LATEST ADDITIONS

I tend to be skeptical of tweaks. Too often in the past, I have heard an astonishingly audible difference when the whatever is demonstrated by its promoter, only for any difference to stubbornly disappear when I try the same thingamabob in my own system. But listening to the difference when Isotek's Bjorn Hegelsted replaced the cheap power strip and stock AC cords in a MoFi Distribution system using the impressive but affordable Wharfedale Diamond 225 speakers ($449/pair) driven by a Quad Artera Play CD player ($2199) and Artera Stereo amplifier ($2299) with a star-wired, 6-outlet Isotek Polaris conditioner ($495) and Isotek Premier AC cords ($149 each), the improvement in image palpability and dimensionality, the elimination of "shoutiness" on female voice, was extraordinary.

Following my keynote speech at the ribbon-cutting ceremony Friday morning, my beat at the Los Angeles Audio Show was the Sheraton Gateway's 1st and 5th floors. Even with just the two floors, this was a daunting prospect—considering that this was the show's debut, it had a larger number of exhibitors than any of us had anticipated. So without further ado, here's the first of my three reports.

The Decca Mark V is the latest version of that English firm's unique "tip-sensing" stereo-matrix-ing pickups. The "matrixing" apellation refers to the fact that the Decca pickups do not use 45°–45° sensing coils, but use instead a combination of vertical and lateral-sensing coils. There is a single coil for lateral sensing, with its pole pieces brought down next to the tip. This is the tip-sensing feature, whose major attribute is that the stylus motions don't have to be conveyed along the length of an armature before reaching the transducing pole pieces. Thus there is virtually no possibility of the stylus vibrations being modified through flexing of the armature prior to their transduction into audio signals.
