Audio Power Industries Power Wedge 1 AC line conditioner ($499; reviewed by Corey Greenberg, Vol.14 No.11, November 1991)

Again I smiled when I counted up the votes in this category. The winner was a product, the kind of which didn't even exist just a few years ago. The conventional wisdom, at least in domestic systems, used to be that a component's power supply offered an insuperable barrier to the slings and arrows of outrageous AC line glitches and garbage. In these more pragmatic days, we accept the fact that AC power is as grundge-ridden as our industrial…

When we conceived our annual awards, the "Editor's Choice" idea surfaced as a way of recognizing products that have stood the test of time. An aspect of this industry…

Spica SC-30 loudspeaker ($399/pair plus stands; reviewed in Vol.15 No.5, May 1992)

Look at the Spica, and you see nothing out of the ordinary for a cheap loudspeaker. A paper-cone woofer—why, it even uses a cone tweeter, like some junk speaker from a radio hut. But used on a pair of good stands—which admittedly will add at least half as much to the price—the SC-30's sound is richly balanced, with good bass and treble extension, excellent clarity, and pretty good soundstaging. Sure, there's a "woody" quality to the lower midrange, and the mid-treble is a…

Mark Levinson No.30 D/A processor

There were five deserving contenders for the crown, but the result was never in doubt. Expensive it may be, but the Mark Levinson No.30 typifies what Stereophile's "Product of the Year" is all about: superb sound quality coupled with inspired engineering, resulting in a component that will be regarded as a true Reference. If I could afford a No.30, I'd buy one tomorrow (footnote 2). But even though I can't afford one, it makes me feel good to know that something this well-engineered exists, raising digital…

"'Happy' is our primary product," Elliot Fishkin, the proprietor of Innovative Audio, which is entering its 45th year of business, told visitors early Thursday evening, January 21. "We want you to be able to be connected to the music in profound ways." A small crowd was gathered in the lobby outside Innovative's newly renovated showrooms, in an expansive underground space on the east side of Manhattan, to hear amplifiers by VTL, cables by Transparent, and loudspeakers by Wilson Audio.

The evening's guests included Luke and Bea Manley of VTL, Transparent's Josh…

At $480/pair, the Model 1.3 is midway in NHT's product line. Finished in a gloss-black high-pressure laminate, the 1.3 is elegant, even beautiful, and is distinguished by its unusual angled front baffle.…

I drove the Model 1.3s with a sinewave oscillator with my hand on the cabinet to detect resonances. They exhibited very few resonances, the loudest being at 140Hz and 330Hz. The 140Hz resonance produced a buzz, but was not as severe as the Tannoy E11's 220Hz peak.

The 1.3's impedance (fig.1) was lower than those of the Dana Model 1 or E11, at about 6 ohms through most of the low- to mid-frequency band. The narrow impedance peak at 66Hz reveals the 1.3's sealed-enclosure design. The Model 1.3's impulse response is very clean, with a minimum of ringing (fig.…

The NHT loudspeakers were auditioned in my dedicated listening room with the following ancillary equipment: VTL 225W Deluxe monoblock power amplifiers, Esoteric D-10 and D-2 digital processors, a Theta DSPro Basic digital processor, and the Electronic Visionary Systems Stepped Attenuator, a passive control unit. The analog front end was a VPI HW-19 Jr. turntable with an AudioQuest PT-5 tonearm and Sumiko Boron cartridge. A new outboard phono preamp made by Precision Audio allowed me to use the passive control unit for both CD and LP playback.

Not so in Tokyo, where commuters, tourists, and shoppers moving through the Shinjuku or Shibuya subway stations will find it almost impossible to ignore Sony's latest advertising campaign, which colorfully announces a new range of affordable portable audio players (né Walkmans). Inside, banners suspended from the cars' ceilings promote Panasonic's latest headphones and shoebox-sized stereo system. Many of the bigger…
