AUDIO-GD DA-7 MKI 2023

R2R DAC Module 24Bit / 384kHz

AUDIO-GD DA-7 MKI 2023 Module Stand Alone DAC R2R 24Bit / 384kHz Mono

The Audio-GD DA-7 MKI 2023 features a 24-bit DAC based on a resistor network. It benefits from all the manufacturer's know-how when it comes to offering decoding via discrete components with high-frequency CPLD correction. This design feature significantly reduces distortion while keeping the price down (the logic circuit correction algorithm compensates for resistor tolerance).

This DAC module is capable of decoding up to 24bit 384KHz in NOS mode (without oversampling).
Integration with CPLD also enables native DSD decoding up to DSD512 if coupled with an Amanero or XMOS USB input interface.

For power supply, the module requires only +3.3V (+/- 5%) / 50mA.

This DIY version brings R2R High-End DAC technology in a discrete component to all uncompromising music lovers.

This is the 2023 version of the DA-7 MKI module (originally derived from the R2R Audio-GD R-7 DAC). It features an I2S input.
The output phase can be inverted to suit both balanced and unbalanced configurations.

This DAC module is sold alone, which means it doesn't integrate the output stage. Its supported sampling rate is 24bit 384kHz. To support a DSD512 input signal, you'll need to couple it to a USB Amanero or XMOS input interface.

Dedicated Class A power supply  

The module requires very little current to operate (+3.3V (+/- 5%) / 50mA). Audio-GD offers HiFi quality Class A power supplies for direct connection to the DA-7 MKI 2023. These ensure separation of the power supplies between the analog and digital circuits.

One or two power supplies can be connected to a pair of DA-7 MKI 2023s to create a symmetrical stereo DAC.

Its more my personal taste
I am doing a lot of DIY, the last DAC was based on an ES9038Pro in stereo. This one is different. I coupled it with a tube buffer and an XMOS interface, it worked with no issues and in my taste more musical than the ES. For the cost its a no-brainer.

Awesome!
Got it combined with the Amanero Combo768 interface (i2s). Sounds better than my Topping D30Pro.

Beats the sigma-delta bunch.
Formerly, i made a project with the ESS flagship ES9039 with reclocker, FIR reconstructor, etc, very ambitious. It was OK, the dynamics and clarity superb, but was a bit too... well over the top, so to speak.
I bought two of these R2R-boards, and just used them as replacements for the ESS chip. I had a multi bit DAC some 15 years, and since then I can't really be friends with the sigma delta types.
With these boards it's like coming home - but with the house freshly painted. The typical superb representation of nuances that renders poetry to the listening session is there. But it's even better than the old PCM1704 I had. These new boards have something the PCM1704 didn't have; a CPLD that cancels away resistor mismatch. This is the new brave DAC world. The old sigma delta devices, used for so many years, days are counted. In the future all audiophile DAC's will be this kind of intelligent R2R design, but probably packaged in one chip.

But the images of how to connect the boards are a bit misleading. The single ended OP-amp schematic is not very recommendable.

I'm giving it just four stars, since I don't really have something to campare it with, at least not other brands of the same type.

amazing
I built my own DAC based on this. It is an amazing piece, worthing every penny... If you can built a DAC use this R2R, unbeatable for price

this is brilliant
made a dac with 3 r2r bords and passive output without opamps ,tried with opamps it sounded dull and bad compared with my dddac, with passive output it beats ny dddac and my friends metrum pavane and a denafrips, they just got beated very bad, the psu used is a 3 stage psu with emi filters and lt3045 in the last stage, lm1084 in first stage and lf80 in second stage, and a lot af b4 15000uf caps in indput and before lt3045, this is the best dac i ever heard
