Earlier this year I pried myself from my upstate-New York home long enough to visit Robert Lighton Audio: a beautifully decorated suite on the 12th floor of 37 West 20th Street in Manhattan's Chelsea district, in which an Audio Note Ongaku amplifier shares space with a Suzanne Guiguichon armoire, and from which the view of the Empire State Building is stunning.

For me, the highlights of any audio show are finding a room with great sound and visiting it often throughout the show, to relax and absorb a wide range of great music. At the NY Audio Show in April 2012 in New York City, it was the room occupied by the Valve Amplification Company. There, I fell in love with the sound coming through the Signature Mk IIa line-stage preamplifier, and remembered that while I'd heard many VAC products at audio shows over the past two decades, and had enjoyed the sound every time, I'd never had a VAC product in my house. I requested a review sample.
