Denon, one of the world's leading manufacturers of high-quality home entertainment products, announces the availability of their first ever DA-10 audiophile portable headphone amplifier with USB-DAC. It features exclusive Denon technologies and state-of-the-art D/A conversion along with compatibility with high resolution audio file types, including up to 24 bit/192 kHz PCM and 2.8 and 5.6 MHz DSD audio files.

Targeted to audiophiles and serious music listeners, the DA-10 ($399) features Denon's purist approach to design and execution. It is housed in an elegant aluminum finished casing with a solid aluminum alloy volume knob, and includes a carry pouch designed to house the DA-10 as well as a portable audio device or a smartphone.

While portable audio players, smartphones, and tablets can easily power ordinary ear buds, their analog audio output stages typically can't handle higher impedance headphone types, and the quality of their internal D/A conversion isn't up to the standard that serious music listeners desire. That's where the DA-10 changes the game and takes over. With its advanced audio technologies engineered by Denon audio experts, the DA-10 brings all the details, all the bass, and all the excitement back to music. This is not only noticeable with high price audiophile headphones, but also easily noticeable with standard, yes even ordinary in-ear buds. The DA-10 also acts as an external DAC for an analog Hi-Fi system. Just add it to an existing Hi-Fi system and enjoy via the new digital connectivity of a digital music library with the best audio quality.

The DA-10 features state-of-the-art D/A conversion, using the reference class 32 bit/192 kHz Burr-Brown PCM-1795, which is usually found in premium audiophile disc players and digital amplifiers. The DAC features the ability to decode linear PCM files with sampling frequencies from 32 kHz all the way up to 192 kHz, and bit depths up to 24 bits. It is also compatible with one bit DSD files (the format found on SACD discs).

Internally, the DA-10 features premium Denon design and construction, with separate circuit boards for the main audio block and the power supply block, to eliminate inter-stage interference. There are dual master clocks (22.6 and 24.6 MHz) to optimize performance with specific sampling frequencies (44.1, 88.2, 176.4 MHz and 32, 48, 96, 192 kHz), and the low phase clock crystals are positioned directly adjacent to the DAC chip on the audio board for maximum jitter reduction.

Audio quality is further enhanced by Denon's exclusive digital filtering and noise shaping algorithm, Advanced AL32 Processing. This technology, found on Denon's premium disc players and premium digital audio separates, takes standard 16 bit digital audio and upsamples it to 32 bits, dramatically improving low-level resolution and high frequency detail. In addition, the technology also features dynamic digital filtering, optimizing the digital filter algorithm according to the specific sampling frequency of the track being played.

There are numerous inputs, including standard USB for iPod, iPhonea nd iPad, and micro-USB port for direct connection to a computer's USB audio output. This port works in asynchronous mode to support not only 192 kHz/24bits high-resolution audio but also the DSD 2.8MHz and 5.6MHz for maximized performance and the most direct way to enjoy excellent quality. For other portable devices and players, the DA-10 package also includes a standard 3.5mm-3.5mm stereo analog cable, with "L" connectors on both ends.

The DA-10 features multiple output modes. There's a dual position gain switch for low and high impedance headphone types, as well as a variable/fixed output switch that allows for direct connection to another audio component, such as a home stereo amplifier. Housed in an elegant aluminum finished casing, the DA-10 comes with a custom-designed carry pouch to protect the device and a phone while traveling. Further it combines the DAC and the phone to one handy device and covers all cables. Operation of the phone is still possible by a pliable see-through window.

Equipped with a high capacity (3200 mAh) rechargeable lithium-ion battery, the DA-10 provides up to 7 hours of run time with an iDevice, and up to 24 hours runtime when connected to a portable player via the analog 3.5mm input. The DA-10 lets the user know the battery level at turn-on by showing the charge LED in different colors.

With the Denon DA-10 portable USB-DAC and headphone amplifier, audiophiles and serious music listeners can enjoy hours of superb audio fidelity with their favorite portable devices virtually anywhere. It is expected to be available in stores and online in November.
