What is it?
The Denon DA-10 Portable USB-DAC Headphones Amplifier is designed to deliver sonic performance on par with separate premium audiophile components. The unit comes in a compact package equipped with a high capacity 3200 mAh rechargeable lithium-ion battery that provides hours of listening enjoyment anywhere on-the-go.
Housed in an aluminum chassis with a solid aluminum alloy volume knob, the unit features state-of-the-art digital-to-analog conversion using the reference class Burr-Brown PCM-1795 32-bit high resolution DAC chip, which can handle multiple sampling frequencies all the way up to 192 kHz, and bit depths up to 24 bits. The combination DAC and headphone amplifier is also able to decode high resolution DSD audio tracks (the type found on SACDs) at both 2.8 and 5.6 MHz.
The DA-10 features audiophile-grade construction, including dual master clock crystals, each optimized for specific sampling frequencies and located directly adjacent to the DAC chip on the audio board for maximum jitter reduction. The digital section features asynchronous USB signal handling, and there are individual circuit cards for the digital audio block and the power supply block to prevent inter-stage interference.
The company’s exclusive AL32 technology uses proprietary DSP digital filtering, upsampling and processing algorithms to upconvert and noise-shape high resolution digital audio to 32 bits, delivering improved low level detail and less distortion.
The device comes with multiple connection cables for compatibility with a wide range of portable music players and smartphones. The USB-30 pin cable is compatible with many Apple devices, including iPod, iPod touch, iPhone; and iPad. The USB-Lightning cable is compatible with newer Apple devices, such as iPhone 5 and 6, iPad Air, and other models that are equipped with the Lighting connector.
How does it work?
The integrated high capacity 3200 mAh rechargeable lithium ion battery delivers up to 7.5 hours continuous operation when connected to your portable music player or smartphone via USB. The multi-function LED battery indicator lets you know the current battery charge level at turn-on. When the battery is between 50% and 100%, it blinks green. When the battery level drops to between 20% and 49%, the LED blinks orange, and when the level drops to below 20%, the LED changes to red, indicating it’s time to recharge.
When connected to a portable player via the 3.5mm port, the battery life can be up to 32 hours. Recharge time can be as short as 3.5 hours, when connected to a USB charger with 1.5A output, or 6.5 hours when connected to a PC’s USB port.
The amplifier features an advanced analog output stage that is equipped to handle a wide range of headphone types, including premium audiophile and studio headphone models that often feature low impedance ratings, requiring more power from the output stage.
A side-mounted gain switch lets you adjust the output stage’s gain to precisely match the needs of your favorite headphones, including low impedance models, and the final analog audio stage features a discrete current buffer circuit. There’s also the option for fixed output for connection to an external audio system.
There’s also a USB-micro “B” connector for compatibility with other smart devices, and we also include a 3.5mm-3.5mm stereo analog cable for connection to a player’s headphone output, and the cable features L-shaped plugs for a secure connection.
