Perfectionist Audio Components CPR IIIB/TIPS preamplifier AC/DC

Sidebar 1: AC/DC

Item: AC power-line conditioners have become a major audio product category, featured in "Recommended Components" and used by several Stereophile reviewers—including RH, JE, JA, GL, CG, and RD—in their own systems.

Item: British rep for Audio Alchemy finds that their D/A processor takes too long to warm up for convenient demonstration when he takes it to dealers. His solution is to build a battery-operated power supply, using a car battery, so that the D/A processor can be kept powered up while traveling. He then notices that the processor sounds better with the makeshift battery-operated power supply than with the regular AC supply. (HFN/RR, April 1992)

Item: At the Los Angeles Stereophile Show, MSB Technology introduces the MSB Portable Power Plant ($2999), providing AC-DC-AC conversion using batteries. The product literature states: "The difference is amazing."

Item: At the 1992 Chicago CES, the Jeff Rowland Design Group announces the availability of a battery-operated power supply for the Models 8 and 9 amplifiers.

Item: At the recent Stereophile Writers' Conference, Arnis Balgalvis talks about how musically involving it can be to hear music on a car radio. John Atkinson suggests that "there may be something that car radios do right in general that sophisticated high-end systems do wrong." ("As Reviewers See It," Vol.14 No.12, p.27.) Be it noted that car radios are battery-powered.

Is there a pattern here? What about the proliferation of cordless (ie, battery-operated) electric shavers, drills, hedge trimmers, etc.? Have you ever seen an electric eel with a cord attached? I think I'll put my money in the battery business.—Robert Deutsch
