Driving the Model Sevens at the 2014 CES were Vandersteen's then-new M7-HPA monoblocks, which provide a high-pass–filtered output (above 100Hz) to the upper-frequency drive-units of the Model Seven. At the time, I made a note to myself that I would like one day to try these amplifiers with the Sevens in my own room. That opportunity came later rather than sooner, after Vandersteen had updated the Model Seven to Mk.II status.

Tomorrow, Saturday April 23, from 4–10pm, JS Audio (4919 St. Elmo Avenue, Bethesda, MD 20814) is hosting a Wilson/dCS/Dan D'Agostino/Audio Research/Nordost event. Wilson's Peter McGrath will be introducing the new Alexx loudspeaker; Dan D'Agostino Master Audio Systems President of Sales, Bill Mckiegan, will be showing the iconic company's new amplifiers; John Quick of dCS will be discussing the latest developments in their Vivaldi (2.0), Rossini, and Debussy ranges; Dave Gordon will be present the new Reference 6 and Reference Phono 3 preamplifiers, along with the New Ref 150 SE amplifier; and Michael Taylor from Nordost will be demming the Odin 2 Reference cables and, it is hoped, he will have the New Valhalla 2 USB Cable for attendees to audition.

I first encountered the work of Dave Wilson in the late 1970s. He was then a recording engineer responsible for some great-sounding records, including pianist Mark P. Wetch's Ragtime Razzmatazz (LP, Wilson Audio W-808), which quickly became one of my favorite system-demo records.

Then Wilson turned his attention to designing loudspeakers. His first model was the Wilson Audio Modular Monitor, reviewed for Stereophile by its then-publisher, Larry Archibald, in August 1983, who described it as "the most enjoyable speaker system I've listened to, and significantly valuable as a diagnostic tool." At $35,000/pair ($83,577 in today's dollars), the WAMM may have been the most expensive speaker then on the market.
