"Grand Integra" is the name Onkyo has given to its line of perfectionist-oriented audio products, and the M-508 is the cheaper of Onkyo's two Grand Integra power amplifiers. (The flagship model is the $4200 M-510, reviewed by Larry Greenhill in Vol.8 No.8, featuring "high current capability," and rated at 300W continuous per channel.)
Most audiophiles know Mobile Fidelity as the record company with the philosophy of resurrecting old, important, recorded performances and re-releasing them with (hopefully) the kind of sound they should have had in the first place. Few audiophiles are aware that Mobile Fidelity is also the name of a (different) recording company which collects sound effects in four channels for motion picture and television post-production.
PSB is a small, Toronto-based manufacturer that has been collaborating with Canada's National Research Council to try and take some of the guesswork, some would say magic, out of loudspeaker design.
The NRC, financed by the Canadian government, does basic research in many technological areas and makes its findings available to any firm wishing to use them. (Most other countries provide or encourage this kind of government/business cooperation. It is against the law in the US, to our great disadvantage.) The NRC's audio division, headed by physicist Dr. Floyd E. Toole, has devoted the last several years to the rather formidable task of defining, and assigning numbers to, the various aspects of loudspeaker performance that affect listeners' subjective assessments of their sound.
While I refuse to admit publicly how long I have been sitting on these loudspeakers before doing the report on them, I must say that it is probably a good thing I wasn't in all that of a hurry to get around to it. They did not sound very good in the room where I had initially installed them, and had I written the report on that basis, it would have been lukewarm, to say the least.
I have now had the opportunity to live with the Acoustat 2+2s in my usual listening room, which is more like a typical listening environment (19' by 24' by 9' and moderately padded), and I am more than a little impressed. This is an extremely good speaker, particularly at its price of $2100/pair.
The 2+2 resembles the Model Four in that it contains four of Acoustat's full-range electrostatic panels per side, but differs from it in that two of the panels (per side) are stacked on top of the first pair to produce a radiating surface twice as high and half as wide as that of the Four. The result, particularly in the case of the black-grilled version we tested, bears a startling resemblance to the mysterious obelisk in 2001, A Space Odyssey. The 2+2 system towers almost to the ceiling (and at just under 8' may be too high for some ceilings), and although it is more graceful in appearance than a pair of Fours, it tends to dominate a listening room at least as much.

If you read my article in these pages about recording the Cumbres and Toltec Scenic Railway steam trains (January 1987, Vol.10 No.1), you may recall the mention of Colossus. Colossus is the name of a new digital recording system which designer Lou Dorren claims to be different from every other digital system in several ways, none of which has ever been disclosed to us. I had a chance to listen to some tapes made on it shortly after writing the C&TSRR article, but since they were made with a completely unfamiliar microphone (Mobile Fidelity Productions of Nevada's own design) and featured mainly the sounds of trains, airplanes, and other sources of potential ear damage, I couldn't really tell anything about the recording system, except that it had the kind of low end I expect from any respectable digital audio. A sonic evaluation had to wait until I heard Colossus on more familiar termsthat is, with music recordings. Now, that time has come.
It is often said that anyone with a recorder and a couple of microphones can record an orchestra. It's true, assuming you can get permission to do it (another story entirely). But that statement fails to address an important question: "How well?"
The rudiments of any skill can be learned from books. Practice can develop a fair level of competence. Beyond competence, however, the student is governed by his genes and/or family environment, depending on which theory of human potential you subscribe to. Whatever the reason, some practitioners of both disciplines never seem able to transcend mere competence, while others go on to become legends in their own times. John Eargle, chief recording engineer for Delos Records and producer of this fascinating recording, may or may not qualify as a legend, but he is obviously 'way past "a fair level of competence."
A very popular myth among the audio unwashedand one still perpetuated by the pop hi-fi writersis that nothing is to be gained by paying more than $1000 for a stereo system (footnote 1). Members of the general public, including masses of people who enjoy live, unamplified music, have the impression that more money simply buys one wider and wider frequency range, and defend their $500 "compact" systems with the lame excuse that their ears aren't all that good, and who needs to hear what bats hear anyway? This is no doubt a soothing emollient for one's disinclination to invest more money in audio gear, but it is a supreme self-deception.
Klyne Audio Arts is such a low-profile outfit that I marvel at its continued existence. It is reliably absent from the Audio and Stereo Review annual equipment directories, and if Stan Klyne has ever run an advertisement for any of his products anywhere, I haven't seen it, Yet Klyne Audio Arts always manages to have an exhibit at CES, where they display some of the most beautiful preamps and head-amps we see there, only to go underground again for another six months.
Although the idea of a $1000 moving-coil cartridge no longer shocks audiophiles, it is still not exactly what I'd call "Mainstream Hi-Fi." Audio magazine's 1984 Equipment Directorythe most complete such compendium published in the USlists only 10 models in this price range, not counting the Kiseki Lapis Lazuli at a whopping three-and-a-half grand! I have not tested most of these, nor have I tried any of the current models from the Japanese Koetsu firm, which was first with the gall to put a $1000 price tag on a cartridge. But I have tested a couple of one-granders during the past few years, and was sufficiently unimpressed to be hesitant about testing any more samples of what were beginning to look like nothing more than monumental ripoffs. So when Ortofon sent us the MC-2000, I was naturally less than enthusiastic about trying it.

The American computer industry was a little shaken up to learn recently that the Japanese micro manufacturers had gotten together and standardized their component interconnections so that any Japanese computer will (supposedly) plug into any Japanese printer, modem, or competing computer, and work right off the bat. Anybody who has tried to fire up an Apple computer with a Diablo (Xerox) printer will appreciate what the Japanese move means in terms of compatibility. It means "For no-hassle interconnections, buy Japanese."
Now that audio technology seems to be on the verge of being able to do anything asked of it, it seems only fitting to wonder about what we should be asking it to do. We probably all agree that high fidelity should yield a felicitous reproduction of music, but felicitous to what? Should a system give an accurate replica of what is on the disc, or of the original musical sounds?
There was a time, very recently in terms of human history, when high fidelity promised to free the music lover from the constraints of the concert hall and the local repertoire, allowing him to choose at his whim any orchestra in the world playing any work he desired under the baton of any conductor he preferred. "All the pleasure of concert-hall listening, in the comfort of your home," was the way one display advertisement painted this musical utopia which, only 20 years ago, seemed right around the corner.
