Hegel H4 which a friend brought over last month, they become another animal. It's like water falling out of Niagara falls. Music comes out with so much ease, and bass punch and power go a few notches more. 600+ watts into 4 ohms is nothing to sneeze about. The Summits sound lovely but until I hear better stories with their behavior vis-a-via our power line quality, I'm putting them on hold.
I'm guessing it has more to do with humidity than power quality. Or maybe a combo of the two? Most electrostats do not do well in a highly humid environment. The Philippines are very humid from what I understand. Roger Sanders of Sanders Sound says his stats can be used in humid climates. You may want to look into them if you want to use electrostats there.
