AK4499 is a flagship chip of AKM which adopts current output structure and 4 channels design, We parallel every 2 outputs to be one channel of D90 to get better performance. Due to the full balanced structure of D90, it can be balance output and single end at the same time. You can choose either of them and it’s more convenient to use with other devices
With the AK4499+XMOS, D90 supports up to 32bit/768kHz and DSD512 which far more exceeds the CD and SACD. Moreover, we customize the Thesycon driver for Win7 or above to get a better performance
D90 adopts CSR8675 chipset to support Bluetooth 5.0 and LDAC/AAC/SBC/APTX/APTX LL/APTX HD protocol. D90 could achieve 24bit 96kHz Hi-Res transmission with LDAC, the Bluetooth could have good sound performance from right on. If you do not need the Bluetooth input, you can completely turn it off in the menu
AK4118 is currently the lowest jitter of S/PDIF receiver, with the good compatibility, it is used for receiving OPT/COAX/AES that all support up to 24bit/192kHz. And D90 applies the CPLD, focusing on the clock processing and signal optimization. CPLD combines with the accusilicon femto-second to bring a lower jitter effect, while coordinates processing of digital signal optimization to improve signal quality and stability
D90 has various inputs such as AES/ USB/ OPT/ COAX/ IIS/ BT. USB and IIS input support 32bit/768kHz and DSD512. AES/OPT/COAX input support 24bit/192kHz. The BT supports 24bit/96kHz for LDAC. And IIS input can be set in the machine and is compatible with most IIS signal that uses HDMI transmission in the market.
