Music lovers worldwide are mourning the passing of violinist Isaac Stern, who died of heart failure in a New York hospital Saturday, September 22. Stern was 81.

Bringing old albums out of the vaults and onto the market as CDs is a pretty standard process these days. First you get the licensing straightened out, find the original cover art, and locate the first-generation master tapes. In a pinch, the safety copies of the masters can be used, but if these also can't be located, what next?

The terrorist attack of September 11 will likely worsen an already dark period for American retailers. The Dow Jones Industrial Average declined by more than 14% in the week after the attack, the largest slide since the week of July 21, 1933.

Last month I wrote about lasers of various pedigrees, so useful in marking walls to the sides and behind the listening position to ensure that your loudspeakers are toed-in, level, and equidistant from the sweet spot for best soundstage, imaging and focus. Using small Avery stick-'em labels makes this a snap. I've converged the tweeter axes of my JMlab Utopias somewhere about a foot into the wall behind the rearmost of our two listening chairs, and use two Studio Traps and a single Argent RoomLens between the speakers to cancel and damp the near-rear-wall reflections. With just a jiggle of the chair back or forward, suddenly I'm there.
