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.
If you have read my reviews of the Ortofon M-15, the Shure V15-III, and the Decca Mark V, you have probably formed a pretty firm impression of which of the three contenders for the title "Best Pickup" is the winner. In case you haven't, though, here's a capsule wrap-up of our reactions to the three phono cartridges reviewed in May 1974.
A recent experience with two excellent loudspeaker systems and two of the top power amplifiers raised a question that has been cropping up more and more frequently these days: When one component sounds more toppish or more bassy than another, which one is really flat and which isn't?
The question arose this time in connection with some listening tests on a pair of FMI 80 speakers and a pair of IMF Monitor III speakers, using Audio Research Dual 75 and Crown DC-300A power amplifiers.

Not a new recording, and one that has already received raves in all the other audiophile publications, but if Stereophile is the only such magazine you read, you'd just better know about it, for this is the definitive symphonic recording to date.
Hey, kids, here's the Big News. We've been deluding ourselves all along, worrying about piddling little bits of distortion that we can't hear at all. How's your preamp distortion? 1% at 1 volt out? You have a perfect preamp—a veritable straight wire with gain! That ear-shattering shrillness is all in your mind, because it has now been demonstrated that the human ear cannot perceive distortion levels of less than 6–12% on "normally complex music." If you think you can hear 0.1%, you are deluding yourself.
Ye Editor had his first exposure to a true omnidirectional speaker system 15 years ago, while he was employed as chief equipment tester for High Fidelity magazine. The speaker was a most unusual-looking device for its time, being roughly a foot square and standing 3 feet high, with a "cube" of grille cloth at the top like a cupola. Inside the cupola was an 8" woofer facing upwards. Directly above it was the weirdest-looking tweeter you ever saw.
"As We See It" in the Stereophile issue dated Summer 1968 (actually published in 1970) noted the idealistic, glowing claims about how four-channel sound could put you right in the concert hail, but urged readers to wait before buying, to see whether quadrisound would indeed bring higher fidelity. We predicted it wouldn't—that whatever the potential of quadrisound (footnote 1), it would not be used to increase fidelity, but rather to play ring-around-the-rosy with music.
The top-of-the-line model from America's leading headphone manufacturer, these are bulky, heavy, very business-like in appearance, and very, very good.
The ESP-9 is dual-powered: from the AC line, or from the input signal itself, The power supply is rather large and heavy, and appropriate in appearance to the phones. Amplifier connections are via wires with spade lugs attached, and speaker connections are made to the rear of the power supply. A front-panel switch selects speaker or headphone operation, and terminates the amplifier outputs with 10 ohms in the Phones position.
Construction is typically top-of-the-line Koss: Rugged, nicely finished, and apparently very durable, and the phones are easy to handle. (Many headphones are so loosely pivoted on their headbands that they swing into impossible positions whenever you pick them up.)

Ever wonder just how much sound quality is lost by recording stuff on tape before making a disc? Here's your answer. This program of soft rock and cool jazz arrangements was recorded straight from studio to disc, and the sound is incredible! Suddenly, a veil that we never realized was there has been lifted, and we had the feeling we were listening to a direct-wire transmission rather than to a recording. We're not at all sure we will ever feel quite the same again about any. other recording, such is the dramatic difference in transparency and cleanness.
