In the beginning, Edison created the phonograph, and it was good. It was also monaural. The vertical modulation (referred to as hill-and-dale recording) of the groove neatly encoded the amplitude variations of the analog-input waveform and likewise could reproduce the waveform. If engineers had stuck with hill-and-dale, the world would be a very different place. But they kept tinkering, as engineers are wont to do, and they found an improvement.

Referring to the sound of the 12-cylinder engines in Ferrari cars, conductor Herbert von Karajan said it was, "a melody that no conductor would ever be able to reproduce." Considering that the maestro was not modest when speaking of his abilities, that is quite a compliment. He was right, of course; some engines, tuned with the right exhaust, yield a glorious sound. With further tuning, apparently they can also yield glorious music.

Quick. What's the company everyone loves to hate? The cable company, of course. The aggravating installation, the inexplicable outtages, the maddening programming bundles, and the fees. Oh yes, the fees. But there's hope, and possibly change. President Obama has endorsed a proposal that would eliminate perhaps the most annoying cable TV fee. That's good, right?

I am sorry. Only certain people will be allowed to read this column. To ensure that you are qualified, you must first correctly answer this question: What is the relationship between cassettes and pencils? If you can answer that, feel free to read on. If you can’t, please move on.

Vizio recently unveiled its new P-series models. And they are pretty impressive, featuring 4K UHD and the very cool SmartCast app that essentially builds in all the capabilities of Google Cast. Since they are Vizios, they are very competitively priced. Very nice. The problem is, if you want to be a stickler for details, these devices aren't actually TVs.

Every audio and video gearhead is familiar with the world-famous Lirpa Labs. We can count, using many of the fingers on our hands, the number of wonderful Lirpa products we have owned over the years. Whether you have an average IQ allowing you to recite the alphabet from A to Z, or a super IQ and can recite it from Z to A, only a few people can truly comprehend the genius of Lirpa. Yes, indeed. Lirpa. Yes, indeed.

Depending on how long you keep your cars, it's entirely possible that your next car will drive itself. Even if you're two years into a three-year lease, given the furious development of autonomous technology, self-driving cars are a fait accompli. But more to the point, given the interests of this site's readers, self-driving cars open the door to entirely new kinds of vehicle entertainment systems. Case in point: this patent recently issued to Ford.

Sonos is a terrific company with terrific products. I reviewed their first-generation wireless speaker, back when no one had ever heard of streaming, and it blew my mind. Since then, of course, Sonos has become the Gold Standard for whole-house playback. But suddenly, seemingly out of nowhere, Sonos is changing course and laying off employees. What the heck?

I'm on record (ha!) stating my opinion that the vinyl resurgence is socially and morally significant. Interest in vinyl is up, vinyl sales are up. Are downloads and streaming in trouble? Well, of course not. Still....

Which of the following statements is false? 1. The sun rises in the east. 2. The hands of a clock go clockwise. 3. New technology is always better than old technology. This last statement, of course, isn’t quite as gospel as the others. Sometimes old technology has advantages that cause it to linger longer than we’d expect, or in rare cases, even make a comeback.

When's the last time that Circuit City crossed your mind? It's probably been so long that you can't even remember the last time you thought about it. And yet, the name Circuit City is instantly familiar to you. That's called name recognition. And clearly, rather than starting from scratch to build name recognition, you'd prefer to start with something well known. That is why Circuit City is being resurrected.

You've done the factory tour at Zuffenhausen. Eight times. You once got in a fight and lost a canine, defending the IMS bearing in your M96 engine You patiently explain to newbies why the ignition switch is on the left side. Of course, you have "911" tattooed on your bicep. And, you just bought a Porsche Design soundbar.

What do Hunter S. Thomson, Philip K. Dick, and L. Ron Hubbard all have in common? For starters, they all use an initial in their names, and anyone who does that is obviously trying hard to appear to be intellectual. More important, I think they would all have enjoyed attending this year's CES.

You probably haven’t heard of Maroo Audio. The company, after all, is just launching this year. But based on the sound quality of its initial products, you might want to hear more from Maroo Audio.

ARCHT Audio (pronounced “ark” as in “architecture”) arrived on the audio scene last year with its ARCHT One wireless speaker, following its Kickstarter campaign in 2014 that raised $242,000 from over 500 backers. Following on that success, ARCHT is debuting the Mini speaker.
