interesting comments gonglee...i'm a classical music fan and that's exactly the reason i went to electrostats...well, i can tell that you probably never heard Innersound electrostats with classical music...there is no metallic sound and the chamber music or piano/violin solos are absolutely envolving...one thing though...the Innersounds, due to their narrow sweet spot, can not do justice to full scale Mahler, but i can live with that...
