You don't see the phrase "world-class" associated with American-made consumer goods. TVs, iPods, computers, and cameras are mostly designed and built in other countries. The U.S. may be the world's leading consumer state; we just don't make the very best products here anymore.

High-end audio may be one of the few remaining industries where America still designs and builds the very best products. I'm proposing an all-American hi-fi system that could be installed in the White House. It would be the sort of hi-fi the president could, after a hard day's work … Read more

High-end audio, just like high-end everything else--cars, clothes, watches, boats--is in large part about style. Sure, high-performance is part of the appeal, but exquisite build quality and eye-catching designs are essential for market success.

With that in mind I put together a nice assortment of some of the more dazzling high-end components currently on the scene.

Magico's speakers are built with solid, massively inert structures designed to ensure the only sound you hear comes from the speaker's tweeter, midrange, and woofer drivers. No other speaker I've heard approaches Magico's resolution and precision. The company's latest designs upped the ante and now feature even more extensive frames designed to quell structure borne resonance to produce the highest-resolution sound possible.

Founded in 1991 by legendary audio designer Nelson Pass, Pass Laboratories, sells its unique amplifiers, preamplifiers and speakers throughout the world. The company has been based in Foresthill, California, since its beginning, and is widely regarded as one of the most innovative audio brands in the world. Many Pass Labs amplifiers, like my XA100.5 are pure Class A designs, and deliver breathtakingly beautiful sound.

The Ayre MX-R mono amplifier (you need two for stereo) is a looker, but pardon me for a second while I get tweaky and gush over the MX-R's zero-feedback and fully-balanced circuitry. Ayre's founder and chief engineer Charles Hansen invests vast amounts of time fussing over the tiniest circuit details, listening obsessively to eke out a sound that gets his designs ever closer to perfection. Some of the MX-R's resistors and capacitors are built to his specifications.

The Krell Modulari Duo Reference is a blatantly original, thoroughly masculine design, but at 44 inches tall, 11 inches wide, and 29 inches deep, it can still fit in average size rooms. Each speaker weighs 345 pounds, it's fair to assume the bulk of the weight can be attributed to its thick-walled aluminum construction. If the goal was to make an absolutely dead cabinet, I'd say Krell has done it. The speaker's design shows a clear aesthetic kinship with Krell electronics.… Read more

It's the hi-fi's job to produce the sound of music encoded in a recording.

Does how well or how accurately it produces the sound affect musical enjoyment? I'm not so sure about measurements; they just define distortion levels, power rating, and frequency response, but they don't have all that much to do with good sound. Good sound is much harder to nail down; we like what we like. You know good sound when you hear it.

Studio recordings rarely sound "live," or even realistic. How could they? Chances are the band never played the entire tune together "live" in the studio. Their music was patched together from bits and pieces, overdubbed, pitch corrected, rhythm corrected, EQ-ed, dynamically compressed, and processed in a gazillion ways. Of course, a lot of that also goes into modern "concert" recordings. So what constitutes a good sounding recording is pretty impossible to define. Play it back over a great system and what do you hear? Does it get your blood pumping?

So the question really is, does the music fully engage the listener? Sometimes, the better the hi-fi, the more music the listener hears, the more they like the music. Why that is? I don't know. … Read more

I'm a middle-aged guy, so sure, I read the CNET review of the new Dodge Challenger SRT8 just to get vicarious kicks imagining what it's like to drive a 425-horsepower muscle car. It sounds like a real thrill ride, and sure it's a serious gas guzzler: "The EPA rates the Challenger SRT8 at 14 city mpg and 22 highway mpg. However during our leadfooted testing, we only managed 13.7 mpg over a mixed city and highway cycle."

Even so, I suppose the Challenger's tested price of $43,730 will place it in the affordable range for a lot of folks, or let's be honest, guys. It's a car to get noticed in, but no one's fooling themselves into believing the SRT8 is merely reliable transportation. It's a toy, and if you can swallow the fuel bill, it's a heck of a ride.

Same can be said about high-end audio. It's not practical and it can be expensive to run, but once you get used to what it can do when it's playing your favorite tunes, a $500 HTIB won't cut it anymore. High-end audio isn't an appliance, it's supposed to get your heart pounding and blood flowing, not so different than the SRT8.

Thrill seekers lusting after a muscular audio system equivalent of the SRT8 should check out the following system.

Muscle cars are as American as apple pie, so I went for American made hi-fi where I could. I reviewed Klipsch's mighty RF-83 tower speaker ($2798/pair) for Home Theater magazine last October, but it's still a current model. With three 8-inch woofers and a 1.25-inch horn-loaded titanium diaphragm compression tweeter, the RF-83 mos' definitely will rock your world. Add the 12-inch Klipsch RT-12d subwoofer ($2,199) to ensure the deepest and tightest low bass. … Read more

Back in the day, we built great cars and the best TVs. And our advanced engineering was the envy of the world.

That was a long time ago. Today "world-class" design and manufacturing is mostly sent off-shore to Europe and Asia. American companies market and distribute products made somewhere else. According to American Economic Alert, the U.S. has imported $250 billion worth of goods and services more than we exported so far this year.

High-end audio is one area where made in America products are still truly world class. While the major brands like Audio Research, Ayre, … Read more

Information is the new currency. When it comes to social-networking sites and many other online enterprises, your attention is the product that is being sold. So it is not surprising that data mining, particularly efforts to link your online behavior to specific opportunities to market to you, is an exploding trend.

Data mining in itself is not inherently good or bad, but it raises many social issues whose implications we all need to understand and include in our ongoing dialogue. Data mining has benefits, including an opportunity to create a customized online experience that truly serves you better. Misuses can lead to serious breaches of privacy. I encountered several stories on data mining Tuesday that caught my attention.… Read more
