Flagship achievement flagship
D90LE uses ESS SABRE ES9038PRO, with 32bit Hyperstream architecture, achieves ultra-high performance in the audio field. Each channel of the D90LE will be arranged in parallel by 4 conventional balanced channels. This makes the performance of D90LE even better.
Bluetooth 5.0 LDAC transmission
D90LE has the certification of Hi-Res Audio Wireless and LDAC. It uses CSR8675 chipset to support LDACIAAC/SBC/APTX/APTX LL/APTX HD protocol.To get even better sound quality from Bluetooth, we abandon the built-in DAC of CSR8675 and connect it'sdigital signal to ES9038PRO to decode. We use CPLD to process the clock and greatly optimize the digital signal, so that regardless of USB, optical, coaxial, AES input, Jitter is lower than -160dB .
Preamplifier function
In addition to the DAC mode with a fixed output level, theD90LE also has a DAC+ preamplifier mode.In this mode, you can control the output volume on the front panel or at the remote control. This will provide great convenience when connected to a power amplifier or monitor speakers.And also help you leave the budget of a preamplifier. Turn your PC into a HIFI source: D90LE uses 2nd generation XMOS, USB supports up to PCM32bit768kHz and DSD512 native.
Selectable output
D90LE has balanced XLR output and single ended RCA output. You can choose "XLR only", “RCA only" or "XLR+ RCA" output to for different applications.
Sound simulation
According to the unique harmonic performance of tubes and transistors, we added the sound simulation function of tubes and transistors to the D90LE,so that you can hear 3 different performance.
