The heart of the RC-1590MKII is a power supply equipped with a pair of toroidal transformers of the company's own design. These transformers are physically and electrically isolated with dedicated analog and digital supply voltage channels for all critical circuits due to foil capacitors with low ESR to eliminate unwanted distortion and extremely low levels of intrinsic interference.
There is no built-in Wi-Fi streamer in the model, but there is a Bluetooth receiver with AAC and aptX support and an Ethernet connector for connecting the device to the network. The digital part includes a DAC on ARM chips from Asahi Kasei with 32-bit/768 kHz parameters, capable of working with MCU files and supporting DSD and DOP streams. There is also a universal MM/MS phono corrector on board.

There is also a universal MM/MS phono corrector on board. As for the physical connectors, they include a full set of analog RCA and XLR inputs and outputs, as well as digital inputs – optical, coaxial and USB. The latter support streams with a bit depth of up to 32 bits and a sampling rate of up to 384 kHz.
