ADL

The legendary and groundbreaking ADL GT40, known throughout the world as “the Swiss Army knife of audio components” when it was introduced, revolutionized the home entertainment industry when it came to managing computer-based music systems. The new and innovative ADL STRATOS, however, is set to raise the bar even higher with more features and even better performance.

The ADL STRATOS is more than just a DAC, a phono stage and a headphone amplifier in one small, portable box. With the STRATOS you get DSD (2.8M, 5.6M and 11.2M), USB (supports PCM 24~32bit/384kHz Max.) and ADC (24bit/192 kHz Max.), so you’ll be able manage the largest music collections on your hard drive with ease and flexibility—and outstanding sound quality.

If you need to convert your LPs or other analog sources to digital or record internet streamed audio, the STRATOS offers a wide variety of options to help you obtain the best sonic results. With its low-latency USB 2.0 audio driver that plays at 384 kHz and records at 192 kHz and its built-in high-performance MM/MC phono stage, you can easily record your favorite albums to hard disk via USB. Best of all, you’ll enjoy Furutech’s signature sound—detailed, clear yet smooth—when you use the ADL STRATOS as the heart and soul of nearly any desktop system.

If you’re looking for a powerful headphone amplifier that can drive any pair of headphones on the market, the STRATOS delivers. Whether you use the latest generation of ear phones or the most revealing electrostatic ear speakers available, the ADL STRATOS will allow you to venture and explore deeper into the recording than ever before. That’s because every product from ADL is built with only the finest materials, as well as the most innovative Japanese design principles. The STRATOS may be small, but it contains an amazing amount of technology.

Additional features include L/R analog inputs, line or phono (switchable MM/MC) inputs, S/PDIF Coaxial and Optical inputs, S/PDIF Optical output (for USB, Optical, Coaxial) and a controller that supports both ASIO and Asynchronous modes. The STRATOS also uses the finest Furutech connectors to deliver high-quality sonic results. Indeed, the STRATOS is far more than a classic GT40 with DSD capabilities—every square inch of the STRATOS has been reconsidered and rethought using the latest technology and the latest designs.

The original GT40 certainly shook up the audio world when it redefined the level of audio performance, flexibility and features available at its affordable price. With the ADL STRATOS, however, a new revolution has begun. It certainly qualifies as more than a new “Swiss Army knife of audio components.” It’s a whole new way of thinking.
