AUDIO-GD has just annonced they will sell their first R2R DIY module, DA-M1.
As always the price is very tight :
29.8$ without resistor
43.8$ with 0.1% resistor
Summarize：
Applied programmable chip , up to 450MHz working frequency, offer strong ability and can through the codes to improve the performance.
Multiple modes built in for users select , it is better choice of DIYers.
1, It can setting working either NOS mode (IIS input) and after digital filter ( Right Justified ) so it can easy for DIY a new DAC or replace the DA chips in the original DAC .
2, It can setting working either left and right channels, the two DA modules just want to connect same IIS input signal and can working as stereo DAC without external process .
3, It can setting either invent and non invent , four pcs modules can connect same IIS input signal and working as balanced stereo DAC without external process .
4, It can setting working in Pull / Push mode as the PCM1704 technology, two module working for one output , one for the positive wave , another for the negative wave , refuse the zero distortion . Even though without Pull/ Push mode, only one pc working, the zero distortion is very low.
Built in 0.1% resistors and in parallel , as 0.05% tolerance .
Support up to 24 BIT / 3072Khz in NOS mode, and 384Khz in 8x oversampling mode.
Low Power Consumption, only need +3.3V (+/- 5%) / 30mA power.
I think it a good way to have a cheap R2R DAC and a good alternative to Soekris DAM1121
