With most speakers or headphones, you're stuck with the designer's sound, but with the Logitech UE Personal Reference Monitors (PRM) you get to play headphone designer and dial in exactly the sound you want.

Each pair is totally unique; they're built with the individually designed equalization curves you selected. My PRMs sound absolutely amazing, but I'm a little biased, I designed them to please my ears! Every PRM buyer will do the same, and if they totally screw up and hate the result, Ultimate Ears will give them another try. Each PRM set is handmade in UE's facilities in California.

The price for this level of customization doesn't come cheap, though; the Personal Reference Monitors sell for $1,999. That's extreme, but so are $285,000 luxury cars. I cover the full gamut of audio, from affordable to the craziest expensive gear. … Read more

There are a number of terrific small subwoofers on the market, but all of the best subs are big. The little ones can certainly make bass, but the quality and quantity of the larger subs' deep bass is considerably better. You can literally feel the difference -- deep bass is as much felt as it is heard.

I remember the impact a big sub made when I reviewed the Outlaw LFM-1 (now upgraded to the LFM-1 Plus, $549). The LFM-1 weighs 58 pounds and measures 21.75 inches tall, 15 inches wide, and a whopping 22 inches deep. It had … Read more

I met Julie Glick a few months ago with some folks from Ultimate Ears at a Head-Fi meeting in NY. UE was promoting a new set of custom-molded in-ear headphones, the Personal Reference Monitors, which are just now entering full production. In her NYC office, Glick can fully demonstrate these unique headphones, which are not only custom-molded to your ears but fine-tuned, soundwise, to your liking. Ultimate Ears technicians use the frequency curve you create to build your Personal Reference Monitors. I crafted my EQ curve in Glick's office; it was a lot of fun to design my sound. … Read more

Andrew Jones has a degree in physics, but his real passion is speaker design. He worked as a research engineer for KEF, Infinity and now with Pioneer, and he's chiefly responsible for their ultra high-end TAD Reference line of speakers that sell for upwards of $80,000! So a few years ago when I first heard that Jones was working on a line of superaffordable speakers for Pioneer, I didn't believe it. I said, "You mean that Andrew Jones? No way." Well, it was that Mr. Jones, and the speakers were astonishingly good. The now-discontinued 5.1-channel, … Read more

Oh good, I can get one second more sleep the night of June 30. In an effort to keep our extremely accurate atomic clocks in line with the more arbitrary nature of the way the world wobbles, we're getting a leap second this weekend.

Sure, it's not as dramatic as what happens during a leap year, but it's still exciting for clock aficionados, science geeks, and time lords. The leap second will be added to Coordinated Universal Time at the end of the day on June 30.… Read more

Gone are the days of walking over to the bookshelf, grabbing an Encyclopaedia Britannica, and flipping through the pages to look up whatever piqued one's curiosity. The leather-bound print edition set of reference books is now defunct, the company announced today.

However, Encyclopaedia Britannica is also quick to say that this change isn't its swan song. Now, in the digital age, the company will focus on its online encyclopedias and educational curriculum for schools.

"In spite of our long history with print, I would like to point out that no single medium, neither books nor bits, is … Read more

In the latest build of iOS 5.1, now beta 2, Apple has finally decided to take steps against the popular rumor site tactic of rifling through iOS code to find references to new hardware models.

These references, typically something like iPhone3,1, were a great way for rumor sites to predict forthcoming hardware devices, accurately assuming that their inclusion in the iOS code meant they were being tested.

With Apple's release of iOS 5.1 beta 2, things have changed. Apple has now included device references for dozens of new devices including AppleTV10,3 and iPhone11,3. By … Read more

The Axpona (Audio Expo North America) high-end audio show came to New York on Friday and Saturday. It was a fairly small affair, but I managed to find more than a few astounding sound demos. The most amazing of all came from a tiny S-Series subwoofer-satellite system from Steinway Lyngdorf, which produced an audiophile-grade, lifestyle-oriented system. "Lifestyle" audio is usually synonymous with mediocre sound, but this very small system produced extremely good sound. The S-Series speakers may be just 10.2 inches high, 7.8 inches wide, and 3.1 inches deep, but they (and their matching subwoofers) … Read more
