The Fosi Audio K7 is a compact, high-performance DAC/headphone amplifier featuring an original design and high-quality components. It features an XMOS XU208 USB interface, an AKM AK4493SEQ DAC chip for its digital-to-analog conversion stage, and a balanced amplifier circuit with two TPA6120 chips and OPA1612 OPAs. The Fosi Audio K7 is therefore capable of supporting high-resolution audio streams up to PCM 32bit 384kHz and DSD256, and delivers headphone output power of up to 2x 2100mW at 32Ω. The K7's Bluetooth 5.0 connectivity - thanks to a Qualcomm QCC3031 chip - supports standard SBC and AAC codecs as well as the high-resolution aptX, aptX LL and aptX HD codecs, and thus offers a quality wireless listening experience. In terms of connectivity, the K7 is equally complete and versatile, with three digital inputs (USB-C, coaxial and Toslink optical), two headphone outputs (single-ended 3.5mm jack and balanced 4.4mm jack), as well as a 3.5mm jack microphone input and an RCA line output. Finally, a 1.5” LCD screen displays operating information for intuitive operation.
