The idea of a loudspeaker system whose frequency response could be tailored to suit room acoustics and/or personal taste is one that has always appealed to the high-fidelity perfectionist. Ideally, such a loudspeaker would allow you to raise or lower the level of any part of the audio spectrum to correct for, say, a sharp 370Hz room resonance or a mild absorptive condition that weakens, say, the 800Hz–3kHz range. Obviously, though, this kind of flexibility would require an infinite number of bandpass networks, each with its own volume control—which is an obvious impracticality.

By the time you read this, in the fall of 1967, the "Dolby system" will probably be old hat to you. Every other audio publication has been describing it, discussing it, and hailing it as the greatest invention since sex.

We've seen that kind of press ballyhoo before, about such significant advances as the Edsel, the 16-rpm LP and the "thin-profile" loudspeaker, so our first inclination was to be a wee bit skeptical of the Dolby. It seemed too good to be true.

It is not at all unusual these days to find manufacturers producing "matched" speakers and amplifiers that are designed specifically for one another. But it is very unusual to find this being done by an amplifier manufacturer who doesn't make loudspeakers. The Futterman H3-A is one of these rarities—an amplifier designed primarily to complement one of the best, and one of the hardest-to-drive loudspeakers on the market: the KLH Model Nine.

Back in the days of pre-stereo high fidelity, when a 6-gram phono pickup was considered to be "featherweight," the best universal-type tonearm we knew of was a bulky, very professional-looking device made by Gray Labs and designated the Model 108. One unusual thing about it was that, instead of using sleeve or cone-face bearings, it had a single up-ended needle—a so-called unipivot—for both the vertical and lateral modes of motion. The other unusual thing about it was that the pivot system was viscous-damped, and it was this, we suspect, that was largely responsible for the arm's ability to make any pickup sound somehow sweeter and cleaner than it did in any other arm.

Editor's Note: in the main, Stereophile has steered clear of DIY audio projects, leaving them to magazines like The Audio Amateur, which was published by the late Edward T. Dell. But one of the exceptions was this 1967 article on the "Brute," a tube amplifier design by none other than Ed Dell. Note that the DIY competition mentioned by Gordon Holt is long closed to entries.—John Atkinson

There's a platitude to the effect that the road to Hell is strewn with good intentions. Well, we don't see ourselves as headed for perdition, but we must admit that we are surveying a rather impressive-looking junk pile of good intentions at this point.

An Audio Obstacle Course: The Shure Trackability Test Record
Shure Bros. TTR-101.

Shure's new "Supertrack" V-15 Type II pickup was designed as an answer to all those high-powered discs whose excessive modulations make them shatter all over the place on lesser pickups, But just in case anyone didn't happen to own any of these difficult discs, Shure decided to issue one of these, too. The result is a collection of some of the meanest modulations ever gathered together in one place.

When we first heard rumors that Shure Brothers was about to unleash something called "trackability" on the audio world, our reaction was mainly one of indifference. We already had loudspeakers with listenability, tape recorders with portability, and amplifiers with stability and dependability. Trackability, we figured, was just another clever sales gimmick; a catchy word that the advertising department had thought up to describe what everyone wanted in a pickup.

Tchaikovsky: Swan Lake & Sleeping Beauty Selections
New Philharmonia Orchestra, Stokowsky
London Phase-4 SPC 21008 (LP); Ampex LCL-75008 (open-reel tape). Tony D'Amato, Marty Wargo, prods.; Arthur Lilley, eng. TT: 46:50.

These are exciting, lilting, concert-style (as opposed to ballet-style) performances of the best-known excerpts from Tchaikovsky's second- and third-most-popular ballets. (First, of course, is the Nutcracker.) The recording is a surprise, after the excesses we've heard on earlier Phase-4 recordings.

This is an integrated arm-and-turntable unit using single-belt drive from a stepped motor pulley to an inside platter (under the main one), and having a three-point suspension similar to that in the AR turntable for isolation from acoustic feedback and floorborne vibrations. Speed change is accomplished by a two-pronged "fork" which, actuated by the speed selector knob, throws the belt from one step of the motor pulley to the other. The motor is a special synchronous type that is actually two motors in a single case. Their speed is determined by the frequency of the AC supply, so there is no speed adjustment.

The Z-600 is the latest of the "console" (as opposed to "bookshelf") systems made by Neshaminy Corp., and using Janszen electrostatic tweeters (footnote 1) and a Neshaminy-designed 11" woofer. The nominal crossover frequency is 1500Hz, with a broad overlap between the woofer's top and the low end of the paralleled tweeters. Tweeter level is not adjustable (footnote 2).

Our mail, in recent months, has brought a number of comments (some of them printed in this issue) from professional audio men who decry the fact that developments in the audio field seem to have come to a screeching halt.

There would seem to be some justification for believing this, too. There hasn't been a new kind of loudspeaker, amplifier, pickup, or tuner for the past five years or so. The professional engineering journals, once loaded with juicy articles about research and developments in music reproduction, are now devoted largely to public-address techniques and new methods for the "creation" of electronic music.

Sibelius: Symphonies Nos.4 & 5, The Swan of Tuonela, Tapiola
Berlin Philharmonic, Herbert von Karajan
Deutsche-Grammophon 138 974 (LP, Symphony 4). Both symphonies reissued on CD (Deutsche Grammophon 457 748 2)

Magnificent, musically natural recordings with some of the deepest, fattest bass and richest, warmest orchestral sound that's been committed to recordings for many years. The discs are a shade more lucid than the tapes, but not much. Take your pick.—J. Gordon Holt

One by one, the major amplifier manufacturers have acceded to the pressures of the marketplace and introduced "solid-state" models, whether or not these happened to sound as good as their previous tube-type units. Dynaco was one of the last of the hold outs, preferring, according to their advertisements, to wait until they could produce a solid-state unit that was at least as good as their best tube types. Now, they've taken the plunge at last, with their Stereo 120.

One of the most firmly-established audio platitudes is the one which says "The specs don't tell the whole story." One reason for this, of course, is the fact that most manufacturers, preferring to sell their products on the basis of emotional appeals in ads rather than on hard, cold performance claims, do not attempt to make their specs tell the whole story.

Editor's Note: Although this product has been available for several years, it is being reviewed in considerable detail because it is a strong contender for the title of "Best Available Loudspeaker System, Regardless of Cost," and because we plan to review some of the other contenders for the same title within the next few issues. We feel that since all of these systems represent a considerable outlay of money, prospective buyers should have a thorough understanding of the merits and demerits of each system, so they will know what to expect from them in the way of performyince capabilities and operational requirements.
