It is a truly balanced design, with a DAC and amplifier carefully paired for the left and right channels each, for the purest sound possible. With two high-performance AK4377A DACs, the power output has increased by 50% compared to the AK4376 used in the BTR3K as well as greatly improved measurements and actual sound. Distortion -107dB | S/N Ratio 122dB | Output power balanced 78mW | Output power SE 25mW. The Qualcomm CSR8675 Bluetooth chip used in the BTR3K is a premium low-power solution designed for enhanced audio applications, with a 120 MHz DSP, support for 24-bit transmission and processing as well as abilities to decode multiple lossless Bluetooth codecs. Support for the AAC/SBC/aptX/aptX LL/aptX HD/LDAC audio formats ensures that you’ll get the best sound quality possible from the BTR3K. The dual crystal oscillator system in the BTR5 also comes to the BTR3K! The 22.5792M/24.576 MHz dual crystal oscillators mean that during Bluetooth and USB decoding, the BTR3K can more accurately reproduce audio signals under various sampling rates – due to greatly reduced jitter and greatly increased audio stability.
