It may surprise some readers to learn that all of the contributors to Stereophile do not get the chance to hear, at our leisure and in familiar circumstances, everything that passes through the magazine's portals. Not that we wouldn't like to, but there just isn't time. Nor are the logistics always right. I was therefore probably as intrigued as the average reader by LA's glowing report on the $5000/pair Mirage M-1 in the June 1989 issue. The M-1s had been on the market long enough for me to have heard them on several occasions, of course, but generally at shows and not under the best of conditions. I did get to hear them briefly at LA's later that same summer, but the hustle and bustle of a Stereophile Writers' Conference party isn't the optimum place for value judgments.

Audiophiles have long had a love-hate relationship with dipolar loudspeakers. These devices are nearly always a pain to position properly, they tend to dominate a room, and more often than not they're fussy about amplification. But when it all comes together, the best of them can make magic.

The concept of a loudspeaker with its own built-in amplification is an idea whose time should long since have come. Technically it makes a lot of sense, and in some parts of the world—not to mention professional circles—it's quite popular. But commercially, the idea has never really taken off in this country. And while the loudspeaker manufacturer should be in a better position to make the best amplifier choice, American audiophiles seem wedded to the idea of making their own amplifier/loudspeaker match.

I should begin this review by confessing that I've never been a fan of subwoofers. Most subwoofer systems I've heard have been plagued by a familiar litany of sonic horrors: poor integration between subwoofer and main speakers, boom, bloat, tubbiness, slowness, excessive LF output, and an overall presentation that constantly reminds the listener he is hearing a big cone moving. To me, subwoofers often sound detached from the music, providing an accompanying thump that bears little relationship to the sound from the main speakers. Rather than revealing the music's harmonic underpinnings, subwoofers often obscure them in a thick morass of featureless boom. In addition, adding a subwoofer often destroys the qualities of the main speakers that made you buy them in the first place—just to name a few of my observations (footnote 1).

Other than that, I like subwoofers.

As one of the founders of Threshold Corporation, its present chairman, and its longtime technical head, Nelson Pass has had a hand in the design and implementation of the products to come out of that company since its inception. His SA-1 power amplifier and FET 10 preamplifier have been long-term favorites of Stereophile founder J. Gordon Holt and I reviewed the Threshold SA-12/e power amplifier a year ago (Vol.13 No.12). I cornered him on a visit to Santa Fe...

Hard to believe it's been more than six years since NHT launched its flagship 3.3 loudspeaker (footnote 1). At the time, the floorstanding 3.3 was a revolutionary product for the company, whose product line until then had been aimed squarely at the customer who wanted good sound, but wanted it in a small, affordable package. While the 3.3 didn't change NHT's dedication to its roots, it did signal to audiophiles that the manufacturer could play ball with the big boys.

When Ken Kantor helped to found Now Hear This, Inc. (most commonly referred to by its initials, NHT) in 1986, he brought with him a wealth of design and production experience learned from stints with NAD and Acoustic Research. He also brought a desire to build and market products that a wide range of people could afford. NHT began by producing small, two-way designs distinguished by the angled front baffle which remains the company's trademark. The latter is no gimmick, but was designed to optimize the loudspeakers' radiation pattern, a matter of keen interest to Kantor ever since his undergraduate thesis work at MIT. This interest continued at AR, where he was responsible for the MGC-1 loudspeaker—probably his best known pre-NHT loudspeaker design.

The letter we received was innocent enough. It asked for our recommendations on laserdisc combination players. You know, the ones that play all of your optical, laser-read entertainment, from CDs to videodiscs. Had the question been a verbal one, our answer would have begun with a long silence. As it was, we could only jot down a few generic references to features, followed by an admission that we had, collectively, no firsthand experience with these all-purpose devices. Only a few members of our staff have any interest in video stuff—monitors, surround-sound, and the like—among them J. Gordon Holt and yours truly.

Déjà vu all over again?

Apart from being reminded of this Yogi-ism by the death, in September 2015, of its originator, I was all set to begin by commenting that this would be my first review for Stereophile of a Paradigm loudspeaker. But—the recent online posting of my June 1992 review of Paradigm's Studio Monitor took me back.

692.parapromo.jpgParadigm is not a new name to US audiophiles, but the Canadian loudspeaker company hopes to increase awareness of its products with their Monitor series, all members of which incorporate a similar design philosophy and drive-units. Heavy and apparently massively constructed, the top-of-the-line Paradigm Studio Monitors ($1899/pair) are the first commercial loudspeakers to pass my way with provision for tri-wiring: three sets of terminals on the back of the enclosures provide direct links to the crossover segments feeding each separate driver (or drivers, in the case of the low end).

Those crossovers use quasi-Butterworth filters, but there is, by design, little attempt to correct for driver aberrations in the crossover, a technique which Paradigm does not believe produces the best results. The wood-veneered cabinet is solidly constructed, making use of a combination of high-density composite hardboard and MDF—a technique claimed to reduce uncontrolled resonances. MDF cross-bracing is provided, and four heavy-duty spikes are furnished per speaker. (I used Tonecones in my listening for the simple reason that three spikes are self-leveling, four are not.)
