Underwood Hifi is glad to be selling Audio GD products. Audio GD is a 17 year old
Chinese company that produces state of the art products at
affordable prices. Reviews all their products have been excellent.

We
ship from stock out of our
Georgia warehouse. We also service the product in Georgia.

Probably
the best value of the Audio GD DAC's, the new 2021 R8 MK2 upgrades the
original R8 from 2018 that received great press.  It is a PCM/DSD FPGA controlled ladder DAC that is
90% as good as the best at a value price. It is even better when run
thru an Audio GD preamp with ACSS buss. Parts and build quality are world class.

 

At under $2,000 this is easily the DAC to beat. It clearly outperformed the PS Direct Stream that we compared it to. We know of nothing as good for close to this price.

USB & IIS : 44.1kHz - 384kHz /32Bit DSD64-512
Coaxial mode: 44.1kHz - 192kHz
Optical mode: 44.1kHz - 96kHz



R-8 MK2 features:

            -Thanks to the fully programmable circuits of the R-8, the firmware is upgradable to improve the sonics.

           -Fully balanced XLR, RCA and ACSS (CAST) connectivity

          - The improvement is quite obvious compared to the previous generation.
The R8 MK2 uses the newly designed discrete servo stabilized
power supply to feed the DAC circuits. In the new DAC the noise level is
now comparable to that of a battery, but without the dry and thin sound
characteristics of it, and thus the product's operating temperature is
significantly lower than that of the previous model.
       - The analog circuit
are still powered by a pure class-A regulated power supply for the best
sonic results.
This new R8 MK2 outperforms the older top of the line R7.

         1. Fully discrete parts are used in a truly balanced current
transmission design. Four sets of fully discrete and independent DSD
hardware decoders and eight sets of fully discrete R2R DAC modules are
used to form a two-channel fully balanced push-pull decoder.

          2. By listening to a turntable and studying its sound for a
long time, Audio GD has successfully integrated an analog vinyl sound
characteristic into the DAC. This tonal balance is optional and
controlled through the front panel. This is a new feature.

          3. Both the USB and HDMI inputs are equipped with opto
isolators, and two sets of linear power supplies to separately supply
power to the USB and HDMI modules before the isolators to prevent
interference from signal sources. The USB input uses a two-way
transmission isolator, which not only transmits IIS signals to the FPGA
processor, but also receives the synchronous clock signal sent by the
FPGA processor.

        4. The MK2 now has a display of the input signal sampling rate function.

        5. The digital circuits of the whole DAC are comprised of 1 FPGA
and 5 CPLDs (both programmable devices), which allow separating the
different functional circuits and preventing interference. The FPGA
operates using the parallel data processing mode. The parallel mode only
needs one clock to transmit and process the 32-bit data of the left and
right channels, which greatly improves the processing speed and is less
affected by the stability of the clock.

       6. Two superb Accusilicon Femto clocks provide synchronization
for the whole unit, and they are applied to the playback of all data
rates without PLL up-conversion. The clock management design of the new
architecture makes the clock more stable, which brings a more
transparent and detailed presentation.

        7. DSD uses the built-in asynchronous clock to enhance timing,
which  improves the clarity and dynamics of reproduction.

        8. SPDIF supports DOP playback.

        9. All digital mode settings can be changed on the front panel live.

       10. A firmware upgrade port is on the rear panel so there is no need to open the cover to upgrade the firmware.

Compare this DAC to anything we have heard under $4000.00-$5000.00.
