In this space last January, I enthused about the sound of linear 20-bit digital recordings which, I felt, preserve the quality of a live microphone feed. "I have heard the future of audio—and it's digital!" I proclaimed, which led at least a couple of readers to assume I had gone deaf. Putting to one side the question of my hearing acuity, 20-bit technology has been rapidly adopted in the professional world as the standard for mastering. The remaining debate concerns how to best preserve what those 20 bits offer once they've been squeezed down to the 16 that CD can store. Sony's Super Bit Mapping algorithm and Harmonia Mundi Acustica's redithering device have been joined by new black boxes from Apogee Electronics, Lexicon, and Meridian; it appears likely that, in next to no time at all, all CD releases will be offering close to 20-bit resolution—at least in the upper midrange, where the ear is most sensitive.

This essay first appeared in the May 2005 Stereophile eNewsletter. But as the opinions and comments are still relevant in 2014 and in some ways the phenomenon of over-compression in recorded music (footnote 1) is just as bad, I thought it worth republishing.—John Atkinson

I write these words mere hours after returning home from Home Entertainment 2005, the Show cosponsored by Stereophile magazine that took place from April 28 through May 1 at the Manhattan Hilton. A full report will appear in the August 2005 issue of the magazine.

The Salon Son & Image has been organized for the past 4 years by Michel Plante and Sarah Tremblay, who were to be seen everywhere on the Show's opening day. I have been involved in running Shows for almost 30 years, and I must say that from the visitors' perspective and, I hope, the exhibitors', the 2010 event was superbly organized. Good signage, a great venue, and overall good sound, I take my hat off to Michel and Sarah. They even partnered with CEDIA for the first time at the 2010 Show to present "CEDIA University," a series of training seminars for custom installation. The evening of the first day, Michel thanked everyone in a short speech at the opening reception and wished them "Bon Salon!" before handing the stage over to the Give Band.

I couldn't resist posting one more photo of Bruce Thigpen's fan-driven infrasonic subwoofer, this time showing the drive-unit in operation. Loaded with an infinite baffle—it is in the next room—it fires into a foam-lined sub-chamber, which low-pass filters the residual fan noise, leaving just the awesome infrasonics to pressurize the room next door. Because the fan is providing the main motive power, just 30W of audio signal was required to create an spl of 115dB at 8Hz!

Sad news this week: We heard from Ken Kessler of the passing of legendary UK engineer Stanley Kelly, who died in his sleep on November 13, after suffering a stroke the previous week. Stan would have been 89 next month. While he was, of course, the "Kelly" of the classic Kelly Ribbon Tweeter, he was also one of the founders of Hi-Fi News and was the only person to have been listed on the English magazine's masthead since Vol.1 No.1, the June 1956 issue. In recent years, Stan had developed a series of high-sensitivity speakers for UK manufacturer Musical Fidelity.

Steinway-Lyngdorf's S-Series loudspeaker is tiny, at just 10.2" H by 7.8" W and 3.1" D. (My apologies for the grainy photo but the battery in my camera gave out and I had to resort to my iPhone 3GS for this shot.)

After Peter Lyngdorf left Tact, he went into partnership with the Steinway piano company to make a line of expensive speakers aimed not at audiophiles but at well-heeled music lovers. I was impressed by what I heard of the first of this line, which incorporates Lyngdorf's RoomPerfect acoustic correction, when I auditioned it in Manhattan a couple of years back, so I wasn't surprised when Steve Guttenberg button-holed me and told to go listen in the Steinway–Lyngdorf room at Axpona.

The S-Series subwoofer-satellite system ($22,100) was producing a big sound with the tiny satellites stood on a credenza against the wall behind them. Incorporating RoomPerfect correction, the speakers also use digital signal processing to produce a flat response, which Peter Lyngdorf explained allowed him to optimize the drive-units for maximum sensitivity. The two small subwoofers were placed in the room corners, with a crossover frequency (depending on the room correction necessary) around 200Hz

The accuracy of a hi-fi system's "soundstage" reproduction seems to be of paramount importance these days, just as a component must now have "transparency" to possess hi-fi righteousness. If the system in which that component is used doesn't give good soundstage, then the system's owner has definitely fallen by the wayside. But what defines a good soundstage? Stereo imaging must have something to do with it, I hear you all cry. (I would have said stereo imagery until Larry Archibald pointed out that imagery has far less to do with hi-fi than with good writing, something I'm sure we agree has no place in a hi-fi magazine.) OK, what defines good stereo imaging?

The people at Manhattan high-end audio retailer Stereo Exchange know how to throw a party. They proved it back in April with their Spring Fever event, and they look to surpass the success of that outstanding evening with their 25th Anniversary Celebration, this Thursday, November 5, from 3–9pm.
