I always seemed to have some issues with electrostatics over time even in an environment with low humidity. I would eventually hear some rattling from the panel on certain frequencies. This has happened on Quad 63's, Logans, Acoustats, etc. After a while, I would listen for the rattle instead of enjoying the music. Based on reading various reviews over the years (since the 70's), I was led to believe that Electrostatic panels were the way to go sonically. However, I have learned over the years not to take too much stock in what you read. To my (experienced)ears, great dynamic speakers sound much more real than great Electrostatics, with far more reliability. I will say however that Maggies seem to be very reliable, the problem being their overall sound.
