Jay - Thanks for the detailed summary regarding the differences between the NX-Oticas and the Super-7s. These are the two designs that really intrigue me. I'm leaning toward the Super-7s because I like the one-box design and the styling, and have always been a fan of planar drivers.
All the Super-7s I've seen photos of are painted. Do you think it's reasonable to considering veneering the side panels (and maybe the top of the baffle where it's exposed above the grill), or do the curves make this impractical?
