Sony MDR-R10: The world's best headphone?

I've heard most of the world's best headphones, but somehow missed the Sony MDR-R10. Only 2,000 were made. Production started in 1989, and at $2,500 a pair, it was the most expensive headphone in the world. The headphone cognoscenti scooped them all up years ago, and right now MDR-R10s rarely come up for sale. When they do, they usually go for more than $6,000!

The MDR-R10's 50mm "Bio-Cellulose Dome Diaphragms" are credited with producing the headphones' superclear treble and oh-so supple bass. The headphone also sported real lambskin-covered ear pads, and the … Read more

Can expensive audio cables improve the sound of a hi-fi?

Some audiophiles swear that cables can make or break the sound of their hi-fis, while others poo-poo the idea and use the cheapest hardware store wires. The debates have raged for years, but the only way to really know for sure is to try a set of high-end cables in your system. When I sold hi-fis for a living, I convinced a lot of reluctant customers to buy a set of cables, with the promise I'd refund their money if they didn't hear a difference. The majority of them kept the cables; even some of the most skeptical … Read more

A new high in high-end headphone amplifier design

The Fosgate Signature Headphone Amplifier is one of the very best-sounding amps I've ever used. It was designed by one of the greats, Jim Fosgate, a man who earned 18 audio related patents, founded a number of successful electronics companies -- oh, and he pioneered high-power car audio systems. He was also a big supporter of the very first home surround format -- quadraphonic -- in the early 1970s, and so committed to the format that even as quad was winding down, he designed the Fosgate Tate 101, arguably the finest quad processor of the era. Fosgate also created … Read more

Giant killer: ALO's tiny Pan Am headphone amplifier

Frankly, I was a little disappointed when I first unboxed the new ALO Pan Am tube headphone amp. It looked so cute and tiny; how could it possibly deliver the goods? The dainty 4.6-inch-by-3.8-inch footprint makes it easy to place anywhere. The amp's rear end houses three inputs: stereo RCA and 3.5mm analog inputs and a USB connection. The built-in digital-to-analog converter accommodates up to 24-bit/96-kHz audio. The amp is available in anodized silver or black finishes.

I started listening with my trusty Grado RS-1 headphones and loved the clarity. The Pan Am has the … Read more

JDS Labs' overachieving headphone amplifiers

John Seaber started JDS Labs in 2007 with the cMoyBB headphone amp, which is based on an open-source design. Seaber revamped the cMoy's power supply and volume control, added a DC power jack, and a special bass boost switch. The tiny amp sold well and got the company off the ground. The cMoyBB is still being made, in an Altoids tin box, and currently sells for $60. Seaber is 26 and has an electrical engineering degree from Missouri S&T University.

The JDS Labs Objective2 (02) sells for $144, and it's equally adept with full-size and in-ear … Read more

Headphone geekfest in Babylon, NY

Head-Fi is a national headphone club, and I went to the local meeting in Babylon, N.Y., last Saturday.

The vibe was friendly, and it was great to hear Head-Fi members' home-built gear, but there were a few surprises popping up from the headphone and electronics manufacturers in attendance.

Logitech Ultimate Ears' Personal Reference Monitor in-ear headphones feature a new twist on custom-molded-to-your-ears headphone design. Lots of brands now make custom in-ear headphones, and Logitech's have been among my favorites for years, but the upcoming Personal Reference Monitor takes the personalization to the next level. Once your ear canals' &… Read more

Heavy-metal thunder: The very best high-end audio products

I had a long fascination with high-end audio before I owned any of the good stuff. I suppose the same allure applies to exotic cars; millions read reviews of cars they never drive, and watch Food Network shows about food they'll never taste. Folks are interested in excellence, but compared to $200,000 cars or celebrity chefs' handiwork high-end audio is more accessible and practical. Two products covered in today's blog -- used high-end Grado headphones and the Oracle Delphi turntable -- sometimes sell for less than $1,000 on eBay. That's still expensive, but more within … Read more

The best headphones in the world?

I've written about the Audeze LCD-2 headphones in this blog before, but now I'm going to cover the LCD-3 model, Audeze's best headphones. At first glance the two don't look all that different, but the LCD-3s sport real zebrawood earcups and have thicker and softer real lambskin leather cushions to coddle your ears. This is a fairly heavy (550-gram) set of headphones, but they're comfortable to wear for hours at a time. Details of why the LCD-2s and LCD-3s sound different aren't forthcoming from Audeze, other than the drivers, which use similar technology, are … Read more

An extraordinary headphone amplifier from Red Wine Audio

Red Wine Audio makes some of my all-time favorite headphone amplifiers, but they're pretty expensive. The Isabellina HPA LFP-V Edition, for example, runs $2,500; it was designed and built in Vinnie Rossi's small factory in Durham, Conn. The Isabellina is more than just a headphone amp, it features a spectacularly good digital-to-analog converter and a hybrid transistor/vacuum tube audio amplifier. While the amp can be run off an AC power outlet, it sounds best powered by its built-in 25.6 volt Lithium Iron Phosphate battery pack. The battery can play for up to 10 hours, and … Read more
