It says something for the state of technology that, after a quarter of a century, there still is no authoritative explanation for why so many high-end audiophiles prefer tubes. Tubes not only refuse to die, they seem to be Coming back. The number of US and British firms making high-end tube equipment is growing steadily, and an increasing number of comparatively low-priced units are becoming available. There is a large market in renovated or used tube equipment—I must confess to owning a converted McIntosh MR-71 tuner—and there are even some indications that tube manufacturers are improving their reliability, although getting good tubes remains a problem.

Many audiophiles who have only recently subscribed to Stereophile will be surprised to find that those clunky, heat-producing, short-lived tubes that reigned up through the mid-'60s are still Executive Monarchs in the mid-'80s. Why, for Heaven's sake? Because, despite everything, people like them.

Whenever an audio high-ender thinks about tubes, he usually thinks about Audio Research. This is only natural, because Audio Research Corporation was almost single-handedly responsible for saving tubes from oblivion in the early '70s when everyone else switched to solid-state. But ARC was soon joined in its heroic endeavor by an upstart company called Conrad-Johnson, which entered the fray in 1977 with its PV-1 preamp, priced at an affordable (even then) $500.

The $1485 PV-5 is a "budget" version of C-J's $2850 Premier Three preamplifier, but according to the manufacturer it embodies much the same kind of circuitry.

Tubed preamplifiers have a well-earned reputation as system busters. Many of them during warmup produce horrendous bangs or plops so severe that every speaker fuse in the system blows. If fuses are absent, or rated too high to protect things, the amplifier, speakers, or both are likely to blow up (not literally; they just twitch once and lie down dead). The PV-5 contains one of the most effective pop suppressors I've encountered, and produces no noise whatsoever during warmups and turnoffs.

The issue is this business of "single-speaker" listening and demonstration, which has become fashionable in the UK.

The premise: bringing a second pair of loudspeakers into your auditioning room upsets the sound of the pair you're listening so badly that the first speaker's ability to correctly reproduce the timbre of musical instruments is destroyed. This observation is almost surely correct.

Now that Sony has bought CBS's records division, and the infamous Copycode bill seems to be dying in Congress, the way may be clearing at last for the US introduction of the new Digital Audio Tape system. This has sparked renewed speculation in the industry about the impact DAT will have on existing formats, particularly the fledgling CD. Some are convinced DAT will kill CD, because of its ability to record as well as play digital recordings. Others believe DAT won't even gain a foothold in the market, for the same reason quadraphonic sound laid an egg back in the '70s: The public can't handle more than one "standard" format. I feel that both views are wrong, and that—as is usually the case with extreme views—the truth lies in between. I believe DAT will catch on in the marketplace, but never in a big way, and certainly not the way CD has. Here's why.

How can you tell when a politician is lying? His lips move. How can you tell when a recording system is perfect? CBS tries to outlaw it.

To audiophiles who are aware that their household line voltage changes under varying loads, and have observed the absolutely fantastic differences in the sound of their system when the next-door neighbor turns on Junior's night light, it may come as a surprise to learn that there are folks out there who think you're full of crap. That's right, Virginia, they don't think you can really hear all those things you pretend to hear. (You are only pretending, aren't you?) They can't hear all those things, so how can you? Well, sometimes they can. They'll even admit that. But those tiny little differences are so trivial that they don't matter no more than a fruitfly's fart. That's the word in scientific circles these days. Or haven't you been following the "establishment" audio press lately?

If we had been asked some time ago to describe our "dream amplifier," chances are we would have described the Crown DC-300. Designed originally as an industrial device, it was made available as an audio amplifier rather as an afterthought. But if that roundabout approach is necessary to produce an audio amplifier like this, so be it.

The Dalhquist DQ-10 loudspeaker has not as yet been formally submitted for review. (The designer tells us he is still working on the low end.) We auditioned a pair at the one local dealer we could find who had the DQ-10s on demo, and were immensely impressed. Obviously, Jon Dahlquist is on to something that other speaker designers have been overlooking, for, despite the multiplicity of driver speakers in the system, the DQ-10 sounds like one big speaker. There is no awareness of crossovers or separate drivers (except at the low end, about which more subsequently), and the overall sound has a degree of focus and coherence that is surpassed only by the Quad full-range electrostatic, which don't go as low at the bottom or as far out at the top.

Although most audio perfectionists look down with scorn on equalizers, there are times when the benefits of such devices can outweigh their disadvantages. I discussed the pros and cons in my review of the Accuphase G-18 in Vol.11 No.4, but a brief recap here won't be amiss.

The unsung sage who first observed that high-end audio is a solitary vice was probably not implying that audiophiles are antisocial; he was merely acknowledging the fact that a decent stereo stage is usually only audible from one place in the entire listening room—the so-called sweet spot. Stray from that spot, and the whole soundstage shifts to one side, spaciousness collapses, and images become vague and unstable. This is the antisocial aspect: only one member of a group can hear good stereo at any one time. (The gracious host at a listenfest will take a secondary seat, allowing his guests to take turns sitting in the sweet spot.)

The Decca Mark V is the latest version of that English firm's unique "tip-sensing" stereo-matrix-ing pickups. The "matrixing" apellation refers to the fact that the Decca pickups do not use 45°–45° sensing coils, but use instead a combination of vertical and lateral-sensing coils. There is a single coil for lateral sensing, with its pole pieces brought down next to the tip. This is the tip-sensing feature, whose major attribute is that the stylus motions don't have to be conveyed along the length of an armature before reaching the transducing pole pieces. Thus there is virtually no possibility of the stylus vibrations being modified through flexing of the armature prior to their transduction into audio signals.

This low-output moving-coil cartridge can be fitted with different styli. The basic DL-103 has a 0.5-mil spherical tip, the DL-103S a Shibata tip. As of the spring of 1975, the '103S is being imported by American Audioport, Inc., in Columbia, MO. the '103 is being brought in directly from Japan by a few dealers. Our '103 was loaned by Music & Sound of California, the '103S came from Audioport.

They are not too similar in sound. The DL-103S is incredibly clean-tracking, with a light, airy high end, a subtle zizz on string tone, and a very slightly withdrawn quality similar to the sound of the Supex 900E, but not as overly rich-sounding as the Supex.

Do-It-Yourself (DIY) loudspeaker projects are quite common in the UK, where details about several excellent designs, including a recent one by Martin Colloms, have been published for public domain consumption. Stateside, the situation is rather grim, where only an occasional subwoofer project (always popular) makes it into the commercial magazines.
