Forty years ago, the Ohm F speaker was a game-changer; it still is

Lincoln Walsh died a year before his radically innovative speaker technology made its commercial debut in the Ohm Acoustics F in 1972. The speaker featured an omnidirectional Walsh driver that projected a massive stereo soundstage. At the time of its introduction the $900 per pair Ohm F was hailed as one of the greatest speakers of all time by the international press. It sounded like nothing else, and the single 12-inch, truncated cone driver produced bass, midrange and treble frequencies (37Hz to 17kHz). The driver had a titanium top section, aluminum midband and paper bottom, with a single voice-coil at … Read more

The overachieving TR-1D subwoofer from Gallo Acoustics

I'm not a big fan of really small subwoofers. Not that the little ones can't make deep bass -- the best of today's mini subs can deliver lots of low-end oomph, but the quality of the bass won't be anything to write home about. The bass is usually sloppy and poorly defined, so individual bass notes blur together. That's not such a big problem when reproducing the sound of explosions and special effects, but most small subs are less adept with music.

The Anthony Gallo Acoustics TR-1D ($599) sub is fairly small, but still handles … Read more

DTS headphone surround-sound technology

DTS demonstrated its new Headphone:X surround processing system at the Consumer Electronics Show in Las Vegas earlier this month. The system is capable of reproducing up to 11 channels of surround sound over conventional stereo headphones. I didn't hear it, but a few friends at the show who heard the Headphone:X demo came away impressed with its ability to project a sound field well outside the confines of the headphones. DTS is promoting Headphone:X technology as HTiP -- Home Theater in Pocket, and claims that the system can emulate the DTS reference listening room or a … Read more

Oppo BDP-105: Not your average Blu-ray player

Even by Oppo's high standards the BDP-105 is an extraordinary Blu-ray player. Sure, it's loaded with up-to-the-second features -- 4K upscaling, 2D-to-3D conversion, and a high-quality USB 2.0 digital-to-analog converter -- but what really makes the Oppo special is the sound. Pop the cover and look inside and you'll see why. Most of the 17-pound component's chassis space is devoted to the audio circuitry. That's nice, but the audio advantages will be completely irrelevant if you connect the BDP-105 to your receiver with a HDMI cable (the digital-to-analog conversion would then be handled in … Read more

Wowed by the Woo WA7 headphone amplifier

The Woo Audio WA7 Fireflies is one of the most beautiful audio products I've ever used. For my money it approaches a level of design grace comparable to that of Apple products. The 5-inch cube headphone amplifier has two vacuum tubes protected by a thick glass cover. The WA7 also has a built-in 32-bit/192kHz USB digital-to-analog converter (DAC) and lots of custom-made parts, including dedicated nickel alloy output transformers. There's a 6.3mm jack for home-style headphones, and a 3.5mm jack for portable ones. That's noteworthy, as few headphone amps have both jack sizes. The … Read more

How to buy a hi-fi

The first question is, what do you want from your hi-fi? Do you want to play LPs, CDs, or an occasional movie? Next, where will you put the speakers, and how large or small do they need to be? I'm writing this blog post for folks trying to put together the best-sounding hi-fi they can on a fixed budget. That's why I won't be covering wireless systems, because dollar for dollar, the better wired speakers always sound better than wireless models.

Setting the budget is the next logical step. I've written about an amazing-for-the-money $70 hi-fi system, … Read more

Recalibrate your expectations of how good an in-ear headphone can sound

I've been listening to Jerry Harvey's custom-molded in-ear headphones for years. The very first one, the UE10, was a game changer; in 2006 it was the best sounding in-ear headphone I'd heard. Now with his new Freqphase JH13 and JH16 in-ears, Harvey's done it again. The performance gains in clarity, detail, resolution, and stereo imaging are huge -- the adrenaline-pumping sound of the music you love over a set of Harvey's headphones can't be matched by any other in-ear 'phones.

Years before he made headphones, Harvey mixed stage monitor sound for Kiss, Van Halen, … Read more

A Kickstarter project promises crystal-clear-sounding speakers

Tech startup Coleridge Design Associates is trying to raise $45,000 on Kickstarter to manufacture a sleek-looking and transparent-sounding desktop speaker system, the aCube BMR. I've covered Kickstarter projects before, but this time I had a chance to listen to the product, and the sound definitely piqued my interest.

The aCube uses an advanced 4.5-inch BMR (Balanced Mode Radiator) driver mounted in handmade clear-cast acrylic 6.5-inch cube enclosures. The $180 speaker houses a stereo 20-watt Class-D amplifier, but if you want stereo sound, you have to buy a second speaker (without the amp) for $120. Optional at … Read more

New-to-vinyl converts talk about the joys of playing LPs

I've heard the naysayers for years, the ones that say vinyl is a fad, or that kids buy records just because they think LPs are cool. But the fact is vinyl sales keep going up year after year. I'd be the first to admit that playing an LP is more of a hassle than listening to Spotify, so why do people who grew up listening to CDs and files invest in a turntable, and search out their favorite music on LP? Why do they do it?

Recently, I talked with a few music lovers who grew up in … Read more

A headphone amp and USB digital-to-analog converter for just $99 each

Schiit Audio's very first product, the Asgard headphone amplifier, left me shaken and stirred back in 2010. It sold for $249, looked and sounded amazing, and to top things off, it was made in the U.S. -- not just assembled here. Most of the Asgard's parts are sourced from U.S. companies.

The Asgard is still in company's product line, and it's still $249. But Schiit has grown since then, and now offers a full line of more expensive headphone amps and USB digital-to-analog converters (DACs) -- which is great. But the company's most recent offerings sell for just $99 each! The Magni headphone amp and the Modi DAC are also made in America, and they sound spectacular. … Read more
