Blackbody Ambient Field Conditioner http://www.lessloss.com/blackbody-p-200.html Price: $1323 Awards won: Stereo Times Publisher's Award 2010 This one claims to absorb EM radiation and prevent 'harmful' EM radiation from reaching your audio equipment. Full marks for aesthetics though, nothing to fault there, Lessloss deserves credit for the design. You can see how the blackbody got its name: by absorbing any EM wavelength, and by radiating none in our visible bandwidth, the device is as black as black can be; you might even say it is blacker than black, since it’d be the absence of light radiation altogether. Our version of the blackbody is not wired to gear and contains no batteries or power supply; instead, within the device is a special reflector whose emission pattern approaches that of the ideal blackbody radiator. By creating this near perfect blackbody, we’ve created a device that, simply by being placed in your gear’s ambient EM field, will absorb virtually any EM radiation at that location. There, gear will no longer be able to bounce EM radiation off proximate objects, only to have it return to influence its delicate signals and degrade sound quality. The Blackbody’s EM radiation pattern lacks a distinct spectral signature, making it impossible for its own radiation to cause sound coloration.
