R2R-11 mk2

Real NOS discrete R-2R DAC design

Fully Discrete Transistors Headamp And Preamp All-In-One.

Output power rated at 3800 mW @25 ohm, driving most headphones easily.

4 fully discrete R-2R DA converters (2 per DA-8 board) implementing two push/pull decoders.

2 fully discrete native DSD decoders.

Fully discrete current signal transmission design.

32bit / PCM384K /DSD512 asynchronous transfer using the Amanero 384 usb input

The whole digital circuit is comprised of 3 CPLDs (programmable chips) supporting firmware update to improve sound quality in the future.
