The Monitor Audio R300/MD ($669/pair) debuted at the 1988 SCES in Chicago. English company Monitor Audio is one of the pioneers in spreading the use of metal-dome tweeters in relatively low-cost loudspeaker systems. The tweeters they have designed in conjunction with SEAS and British manufacturer Elac may have now found their ways into a number of designs from competing manufacturers, but there is no doubt that Monitor leads the way. The new R300/MD features a new ¾" version of the SEAS 1" aluminum-dome unit Monitor introduced with their R652/MD (reviewed in Vol.10 No.5), in conjunction with an 8" doped paper-cone woofer.

First stop on the show's final day, a return to the High End Zone/Perfect8 Technologies room on the 2nd floor. I couldn't cover this exhibit on opening day because the visually striking Perfect8 Technologies Point Mk.III loudspeakers ($125,000/pair), a point-source dipole design with Symmetrical Radiation house in propriety "super silent glass," got trashed—badly trashed—in transit, and their replacements did not arrive in time.

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DL-103S is incredibly clean-tracking, with a light, airy high end, a subtle zizz on string tone, and a very slightly withdrawn quality similar to the sound of the Supex 900E, but not as overly rich-sounding as the Supex.
