For a couple of years, I have been following Prague-based Okto Research. At first, Pavel Krasensky, the founder and hardware developer, offered audio design ideas and DIY modules that I found tantalizing. For example, there was a dandy-looking ESS 9038Pro Sabre–based output module and some appealing power supply modules—but to use those, the buyer had to manage inputs and integration on their own.

Then, finally, last year, Krasensky released the dac8 PRO, an 8-channel D/A processor with USB input and output, 8 channels of AES/EBU input, and 8 channels of balanced (XLR) analog output as well as a headphone output.

My, how we've grown! The experience that convinced me of the inevitability of streaming was in 2010 with the tiny, tidy Logitech Squeezebox Touch that, despite being discontinued and disowned by its manufacturer, still has a cult-like following. Since then, we have seen an explosion of devices for file playback from local or nonlocal storage and web streams.

On the cold and sunny morning of February 19, 2020, a dozen or so audio critics and writers gathered at Gilmore's Sound Advice on New York's far West Side to see some new NAD and DALI products that had been unveiled the prior month at CES. It was a friendly group, and we kibitzed over coffee before clustering in the arranged seats for presentations and auditions. I doubt any of us realized that it would be the last time for the foreseeable future that we would experience this familiar rite.

Some contentious issues will not be resolved in my lifetime: vinyl vs digital, tubes vs solid state, subjective vs objective, streaming vs physical media.

Also, subwoofers vs no subwoofers in a stereo music system.

This unique device is a solution to a problem that previously couldn't be solved.

There are, of course, any number of little boxes that can extract audio from the HDMI video bitstream; they began to appear on the market to fill a need for a way to route audio from a player's HDMI output In the recent past, you could buy a good-quality—even audiophile-grade—universal player and listen to SACDs via its good-sounding analog outputs. But good-sounding universal players are becoming scarce.

Back in the Dark Ages, loudspeaker design was commonly based on semi-enlightened experimentation, with new enclosure configurations appearing almost monthly in professional and consumer journals. One of those, published in Wireless World in October of 1965, was A.R. Bailey's transmission line, a long, selectively resistive, folded-and-sometimes-tapered tube that loaded the back of the (woofer) driver for low-bass reinforcement.

The components I needed to choose for my first system were never in doubt: a turntable or record changer, an integrated amplifier, and a speaker. One of each, please, in those mono days.

Today, even in stereo, that trinity would be regarded as rather traditional—or, if you prefer, purist. Digital has exploded the range of source options and loudspeaker options. Yet amplifiers have not changed much in how and what they do.

For a decade, the sound of the Vivid Giya loudspeakers, which I had heard only at CES in private demonstration suites, beguiled me. My positive impressions were completely consistent from one show to the next—but then, so were the host and the surroundings. I had to wonder how much those factors contributed to my impressions.

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.
