Few people in the audio business would deny that John Curl is an audio design genius—arguably the greatest one of our generation. He designed and built the electronics for Mobile Fidelity's SuperMaster and David Wilson's (of Wilson Audio) UltraMaster tape recorders, two of the three best analog recorders in the world. (The other is Keith Johnson's home-brew unit.) He designed the JC-1 head amp and JC-2 preamplifier sold under the Mark Levinson name some years ago. He designed head amps for SOTA, Michaelson & Austin (TVA), and has done consulting work for more high-end companies than you can shake a stick at.
