Matt's turntable, amp, and speakers.
(Credit: Matt Calderone)What's the definition of a great hi-fi? It's the one you're listening to. Not just for background "listening," but actual, focused listening.
Investing a lot of money on a hi-fi isn't the only way to get there. In fact, spending as little as possible on decent gear is the best way to get acquainted with good sound. Who knows, you might become an audiophile.
My friend Matt Calderone might be on his way. He was given a used Denon DP-7F turntable, and recently bought a Kenwood KA-701 integrated stereo amplifier on eBay and a pair of Klipsch speakers through Craigslist. All told, he spent less than $200.
Calderone is 26 years old so I was curious about how and why he wound up with a hi-fi. He says he's always been interested in LPs, and he likes listening to them over a decent stereo, not computer speakers. Calderone thinks good speakers make a big difference.
It's not just that the sound is better, music engages on a different level when heard over a hi-fi. Calderone frequently winds up just sitting on the couch and get this, he listens to entire records! The music is the main focus; vinyl has that effect on some people. Calderone is going to add a CD player soon, but for now his system is analog only.
The hardest part of buying a used hi-fi is picking the right gear. If you're new to hi-fi ask an older relative who knows audio about which brands are worthy, but for starters I'd recommend steering clear of Sony and Bose products. I like Creek, Denon, NAD, Onkyo, Pioneer, and Yamaha amplifiers and receivers; look for used Advent, AR, Boston Acoustics, DCM, Epos, Infinity, Klipsch, Magnepan, Mirage, Monitor Audio, NHT, Polk, Snell, or Vandersteen speakers. For a few hundred bucks you can put together a very listenable used system.

The little black squares on the top of the billboard are the speakers.
(Credit: Steve Guttenberg)UPDATE: An earlier version of this blog incorrectly described the technology used in an advertisement for the A&E's TV show Paranormal State. The technology, developed by the Holosonic Research Lab, uses a beam of ultrasound as a "virtual source", which changes into audible sound as it travels through the air. Please read the technology's inventor, F_J_Pompei's comment or visit the Holosonic Research Labs site to learn more.
The folks who heard the ad for A&E's TV show Paranormal State emitted from a billboard in New York City's Greenwich Village must have thought it was pretty weird. As they walked into the targeted area they were exposed to highly focused sound. One big advantage of the technology is that it doesn't contribute to ambient-noise pollution. I went to the Village a few days ago to check out the technology, but A&E had already pulled the plug. A&E's PR agency told me the speakers were only active during the first week of the campaign, so you gotta wonder, if it was such a great idea, why turn it off? The billboard is still there.
The phenomenon was covered in a terrific segment on the December 14 On the Media radio program on my local NPR station, WNYC.
The "Audio Spotlight" technology used in the billboard was developed by Holosonic Research Lab. Their Web site claims that "through a combination of careful mathematical analysis and engineering insight, the Audio Spotlight sound system has become the very first, and still the only, sound beam system which generates low-distortion, high-quality sound in a reliable, professional package." Well, I'm not so sure about that.
American Technology Corporation's HyperSonic technology also focuses sound into small beams. The Brooklyn Historical Society is currently using Hypersonic speakers in an exhibit, "In Our Own Words: Portraits of Brooklyn's Vietnam Veterans." The show features life-size photographs of the veterans, and when you stand in front of the portrait, the sound system automatically turns on and you hear the soldiers' pre-recorded stories. Many visitors can simultaneously experience the exhibit without hearing other sounds (because the sound is so tightly localized each patron hears only the intended sound).
I found the Hypersonic system worked quite well, but its fidelity was rather limited (it sounded like a small table radio). The oral histories are really interesting, and the Brooklyn Historical Society has a number of exhibitions on view. Check it out.
