While I am not an owner, I have had the opportunity to listen to a handful of speakers that claim to be among the best in the world. Namely, a couple of the Wilson Audio speakers, including the X-2' and the WP8's. While the Wilson speakers are top notch, after listening to the Mira's and knowing how much they cost, it has to be the best deal in audio. They play loud and deep, measure really flat, have a super smooth and detailed top-end, and have exceptional finish quality, regardless of the MDF cabinet. Andy has figured a way to remove the cabinet from the sound reproduction process and what remains is a sound that not many speakers can touch. I think it may be the best speaker I have ever heard, and I have not had the chance to listen to Rockports flagship speaker, yet!
