Way back in the mists of time, around 1980 to be exact, the Marantz company in Europe introduces a range of ostensibly cost-no-object solid-state electronics under the "Esotec" banner. Manufactured in Japan, but apparently designed in the USA, these ruggedly constructed components are noteworthy in that the power amplifiers are capable of being operated with the output stages running under class-A bias as well as class-B. The relatively expensive Esotec amplifiers sell in small numbers in the UK—remember that this is before the rebirth of the British high end—and pass into the history books. I am reminded of them, however, when I visit my friend Ivor Humphreys of Gramophone magazine at Christmas 1987; he is using a pair of the 30W mono class-A Marantz amplifiers to drive KEF R107s—and making very nice sounds.

Welcome back, Ladies and Gentlemen, to the continuing saga of the Englishman's Search for True Bass. In the previous episode (footnote 1), you witnessed Our Hero tussling with the problems of ported vs sealed-box woofer loading for full-range speaker systems. His conclusion? That ported designs may offer low-frequency quantity but it always seems to be at the expense of quality. If it's bass quality you want, you are better off with well-tuned sealed boxes, which explains why he is an unashamed fan of relatively small speakers with fast, tight upper bass. In this month's thrilling installment, JA—stiff upper lip thrust forward—wrestles with the problems of extending the bass response of his preferred speakers with a subwoofer from the Californian company of Sumo! Now read on . . .

Elsewhere in this issue, I review the new Spica Angelus loudspeaker, only the fourth product to appear from this Santa Fe-based manufacturer since it started operations at the end of the 1970s. You will have to read the review to learn what I thought of the speaker, a distinctively styled floor-standing two-way, but I also thought it would be beneficial to talk with Spica's founder and chief engineer John Bau. I therefore made arrangements to meet with him in their facility just a couple of blocks from Stereophile's old Early Street HQ. I had been told that John was tall, but until he unfolded himself from his stool in his laboratory, surrounded by computers and computerized test equipment, I had not realized how tall! Undaunted, I settled into a conventional chair, pointed the microphone in a vaguely upward direction, and asked John how he had gotten into loudspeaker design.—John Atkinson

I am puzzled. No, really. I know you find it hard to believe that we sacerdotes of the golden-eared persuasion could ever be perplexed, but I have been pondering the imponderables of ports. Ever since the classic work of Richard Small and Neville Thiele in the early '70s showed how the low-frequency response of any box loudspeaker can be modeled as an electrical high-pass filter of some kind, with the relevant equations and data made available to all, there would seem to be very little reason why all loudspeakers with the same extension should not sound alike (or at least very similar) below 100Hz. Yet after reviewing 20 dynamic loudspeakers (and using 24) in the same room over the last seven months, I am led to the conclusion that speakers vary as much in the quality of their mid-to-upper bass as they do in any other region. A few are dry, more are exaggerated in this region; some are detailed and "fast," most are blurred, with the upper bass "slow" (by which I mean that the weight of bass tone seems to lag behind the leading edges of the sound).

So far, as part of my quest to find good affordable box loudspeakers, I have reviewed 16 models, in the August, October, and November 1987 issues of Stereophile (Vol.10 Nos.5, 7, & 8). This fourth group of loudspeakers expands the price range covered, down to $329/pair and up to $1349/pair, and includes one model from California (Nelson-Reed), one from Canada (Paradigm), and one, Monitor Audio's "flagship," the R952MD, from the UK.

Someone, I forget who it was, once wrote a perceptive essay on how in any field of human endeavor, apparent perfection is attained only when that field is in the process of being superseded. The Palace at Versailles was built when the power of the French monarchy was well into decline; Wagner's "music of the future" was in fact the end of a particular line of development; the nuvistor was developed almost simultaneously with the silicon transistor which would render tubes almost obsolete; and six years after the commercial introduction of Compact Disc, with record shops increasingly filling up with silver discs, to the detriment of black, turntables exist which render LP playback pretty much on a level with CD technically (many audiophiles, of course, feel that the LP has always been musically ahead).

Scene the First. You are sitting in a concert hall, dead center, row M; the cellist walks on to the stage, sits down and starts to play the prelude to the first of Bach's solo cello suites, that intricate unfolding of a rhapsodic melodic line within the tight framework of an implied chordal structure. Melody, harmony, rhythm—none exist at any one point of time in this most exquisite of Bach's solo instrumental writing, yet the skill of the composer, coupled with the artistry of the musician, allow you to perceive the abstract as reality.

1087azima.jpgIn its first three years, UK hi-fi manufacturer Mission Electronics employed a number of engineers to reinforce the creative talents of founder and hi-fi enthusiast Farad Azima. The lineup included John Bicht, now with Versa Dynamics, and Stan Curtis, now heading up Cambridge Audio. But when Farad's brother Henry—"Henry" is actually a nickname and I am sure you can see the derivation—joined the company in 1979, he brought both a much-needed stability, and initiated a considerable degree of commercial success for the company's products. Now resident in Canada, he spends his time commuting between his laboratory in Toronto and the company's headquarters near Cambridge, England (footnote 1). Prior to joining Mission, however, Henry had served in the Iranian Navy for 15 years, an unusual training for an audio engineer. I asked him if this had been an appropriate preparation for the world of hi-fi.

Henry Azima: I had actually been a student in the UK, studying electronic engineering at the University of Surrey in Guildford. When I left the Navy in 1979 after the revolution in Iran, I moved to the UK and got a job with my previous University as an Assistant Lecturer and Researcher. However, Farad then asked me out of the blue to join Mission. I said, "Well, I have no idea about hi-fi, and stuff like that." He said, "You will learn, there's no problem!"

Since its founding just over ten years ago, Mission Electronics has grown to become one of the largest "real" hi-fi companies in the UK. Although their product line originally consisted of three relatively conventional loudspeakers, it rapidly grew to encompass high-end pre- and power amplifiers, cartridges, tonearms, and turntables, and, in the mid 1980s, a system concept based on CD replay and relatively inexpensive electronics: the Cyrus amplifiers and tuner.

Some six or so years ago, the Linn Asak cartridge set new standards for imaging and soundstage reproduction. I can remember the first time I heard an Asak in a system using Quad ESL-63s—I had never experienced such depth of soundstage and solidity of imaging from any system, and that with Quad amplification! The Asak was relatively quickly overshadowed in this area, however, and in any case, soundstaging precision by itself didn't seem to be a high priority for the Linn design team, who were apparently more concerned with dynamics and a musical integration of the sound across the frequency range.
