I was so impressed by the Nelson-Reed 8-04/B loudspeaker's low-end range that I seriously doubted the add-on subwoofers could add enough of significance to be cost-effective.

I was wrong.

Two of the subwoofers were provided, along with the necessary electronic crossover unit. Each 1204 unit contains four 12" woofers in a very solid sealed enclosure, with two facing to the front and two facing the rear. The electronic crossover has three controls, besides the AC power switch: a hardwire (footnote 1) bypass switch, a stereo/mono switch, and a subwoofer level control. In the stereo mode, the low frequencies are kept separate, left from right; in mono mode, they are blended together for feeding to a single subwoofer. I will not resurrect the question of whether or not it is important to maintain stereo separation into the LF range, except to echo N-R's observation that there is no LF separation on analog discs to begin with; the lows are mixed together, to limit vertical excursions of the cutting stylus that could cause it to rise above the disc surface or, worse, dig into the aluminum base of the master disc.

Nelson-Reed 8-04/B loudspeaker

According to designer Bill Reed, the Nelson-Reed 8-04/B was not originally intended to be an audiophile speaker system, but was instead designed as a high-quality monitor for the critical recording engineer who wanted to be able to walk from the studio into the control room and hear the same thing from his speakers that he heard "live." The fact that modern studio mike technique ensures that this could never happen is probably beside the point. The point is that reproducing the original power and dynamic range of live music is a formidable challenge, which practically no audiophile speakers have met successfully. On the other hand, so-called studio monitors, which can do that routinely, have tended to be highly colored and otherwise generally lousy in all areas of fidelity except output capability. The 8-04/B was an attempt to combine the strengths of both kinds of speaker, while avoiding their usual weaknesses.

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.

Observations and Prognostications for 1965

Well, the New York Hi-Fi wingding has come and gone once again, and now is the time when audio editors dutifully adopt the role of oracle, divining the future of high fidelity, and generally sketching out The Big Picture for those of us too blind to see the graffiti on the wall. So, who are we to shirk our duty? Herewith, The Stereophile's audio observations and predictions for 1965.

We have still not received a pair of these for formal testing, which may be a good thing in view of our feelings these days about "updatings." (Our feelings about such are clarified in this issue's "As We See It.")

Onkyo Grand Integra M-508 power amplifier

"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.)

Ortofon M15 Super phono cartridge

J. Gordon Holt | Jun 01, 2017 | First Published: May 01, 1974 | 4 comments

The M15 Super is the first high-output pickup to come from Ortofon. Previous ones required either step-up transformers or a booster preamp, and it is only fairly recently that either kind of step-up device was available with high-enough quality to avoid a noticeable degradation of the sound. Early step-up transformers muddied the bass, and previously-available booster preamps added noise or hardness or both to the sound. Now that there are excellent transformers available from Ortofon and other sources, and at least one extraordinarily good booster preamp (the Mark Levinson, at an extraordinarily high price—$170), Ortofon's latest and best pickup doesn't require the use of either.

Ortofon MC-2000 MC phono cartridge

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 Directory—the most complete such compendium published in the US—lists 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.

Ortofon MC-3000 MC phono cartridge

The Ortofon MC-2000 may just have been the most impractical cartridge to be unleashed upon the audio community for some years. With a high compliance (20cu) that made it ill-suited for most tonearms, it also had a preposterously low signal output of 50 microvolts, which gave new meaning to the terms hum and noise. Few MC preamps had enough gain to deliver adequate driving voltage to a system, and none of those that did had low enough noise to be usable with the 2000. If the problem wasn't hum, it was hiss; if hiss was acceptably low, there would be too much hum. At least Ortofon had the sense to be aware of the problem and to do something about it, in the form of their T-2000 step-up transformer, which is the only device I ever found that would allow the cartridge to be operated without a constant background of hum or hiss. Despite all this, I have used the MC-2000 as my reference cartridge for the last two years. Why? Because of all the cartridges I've tried, it is by far the most accurate.

Ortofon RS-212 tonearm

J. Gordon Holt Tonearm Reviews

J. Gordon Holt, John Wright | May 09, 2017 | First Published: Feb 01, 1968 | 1 comments

The RS-212 is one of the most impressive-looking tonearms we've seen in many a moon. Our first reaction to it, in fact, was much the same as our reaction to the first big, professional Ampex tape recorder we ever saw: it reminded us of one of those precision-engineered and cleanly styled electronic devices you see in hospitals and industrial laboratories—devices which make no attempt to cater to the current fashion in interior decorating or depth-researched consumer preferences, but which are designed simply to do a job neatly and efficiently. This arm, in short, is practically guaranteed to impress your Magnavox-oriented friends with the quality of your phono system, no matter how oblivious they may be to its actual sound.
