Jon Eben Field has posted a review of the Bob’s Devices Cinemag Sky 30 step-up transformer ($1250) at Wall of Sound. His conclusions:
“In listening to the Cinemag Sky 30, I was distinctly aware that this device is not an emotional instrument. It is, rather, a transparent, analytical, and musical device that reveals a tremendous amount of information in the details of a recording. The Cinemag Sky 30 is extraordinarily good at opening up a soundstage and placing instruments within that space with a clear sense of the air around them. Imaging, detail retrieval, intimacy, resolution are all qualities the Cinemag Sky 30 has in spades.”
