To remedy the "sparkle" problem, you need to know that the electrostatic panels are essentially dust magnets. You should do some periodic maintenance to them every 6 months or so.
1) Pull the plugs on the speakers, and let them power down for a day.
2) Then, vacuum them, gently, and on both sides.
I used to have ML Sequel II's, so I know the wonderful sound that can be had from them. I also know that when you do get tired of the sound, that it is time for a change.
After 14 years or so, I upgraded to the Revel Studio. They are a much better speaker, although, I had to pay four times the money for them, and I had to double the power of my amp! The Studios image fantastically, and have better bass. They can also get LOUD! Something the ML's were not able to do without sounding brittle.
Good Luck in your search. If you do decide to upgrade, give the Revel line a try!
