This business biography of hi-fi pioneer Gilbert Briggs and his company, Wharfedale, is an exhaustively researched labor of love on the part of his grand-nephew David Briggs. In a sense, the book is a prequel to Ken Kessler's KEF: 50 Years of Innovation in Sound (2011). That's because KEF's founder, Raymond Cooke, worked for Gilbert Briggs at Wharfedale from the early 1950s through mid-1961. But that is getting ahead of ourselves.

In a recent Stereophile.com news item, John Marks informed readers about free online music production classes now offered from the esteemed Berklee College of Music. Seems like JM himself is taking up this opportunity. In this video assigment, JM shares his explanation of the ORTF microphone placement technique for stereo recording.

It was the strangest thing. In the fall of 2008 I was comparing Ayre Acoustics' then-new KX-R line preamplifier with no preamplifier at all—I was feeding the power amplifier directly with the output of the Logitech Transporter D/A processor. (Levels were matched for the comparisons, of course, made possible by the fact that the Transporter has a digital-domain volume control.) Being a rational being, I knew that the active circuitry of a preamplifier, as well as the extra socketry and cables, would be less transparent to the audio signal than a single piece of wire. I wanted to determine by how much the Ayre preamp fell short of that standard.
