In September 2019, I made an afternoon visit to National Sawdust, a vibrant, innovative performance space in Williamsburg, Brooklyn, to attend a demonstration of the new Constellation and Spacemap systems installed there by Meyer Sound. According to Meyer Sound designer Steve Ellison, the two systems permit control of the space's acoustics (Constellation) and empower performers and sound designers to construct a soundscape (Spacemap) in which voices, instruments, and other sounds can be located virtually anywhere within as well as beyond the confines of the performance space.

The buzz at the 2019 Audio Engineering Society (AES) convention in New York was immersive audio, as it has been for the last several years. I witnessed developments that may have a big impact on the future of multichannel audio.

Upon hearing about this new product from Benchmark Media, the LA4, my mind turned to Laurindo Almeida, Bud Shank, Ray Brown, and Shelly Manne—the original L.A. Four jazz quartet. No such association was intended, however: the "4" merely designates change from previous Benchmark designs.

The GoldenEar Triton One.R is the successor to the original Triton One, improving on that model in both appearance and function, with features that first appeared in the Triton Reference.

Externally, the Triton One.R is a 54" tall by 8" wide by 16.65" deep tower that appears even slimmer than those dimensions suggest. In lieu of the sock-like fabric covering used on GoldenEar's less expensive speakers, the One.R, like the Reference, is finished in a high-gloss black, with large rectangular grille-cloth panels on the lower portions of each side and a curved, full-height front grille whose edges blend smoothly into the side panels.

This is the 100th and—surprise!—final edition of Music in the Round. MitR began in mid-2003, shortly after SACD and DVD-A discs made high-quality multichannel music convenient and widely available. At the time, I was convinced that multichannel reproduction was superior to stereo because it was able to reproduce the full sound of the performance—not just the performers. Stereophile's founder, J. Gordon Holt, had promoted this idea many times, but the appearance of the new media finally brought it to a wider audience.

There is necessity as well as comfort in having a long-term reference recordings and, system. The necessity derives from the familiarity with the reference that allows for comparisons and contrasts with the equipment being tested. The comfort that comes from the familiarity lets me relax and enjoy recreational music, relieved from the need to focus my attention intently on the sound. I do relish getting my hands on lots of interesting audio equipment and getting to play it in my own home, but it's like a two-month one-night stand: The new stuff usually goes back even if I am impressed. I don't change my audio equipment often.

At first glance, this active, DSP-controlled loudspeaker system, with dynamic drivers firing to front and rear, may seem an alien invader from the world of recording and mastering monitors made by such brands as Neumann and Genelec. I wouldn't dispute that perception, but I offer another perspective: The engineering that has gone into the Dutch & Dutch 8c ($12,500/pair) is an all-out attempt to meet the goals that all designers of high-end speakers hope to attain: wide, smooth frequency response; sufficient and linear dynamic performance; crossover management; a cabinet free of audible resonances and edge diffraction; control of the dispersion of sound energy throughout the audioband.

As I wrote before in these pages, I have long been acquainted with French electronics manufacturer Trinnov. Years ago, at an Audio Engineering Society convention in New York, a Trinnov rep used a mastering console equipped with their processor to move, at will, the sounds of instruments around the 3D soundstage and left me thoroughly impressed. That was before my conversion from stereo to multichannel music listening, and before the blurring of borders between home theater and mainstream audio.

Sometime near the turn of this century, I wandered into a demo room at a Consumer Electronics Show and discovered, in the exhibit of a company I'd never heard of, an integrated amplifier that sounded clean and refreshing. It was the only product Hegel Music Systems displayed at that CES, and I don't recall its name or the associated equipment, but I've always remembered that model's striking appearance and impressive sound quality.

One of the recurring themes of this column has been my search for servers that will support the playback of high-resolution multichannel files with DSP for speaker/room equalization (EQ), as well as the format conversion and downsampling that are often part of those processes. Because most EQ software is PCM-based, format comversion is needed to convert DSD files to PCM. In addition, because most EQ products work within a limited range of sampling rates, PCM files sampled at high rates may have to be downsampled before being subjected to EQ. Those of us who use home-theater preamplifier-processors and audio/video receivers (AVRs) should be familiar with such constraints.
