R-7 (2021 Version)
　

8 group fully discrete R-2R DA modules to combine into real balanced push/pull decoders.

4 group fully discrete real balanced DSD native decoders.

Fully discrete real balanced current transmition design.

2 pc ultra high frequency 90/98 MHz Accusilicon 318B femtosecond clocks provide synchronous clock for whole unit without PLL up-frequency .

32bit / PCM384K /DSD512 asynchronous transfer Amanero 384 apply the FPGA synchronous clock.

Both USB / HDMI have built in separate isolator and pure class A isolate power supply.

The whole digital circuit built with 1 pc FPGA and 7 pc CPLD programmable chipsets to separate the different configured circuits for avoid interrupt, data process in parallel mode.

Support firmware update to improve on sound quality.

Input signal sampling display.

Support external 10MHz clock input (Default is 50 ohm, 75 ohm can be custom order).

All digital process mode settings accessible by buttons on front (No need to open the chassis).

Firmware update port accessible on rear (Update firmware no need to open the chassis).

Specifications tested by OS8 mode , we always improve for better real like , musical and analog sound ,improvement may result in changes in specifications and design without notice.
