Initially, I thought these looked interesting but specs & descriptions give little real information. Where are the performance graphs that tell us the tonal response and which frequencies have the worst distortion? Sorry but if a company can't be bothered publishing normal data for high end gear, I can't be bothered even considering their products.
Valensilius_ZephyrusOne can waste their life researching products so no, the information needs to be provided straight up or I'm no interested in dealing with that company. If the company isn't interested in doing that, they loose a sale.
