Acuhorn R2R, a tiny modern design that twins with the RATE amplifier. Just to get closer to the recovery of music playing as it was at the beginning. Today there is no better way for digital to analogue converter than to load to the programmable logic with as much computing power. To split the signal into millions of particles and unload onto a discrete ladder of analog resistors. It's like a stylus diamond traveling through a vinyl groove.
