95christie.250.jpgWhen Cary Christie, Arnie Nudell, and John Ulrick founded Infinity Systems more than 25 years ago, high-end audio as we know it today didn't exist. Hi-fi was audio, though the reverse wasn't necessarily true.

Through the growth years, Infinity became a major force in the High End. Cary Christie is the only one of the original players still associated with Infinity in 1995, now part of Harman International. His relationship, however, is now as an independent designer and consultant with Christie Designs, Inc. (footnote 1). I corralled him by phone on a clear fall day in Santa Fe, and a snowy one at his home near Lake Tahoe, Nevada. I asked him how Infinity had started.

The DQ-12 is the latest loudspeaker from Dahlquist employing their "Phased Array" technology, first used in 1973. The company was formed that year by Jon Dahlquist and Saul Marantz to produce the DQ-10, a loudspeaker that enjoyed a long and successful life. When I sold hi-fi in a retail store in the late 1970s—we stocked Dahlquist speakers—the DQ-10 was among the more prominent audiophile speakers, prized for its imaging abilities.

In 1976, Carl Marchisotto joined the company, designing support products for the DQ-10 including a subwoofer, variable low-pass filter, and a passive crossover. Jon Dahlquist is no longer actively involved with the company; Carl has now assumed the engineering responsibilities at Dahlquist and is the designer of the latest group of Phased Array loudspeakers (footnote 1). This new line, introduced at the Winter 1990 CES in Las Vegas, encompasses three models: the $850/pair DQ-8, the DQ-12 reviewed here, and the $2000/pair flagship, the DQ-20i.

In the October 1994 Stereophile (Vol.17 No.10, p.39), I discussed my experiences with the DTS audio data-reduction code/decode switch box, which, briefly, is a two-channel box that makes use of the algorithm DTS has proposed for their version of discrete multichannel sound for laserdiscs.

When we reviewed Pioneer's flagship Elite DV-09 DVD player in our September 1998 issue, it blew us away so much that it garnered an Editors' Choice award (see the February 1999 issue) as the best DVD player we had reviewed up to that time. This opinion has not changed in the intervening months, but at $2000, the DV-09 is more than many home-theater fans can afford (or justify) for a DVD player. The Elite DV-05, introduced earlier this year, provides many of the features and most of performance capabilities of the DV-09 at a more affordable price.

The new DV-09 is Pioneer's first DVD player in its Elite line. More than simply an upscale version of a standard Pioneer DVD player, the DV-09 was built from the ground up to be a flagship product. It's also the first DVD player I've seen to have been certified under THX's DVD-player certification program (see sidebar, "THX DVD Players").

Reality check number one. Tired of reading about the latest and greatest $65,000 loudspeakers? Or even the current hot ticket at $2500? Such loudspeakers promise to bring you the audio truth, or the golly-gee-whiz, honest-to-gosh, absolutely positively real sound. And some of them do seem to come awfully close, though truth be told, we're still a long way from replicating reality—and will never do it with just two channels.

If Canada has emerged as a hotbed of loudspeaker production in the past few years, the folks at Audio Products International must be positively sizzling. Of their three lines—Mirage, Energy, and Sound Dynamics—Mirage is perhaps the best known in the US, with Energy running a distant second. Mirage, at least in their flagship M series, features rather esoteric bipolar designs, while Energy sticks to the more conservative, forward-radiating approach. Stereophile has had extensive exposure to the various Mirages (a review of one of the M-series babies, the M-7si, is scheduled for a future issue); our exposure to Energy has been virtually nil, save for the odd Hi-Fi Show and CES. And thereby hangs a tale.

Room acoustics, and their importance, may not be subjects which we ponder daily here at Stereophile, but they are never far from our consciousness. Two recent events served to spotlight them yet again: the setting-up of our first-ever panel listening test of moderately priced loudspeakers (Vol.14 No.7), and a letter from a reader requesting advice on room problems. Both reminded us---if a reminder was needed---that although the perfect room does not exist, there are things that can be done to make the most of even an admittedly difficult situation. That reader's letter, in particular, brought home the fact that we cannot really discuss this subject too often. It's easy to forget that comments made here months (or years) ago are beyond the experience of newer readers. A new audiophile's most frequent mistake is to overlook the significance of his or her listening room, while the experienced listener will too often take the room for granted.

Americans might be forgiven if they haven't heard of Epos. A small, British specialist loudspeaker manufacturer, it was founded in 1983 by its designer, Robin Marshall—an ex-BBC engineer and a onetime consultant to Monitor Audio, according to Roy Hall of Epos's US importer, Music Hall. Their first model, the ES 20, didn't make it to the US, and was apparently a bit too pricey in the UK to make much of a splash there (about £700, $1300 at the current rate of exchange—a mint in a country with the patent on sub-$500/pair (UK prices!) two-ways). In 1986 or thereabouts, the new, smaller ES 14 was introduced, using updated versions of the same drivers in a smaller, ported cabinet. Music Hall only recently began importing the Epos into the US.
