R-27  (2021 Version)
Built in real balanced pure class A headamp & preamp
Pure class A power 9000mW@40ohm
Dual gain modes can drive high/low sensitivity headphones

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 isolate power supply.

The whole digital circuit built with 1 pc FPGA and 5 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.

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).

  

       
Please note: The product improve cause the inside or outside change without inform .

Custom order options:

Option 1:Custom order replace the ACSS output by RCA outputs USD7.5.

Option 2: Custom order High Gain model for the HE6 and low sensitivity headphones:
      The unit default had 12DB on low gain for drive the headphone which has over 95DB sensitivity, and 22DB on high gain, already enough to drive the HE6 which has around 85DB sensitivity headphones.
