Art Dudley has posted a review of the 47 Laboratory’s Model 4730 Midnight Blue stereo FM tuner ($1500) in his Listening column at Stereophile. His conclusions:

To accept or even embrace distortion is not to love it, but rather to understand that the technology of music recording and playback is a continuum—and a nonlinear one at that. Some find beauty in every bead on that string, while others pitch camp where they are happiest; either approach is fine. ”
