Project space for the my DIY R-2R dual-mono DAC project, comprising of two Soekris dam1021 Rev 4 (0.012% resistor version) DAC boards, dual independent AC power supplies, and an Amanero Combo384 USB to I2C Module
Project is going to be done in phases, so reduce cost in case I don't like the sound, etc.
However, due to shipping costs and delivery times, some items may have to be purchased together.
There are 3 main phases that I envision:
hase 1::
Without going into too much expense, I want to set-up a single Soekris dam1021 Rev 4 (0.012% resistor version) DAC board, with the intended 'audiophile grade' toroidal transformer, and the Amanero Combo384 USB to I2C Module.
Components:
:hase 2::
Building on Phase 1, now adding components for dual mono design, with separated and independent power supplies.

There are 3 main phases that I envision:
- Phase 1: Getting a 'taste' of the sound offered, and if it works for me compared to an of-the-shelf product
- Phase 2: Getting the dual-mono of the sound, and again checking if it works for me compared to an of-the-shelf product
- Phase 3: Getting a display and interface for the DAC.
