of experience with electrostatic speakers, including Quad ESL63s and my self-built units. I also have two sets of Koss ESP/950s.
The only thing I find lacking in the ESL63s is low bass response. The ESP/950 headphones sound almost exactly like the speakers (ultra low distortion, perfect transients, smooth frequency response) except that they add the deep bass that is missing from the speakers.
I don't have any problem with good dynamic headphones (I like Sennheiser's top of the line models and find them comparable to the ESP/950s).
I settled on electrostatic technology as the way to go (for me) about 15 years ago when I was doing research into speakers and started building my own electrostatics. Prior to building my own, I never had an opportunity to listen to electrtrostatic speakers. The first time I heard sound coming out of one of my test drivers, I was hooked.
Even though I am big on electrostatics, I am the opposite of a high-end snob. I like CDs better than vinyl. I like solid state amps better than tubes. I am not a believer in cables, green pens, and other audiophile debris. I don't think it makes any difference whether an amp is in a bronze and spruce box (suitable finished with violin lacquer) or your run of the mill aluminum box. I'm not convinced that there is much audible difference between amps with similar specs. I'm not much of a believer in subjective evaluations of equipment.
I have two cars. A honda Odyssey minivan and a BMW 525. Of the two, I prefer the Honda. It is far more reliable and much less expensive to repair, and more comfortable on long trips. When people ask me, I usually steer them away from BMW purchases.
I generally avoid "fine" wine and gatherings of people who love it. I lived in the bay area for about 7 years and can't tell you how many times I went out with friends where the self-proclaimed wine expert in the group had to select just the right $75 bottle of wine to perfectly compliment the $5 hamburgers we were eating. When I moved to Texas I'm not sure if I was happier to move because of the income tax or to be free of wine snobs.
So, all in all, I don't think that electrostatics turn people into snobs. Some people have that sort of thing in their personality and it only takes the right thing to bring it out (cars, wine, audio, art, food, women, and etc.).
