As a longtime electrostat owner and dealer, I'd have to say that this is not the ideal technology for hard rock at high decibels.
In my opinion, one effective way to get where you want to go is to use a high-end speaker with pro-sound drivers. Examples include PiSpeakers, Klipsch heritage series, Classic Audio Reproductions, Edgarhorn, vintage Altec, and two other brands that I happen to sell (don't want to turn this post into an ad so I'll mention who they are in an e-mail). The advantage of prosound drivers is they have excellent dynamic characteristics, and the disadvantages are they are usually not as smooth as high quality high-end drivers and being high efficiency will require a pretty big box to get good bass extension. In my opinion the better designs sound very smooth, but the box size issue remains. However, if you're considering Martin Logans, you've already conceded a fair amount of real estate to your speaker system.
Best of luck in your quest,
Duke
