Underwood Hifi is glad to be selling Audio GD products. Audio GD is a 20 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.
The R1 is an R2R full discrete DAC that uses 8 groups fully discrete R-2R DA
modules to combine into a real balanced push/pull decoder. It also uses 4
groups of fully discrete real balanced DSD native decoders.
It uses a fully discrete real balanced current transmission design. Jitter is kept ultra
low by using dual ultra high frequency femto clocks.
In the new review in headfi.guru they say: "To
say that the Audio-gd R2R-1 met all expectations would be an
understatement, in terms of musicality, accuracy, soundstage, detail,
timbre, noise floor, and resolution, it is one of the finest DACs I have
I were starting out from scratch and needed to purchase a DAC and
Headphone Amplifier combination, this would be my choice, not to
belittle my current reference gear, which I love, the Audio-gd gear is
just that good".

The R1 works up to 32bit/384K with
DSD512 asynchronous USB transfer thru the Amanero 384 FPGA synchronous
clock. The entire digital circuit is built with single FPGA and 5
CPLD programmable chip sets to separate the different configured circuits
to avoid interrupting the data stream process in parallel mode.
unit supports firmware updates future sound quality updates and all
digital process mode settings are accessible by buttons on the front.
In an R2R ladder DAC the unit switches resistors in parallel mode. An ultra-fast FPGA
controls and corrects the R2R ladder. This parallel design mode controls every bit
respectively and therefore achieves unprecedented performance. In
parallel mode only 1 clock cycle is needed to output all the data so
sonics are improved and the output is more analog like. After
the D/A conversion by the R2R D/A modules the analog signal is
transported by fully discrete matched-transistor output stages. The
R1 DAC uses high quality low noise, low flux leakage, R-cores
transformers to supply all digital parts and the left and right analog
boards. There are in total 13 ultra-high speed and ultra-low noise power
supplies built in and double stage Power supply technologies are used to remove
power supply voltage fluctuations.
Compare this DAC to anything we have heard under $2000.00-$2500.00.
