Biggie:
I have heard a Wadia 302 + Omega II (SS), as well as Meridian 508.24 + Baby Orpheus among other electrostatic setups. I do not feel that electrostatics are capable of reproducing the "flesh" to instruments and vocals. An example of this is Ayako Hosokawa's "Bridge over troubled water". At about 3m28s in to the song there is a sax solo. With the HP-2's one is able to feel the warm air coursing through the sax, and being "shaped" by the valves. With electrostatics one merely hears the sound emitted by the sax. The same characteristic is shown with vocals, be they female or male. One is unable to feel the air from the vocalists lungs being shaped into wonderful melodies. Furthering that an ex-girlfriend of mine was a professional pianist. She was -incredibly- good. I spent many hours listening to her play her grand piano. I am very familiar with the sound of pianos in general having spent 100's of hours of my life listening to a variety of piano music. The electrostatic (and most dynamic) headphone setups I have heard were unable to reproduce the "piano" itself. I am talking about the physical object. Doubtless the electrostatics reproduced the "touch" of the pianist's fingers on the keys, as well as the strike of the hammer, and the vibrating strings. -BUT-, and this is a big but. They were never able to reproduce the feeling of having a grand in the room, never. With the aforementioned setups, I was never given the impression that I was listening to a physical object. Merely, hearing the notes viscerally projected from nothingness. It is this that pushed me away from electrostatics. I can tell you with absolute certainty that the only headphone setup I have heard that sounded "real" to my ears was the HP2 + MPX3 + Pythons + Meridian 508.24. Again, I can elaborate this further, but I feel I have given my opinion.
Kind regards,
Trevor
