Remember the scene in Oblivion where Jack cues up a record in his secret hideaway? I could expand here on the ratty condition of the record sleeves, but I'm referring instead to the clump of dust on the stylus—the "needle" for the analog-deprived. In the movie world, and in the absence of a proper stylus brush, he might use a finger swipe to clean it off (yikes!), but since he (and the movie's art director) has only recently experienced the vinyl enlightenment if at all, and in the absence of a proper stylus brush, he simply ignores it. The record plays nevertheless.

But this tome isn't about vinyl. It's about the sticky business of keeping our audio-video systems relatively tidy. Working on this should be at least an annual event for every A/V fan, and for the inveterate tweaker and/or reviewer it should happen even more often.

Begin with the equipment stand or rack...

Heat is the enemy of electronics, including all of that audio gear crammed into your A/V cabinet. In the early days of electronic entertainment, vacuum tubes (or as our Brit friends call them, valves) were the thing—the only thing. As one of my teachers once explained, the key to vacuum tubes was the little man with a switch inside. But he must have been sweaty, as a tube device could serve well as a space heater.

Back in the day our electronic entertainment consisted of little more than a radio. The family gave no thought to what was inside until one of the tubes failed, prompting a visit to the local drug store with its tube tester and ready supply of replacements.

Then came hi-fi and an interesting thing happened. Because of the heat issue, relegated largely to the output stages of an amplifier, separates were born. The separate preamp driving an amp on a separate chassis was a popular way to go.

The divide, between separates and the integrated amplifier (or perhaps AVR), still exists today in both the 2-channel and home theater worlds. Long forgotten is its genesis, since with solid state electronics heat is no longer an issue.

Or is it?...

Epson America recently filed a lawsuit against Vava (Sunvalleytek International Inc.), claiming erroneous ANSI Lumens claims for the latter's VA-LT002 4K UST (Ultra Short Throw) laser projector.

It's easy to get into the weeds on this subject (I pity the poor judge assigned to adjudicate the claim!). You'll usually see a projector's overall luminance specified in one of two ways: either simply in lumens or in ANSI Lumens. The latter spec must follow procedures established by the American National Standards Institute (ANSI). The former doesn't...

In case you haven't noticed, prices in the consumer world are creeping up. It's not yet a tsunami, but the signs are there. This should be a concern for everyone, and audio- and videophiles won't be immune from it. Some of the rising costs are due to unexpected events, such as the hacking of an oil pipeline, which might settle back in time. Others are due to government monetary policies, for better or worse in the unsettled time of Covid-19. Inflation is always produced when too much money chases too few goods. And there's no money tree in the back room of the Capitol in Washington. We're borrowing from Peter to pay Paul, but Peter can't object; he's just a printing press. The typical payback is inflation, a hidden tax on everyone.

Economics is a boring, black art, but it could inevitably affect our own little A/V corner of the wider world...

David Vaughn’s 2019 review of the SVS SB-3000 sealed subwoofer inspired me to request a pair of SB-3000s for a feature article on finding the best locations for dual subs. But because my listening space is open to much of house I had the urge to experiment with two larger, ported subs, so I pitted two SB-3000’s against a pair of PB-3000’s to see how they would hold-up against their big brothers.

THE VERDICT
The name Sonus faber conjures up visions of exotic speakers priced at a level that will buy you a reasonably nice house in some places. But a full 5.1 package from the company's new Lumina line will cost you less than a modest patio upgrade.

Loudspeaker manufacturer Sonus faber was founded in the early 1980s by the late Franco Serblin in Vicenza, Italy. It's been known since then for offering superb sound with classic Italian attention to style, with products aimed at buyers for whom price was at most a secondary consideration. But in recent years the company has tested more affordable waters, particularly in its home theater offerings, with the latest addition to its lineup, the Lumina Collection, designed to appeal to a wider range of listeners with real-world budgets.

Ken Pohlmann got the jump on me in his blog this week, but the recent permanent (?) closing of the Cinerama Dome theater in Hollywood is a significant event. Perhaps I can add a slightly different perspective.

When I lived in LA from 2000 to 2015 the Arclight theater in Hollywood was one of my go-to haunts whenever I wanted to see a top-drawer movie release in a premier theater. The Cinerama Dome was the main attraction in this multiplex, but the other Arclight screens were also impressive...

(Cue deep, sonorous narration.) In a world infested with giant, hungry bugs, what's left of mankind has hunkered down in underground colonies where they're safe (mostly) from being eaten alive. How this post-apocalyptic nightmare began is explained in the brief opening sequence of Love and Monsters, but in short it was mankind (as usual) that messed things up.

The big news story of last week wasn't out of Washington D.C., or about the current state of Covid, or who has just cancelled who or what, or even the new line of TVs ready to flood your local Costco, Sam's Club, Best Buy, or any number of other retailers. It involved a giant cargo ship, the Ever Given, getting stuck in the Suez canal with hundreds of other ships lined up behind it and unable to get through with their cargo. What's this have to do with home audio and video?

Building your own speakers from scratch Is an activity I've written about before. But that first blog is now accessible only by delving deeply into our Wayback Time Machine, so a revisit to this intriguing audio subculture is worth a follow-up here. Read on to find out if you have what it takes to take on a DIY speaker project.
