When I read statements like, "ruthlessly revealing," and "very fast sounding," the first thoughts that go through my head are: distortion and elevated mid-treble. I've owned speakers renowned for their speed and revealing detail, and I can't argue that they sounded fast and revealingmost of the timeuntil you get that piece of music or recording that truly reveals that speed and that detail is really artificiala product of too much mid-treble or too much distortion. And measurements confirmed what I heard. After listening to many ESL, ribbon, and planar designs, I've come to the conclusion that exotic drivers are rarely worth the cost in dollars or the cost in trade-offs. There are exceptions. I love the sound of ESLs and Maggies, but there's no getting around the large panel trade-offs.
