Few people in the audio business would deny that John Curl is an audio design genius&mdash;arguably the greatest one of our generation. He designed and built the electronics for Mobile Fidelity's SuperMaster and <A HREF="http://www.stereophile.com//interviews/478/">David Wilson</A>'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.

If there is indeed a renaissance of tubes in high-end audio&mdash;and it is clear there is&mdash;much of the blame lies with Audio Research Corporation.
