First a confession: a lot of audiophile speakers can't rock out. They're "voiced" to sound best with acoustic jazz or classical music. Nothing wrong with that, but when you want to party some of them can't cut loose. The new GoldenEar Technology Aon 3 is very much an audiophile-oriented design, so sure, it sounded clear and clean playing Miles Davis' "Kind of Blue."

But what really made me sit up and take notice was the way the Aon 3 knocked out the Drive-By Truckers "Go-Go Boots" album. This CD sounds like … Read more

Sound-quality advances in headphone design show no sign of slowing down, and even old names like Philips and Sony are getting serious about making great-sounding headphones. Sadly, those brands aren't attempting to make anything that could be compared with the world's best, like the JH-3A headphone/amplifier system, from JH Audio.

That company's founder and designer, Jerry Harvey, started building in-ear monitors for rock bands in 1995. He counts Lady Gaga, Alicia Keys, Aerosmith, Foreigner, and Linkin Park as customers. Harvey is currently with the Van Halen tour--the band uses his 'phones onstage--and Harvey uses their feedback to improve his designs.

The JH-3A is an amplifier/in-ear headphone system, with analog and digital inputs with up to 24-bit resolution and 96kHz sampling rates. I've used portable headphone amplifiers before, and they can sound great with all types of headphones, but the JH-3A takes in-ear headphone performance to another level.… Read more

We've seen plenty of apps promise to allow musicians to play with each other in real time across the Internet, as if they were in the same room. However, they generally didn't work perfectly due to the signal taking too long to traverse an Internet already teeming with cat videos and Angelina Jolie's right leg. As for adding video too--it's just not happening.

The answer could be LOLA--not from the eponymous Kinks song, but standing for "LOw LAtency."

Unlike apps that use the Internet, which either tend to include a delay or employ … Read more

Merely buying a great subwoofer is no guarantee you'll wind up with great bass. There are too many ways to squander its performance potential. That's why putting in the extra effort to achieve proper subwoofer setup is crucial.

The No. 1 setup myth is: You can place a sub "anywhere" in the room. Well, of course you can, but chances are it won't sound very good.

The "anywhere" strategy might be an even more tempting option with wireless subs, which sometimes come with claims that they can be placed 60 feet from the … Read more

Let's start with the most common fallacy about audio: good sound is good sound. Movies and music have very different requirements, so I recommend first acknowledging your preference for movies or music, and steer the system's performance strengths one way or the other with the right mix of speakers and electronics.

How different is movie sound from music? Let me count the ways: Today's films boast nearly unlimited soft-to-loud dynamic range; dialog is mixed to the center channel; surround effects may be ambient or point-sourced; and deep-bass demands can be extreme. Just about every feature film released … Read more

For me a great hi-fi doesn't necessarily have to be the best-sounding one.

It's more about a sound that draws me in. One CD or LP leads to the next, and I don't want to stop to eat, read, go to bed, or watch TV. A great hi-fi is one that lets the music cut loose. Even cheap gear might have what it takes to get my juices flowing. Take the Velodyne vPulse in-ear headphones; they make too much bass and are far from the most refined headphones in my collection, but I keep using them. I … Read more

I admit it: I like big speakers, the bigger the better as far as I'm concerned.

Big speakers sound more realistic, they play louder with lower distortion, and they have better and deeper bass than small speakers. Then again, I'm an audiophile, so I prioritize sound quality over almost everything else. I also know big speakers are out of the question for most folks, but what if there were a reasonably sized speaker that produced big-speaker sound? The Atlantic Technology AT-2 is such a speaker.

It was just last year when Atlantic's AT-1 tower speaker ($3,000 a pair) rocked the audiophile world and garnered a slew of rave reviews, so when I heard the smaller AT-2 ($1,800 a pair) was about to be released I just had to get it for review. It did not disappoint. … Read more

I've listened to a lot of speakers over the past thirty-odd years, and I can tell you this, they're all imperfect.

No hi-fi or home theater sounds like live music, and not a single one of the most exalted high-end speakers has truly flat frequency response.

Of course, everyday speakers are less accurate, which is why just about every receiver sold today has a calibration system that corrects speaker anomalies and tames room acoustic problems.

That's all fine in theory, but most speaker calibration systems only change rather than improve the sound of a hi-fi or home theater. So I'm a bit of a skeptic about the benefits of this type of processing, but I finally heard a correction system that delivered the goods. It's the DEQX HDP-Express. I listened to it over a very high-end system (owned by DEQX's publicist).

The sonic transformation was at once subtle and dramatic. I first listened to the system without any correction, and the sound was excellent. The speakers were large floor-standing towers (Focal Utopias). I played a few recordings I know well, and the sound was beautifully balanced and natural.

Ah, but then my host switched on the DEQX speaker correction, and the sound of the "Wynton Marsalis & Eric Clapton Play the Blues" CD snapped into focus.… Read more

I'm hoping the whole celebrity-branded headphone shtick will soon run its course, but I have to admit Monster's new Earth Wind & Fire Gratitude in-ear headphones are pretty spectacular.

Earth, Wind & Fire was one of the most popular funk bands of the 1970s, so naturally they were primed to attach their name to a headphone. That's fine, but I have to judge a headphone on its build and sound quality, and the Gratitude is a very decent headphone indeed. The heavy gold accents on the earpieces were a little gaudy for my taste, but that's … Read more
