"A Hell of a Good Thing," Says Stereophile
The ADL GT40 from Alpha Design Labs is built for enthusiasts with growing music collections on their computer hard drives. It's a high performance 24-bit/96 kHz USB DAC that's amazingly affordable. Enjoy audio in high resolution at 96KHz/24-bits surpassing conventional 44.1KHz/16-bit standards for far better than CD-quality sound. Looking to convert your LPs or other analog sources to digital? The GT40 has built-in technology to take you there, plus an audiophile headphone stage.
The ADL GT40 received a top rating of Five Stars from England's What Hi-fi? magazine. "It's a real Swiss Army knife of a product – and it performs admirably. The on-board DAC is excellent." According to the magazine, "If this unit were judged solely on DAC performance it does enough for a five-star verdict. But it's way more than that…"
"A Loud Bravo is in Order!"
"The Alpha Design Labs-Furutech GT 40, like its maybe-namesake [the legendary Ford GT-40], is one of those things no one saw coming from any direction: a hell of a good thing," reports Art Dudley in Stereophile, September 15, 2011.
"From this point forward the GT40 is my new reference preamp recommendation below 10.000zł [$3,200] period," raves Wojciech Pacula in an April 2011 post for 6moons.com. "Considering price, a loud bravo is in order!"
Built-in Phono Stage for Archiving Vinyl
The seriously-shielded, audiophile-grade GT40 features a low-latency USB 2.0 audio driver that plays and records at 96 kHz. Looking to convert your LPs or other analog sources to digital? In a likely first for this category, the GT40 includes a built-in low-noise MM/MC phono preamp, too! That means you can connect your turntable directly to the GT40 without the need for an external phono stage or preamp with phono stage. Record your favorite vinyl to hard disk via the USB output. You'll find lots of software online to help you with this easy task, including free Audacity software.
You can use the GT40 to convert other analog sources to digital, too. It incorporates a high-performance analog-to-digital IC chip for high resolution recordings via analog inputs such as a tape deck, AM/FM radio, or the line-out jack of a portable music player.
Vivid, Captivating Sound Quality
The ADL GT40 features left and right analog outputs along with switchable line or phono inputs with a vivid, captivating sound that is simply unheard of in this category. The ADL GT40 (wired with Furutech's GT2 USB cable) brings Furutech's signature sound of smooth, detailed clarity to desktop systems, especially with high resolution 24-bits/96kHz files. But even 16-bit/44.1kHz files sound impeccable and very musical.
An external power supply gives the GT40 the edge over other USB DACs. While a USB-powered device might be convenient, it may not be able to develop the power required for high resolution playback. So ADL designed the GT40 with an external power supply to solve the problem.
Highest Quality Parts
The GT40 features a high quality amplifier and condenser supporting its high performance analog circuit. The GT40 is equipped with high-end, audiophile-grade gold-plated fluoropolymer-insulated RCA jacks. The GT40's casework consists of an extremely high quality aluminum chassis and machined volume knob.
Note: The GT40 has no setting for gain to match different impedance headphones. ADL recommends using 16 ohm to 300 ohm impedance headphones.

"The ADL's construction quality is superb. The chassis is one of those aluminum alloy extrusions that's cleverly made not to look like an extrusion, the faceplate is minimalist but well made, and the controls - especially the volume knob - feel downright luxurious."
