It's August as I write this, and I'm looking back at some things that need to be discussed, and forward to the fall audio shows—particularly the 2014 New York Audio Show, which, by the time you read this, will have been held in Brooklyn, September 26–28. I grew up in Brooklyn, not in "the city," Manhattan, a place that we traveled to only for special reasons. Audio shops were rare in Brooklyn—I remember only Audio Exchange—but in Manhattan there was a small cluster near Grand Central Station, there was Lafayette Radio near the Holland Tunnel, a few scattered elsewhere, and the magnet of Liberty Street in lower Manhattan, where more than two city blocks were packed with audio shops.

My experience at last May's Home Entertainment 2004 East confirmed that even a big cheerleader for discrete, high-resolution multichannel music must be realistic about the vast heritage of two-channel recordings, which will dominate collections for years to come. Although we can enjoy these recordings with a good stereo system, a multichannel system can offer options that give them new life without superimposing false and disturbing directional effects or smearing the two channels around and behind the listener.

While Dolby Atmos, which adds height information to both cinema soundtracks and domestic surround-sound reproduction has created a strong buzz in the mainstream market for home-theater A/V receivers and preamplifier-processors, it's too early to know what, if any, impact it will have on music-only recordings. I'm not sanguine about the prospects—as impressive as I've found Atmos to be for movies, the expansion of sources to the vertical plane would seem to be of little value for music performed on acoustic instruments. Moreover, it seems unlikely that mainstream record labels will adopt this format any more than they have embraced multichannel or even high-resolution audio. Sound of CD quality or below still dominates the recording industry, even if hi-rez downloads are a bright but tiny point of light.

It seems that the rising popularity of downloading of music files is going to affect not only the distribution of high-resolution recordings but also the availability of multichannel recordings. Once freed from the technical, marketing, and distribution constraints of physical media, large hi-rez and/or multichannel files can more easily be made available. The established providers of music downloads, such as Acoustic Sounds, HDtracks, and iTrax in the US, are being joined by: sites that specialize in particular genres of music, such as the Classical Shop (UK); other sites, that focus on particular formats, such as Native DSD Music (Netherlands) and the Promates Music Store (DXD files, Denmark); and music producers, such as Blue Coast Music and the Boston Symphony Orchestra (BSO.org), that offer their work directly to listeners.

It has been a disrupted spring. Late last year, my wife and I committed ourselves to a long-needed renovation of our main living space: an apartment in Manhattan. Articles, books, and TV shows have illuminated the trials and triumphs of home renovation, but as far as I know, none has included a redo of the listening room of an obsessive audiophile, let alone one who is also an audio writer facing copy deadlines.

Outside of the listening I do for this column, I always audition, assess, and review components without using any equalization or room correction—primarily because I assume that most Stereophile readers listen in two-channel stereo, and that most aren't all that interested in EQ. Besides, two-channel is the tradition I come from, and my first instinct is to try to get at the essence of the individual component itself, without applying extraneous tools or accessories. John Atkinson's bench tests are based on the same philosophy.

In my last column, in the November 2015 issue, I talked about Marantz's AV8802A preamplifier-processor and two accessories: UpTone Audio's USB Regen, and a DIY battery supply for my DAC. This month's column is all about accessories, and for me that's unusual. Some items, like interconnects and speaker cables, are usually considered accessories because they're not fundamental components (eg, source, amplifier, speaker), even though they're essential to getting any sound at all.

With the atomization of the playback of digital files into storage, servers, streamers, format converters, and DACs, I find that I've accumulated many miniature power supplies: small pods and wall warts. Most of these are generic switching devices made by companies other than the manufacturers of the components they power, and even those not designed for audio systems are, of necessity, at least adequate for the task. Because many of these supplies are indistinguishable from each other, I've taken to labeling them with sticky notes to remind me which goes with which component. Nonetheless, I'm concerned that they're no more than the commodity power modules available for a few bucks each on eBay. Whenever I think of the four or five of them clustered behind my equipment rack, I begin to suspect them of plotting revolt against the fancy gear they serve.

The number of devices that can constitute a home-audio streaming system ranges from one—a laptop computer running a music program to play internally stored files—to x the unknown. These days we have storage devices, servers, streamers, renderers, bridges, controllers, players, and DACs, at least one of which is hoped to have a volume control. Any combination of these elements can be put in a single box and described by one of many new hyphenated product categories—or can be given a name along the lines of exaSound's PlayPoint Network Audio Player: a model designation that at least hints at this product's ability to play music. Let's see what else it can do . . .

The SOtM sMS-1000SQ Windows Edition with AudiophileOptimizer and Roon: Not only does that very long name require finger-twisting shifts between upper and lower case, it really doesn't tell you what the sMS-1000SQ WE is.

Korean manufacturer SOtM, Inc. describes it on their website as a "music server based on Windows Server OS besides the original Linux [Vortexbox] OS based sMS-1000SQ." I'd describe it as a Windows-based PC that's designed and optimized to manage a database of music files and stream the music to local or networked DACs, and that supports multiple options for file management, playback, and target devices. (Hmmm: that's not much better, is it?)
