The Audiolab D7 features four S/PDIF inputs – two coaxial and two optical, a USB HDD input for playback from external flash drives, and a USB type-B input for PC, Mac, smartphones or tablets. It also features coaxial, optical or analog RCA outputs and fully balanced XLR outputs, making it a versatile digital audio hub. Bluetooth reception is also provided, with support for multiple codecs including apex HD, and support for the Bluetooth 5.1 standard for optimal range and speed.
The next generation 32-bit Sabre chip, the ES9038Q2M, is the benchmark in DAC standards. However, when combined with a proprietary circuit that makes the most of the ESS HyperStream II architecture and a time domain jitter remover to deliver ultra-low noise and high dynamic range, Audiolab engineers have a proven track record of implementing this chip to create class-leading digital audio converters.
The Audiolab D7 supports high-resolution audio with support for DSD up to 22.5792 MHz (DSD512) and 32-bit/768 kHz PCM via USB or 24-bit/192 kHz PCM via S/PDIF (optical and coaxial). It is also a full MQA decoder, with the full three-unwrapping decoding process performed internally, rather than just the final unwrapping as in an MQA renderer.
Users can increase the sampling frequency of digital audio signals to 352.8 kHz or 384 kHz. With specially designed DAC reconstruction filter settings, the Audiolab D7 offers five performance settings to suit the source files or system components. This nuance will be very useful given the huge variety of supported digital file formats, not to mention users of headphones or digital streaming services.
The Audiolab D7 features a powerful headphone amplifier with a current feedback circuit, making it even more versatile. Like the Audiolab 7000A, this solution is designed for all types of headphones and provides exceptional clarity and drive.
