The Singxer F-1 is a fairly widely known and highly regarded USB Digital Interface Board with the XMOS XU208 chip and it comes with a SPDIF output by RCA jack already mounted on the board and ready to go right out of the box. It was originally only available as a bare board, but a Singxer sourced clamshell case has since become available separately for it, and the F-1 is also now available available already installed in the case.
The sound quality of the F-1, in comparison to the older XMOS chip based designs, is a more immediate and clearly defined sense of the individuality and acoustical space around each instrument and voice in the recording, as well as a much tighter and seemingly deeper bass response.
The Singxer C-1 is a USB Digital Interface Board with the XMOS XU208 chip is essentially a Singxer F-1 design that is intended for hardwired connection directly to an I2S port. It is available from kitsunehifi.com fitted with either Femto AS318B Accusilicon clocks at $124.99, or with NDK / Epson clocks at $112.99. The C-1 boards are in short supply as most of the Singxer production is going into trying to keep up with the demand for F-1 boards and SU-1 units. I have had disappointing experiences with the China sales sources for Singxer, but good experience with kitsunehifi.com. I believe that kitsunehifi is the only Singxer fully factory authorized distributor in the USA.
I have a Singxer C-1 that I want to install inside my Eastern Electric Tube DAC Supreme, replacing the stock (older XMOS chip based) USB digital interface board inside. Eastern Electric documentation of the stock card pinout configuration is not consistent with the Singxer C-1 pinout configuration, and I am concerned that there may be some errors in translation.
I would appreciate it if other DIYers would check my following table of possible pinout matches to see if I have them correct, and suggest corrections if needed.
EE DAC Board→ Singxer C1 Board
MUTE : → 4 - AUDIO_MUTE
GND : → 1, 3, 6, 8, 10, 15 - UGND
X34 :→ 14 - FS0
DSD DSD out :→ 12 - DSD 64/128
X53 :→ 16 - FS1
X55 :→ 18 - FS2
GND :→ 1, 3, 6, 8, 10, 15 - UGND
LRCK : → 9 - IIS LRCK
DATA :→ 5 - IIS DOUT
BCK : → 7 - IIS BCLK
MCLK :→ 11 - MCLK OUT2
SEL : → 13 - DSD ON
SPDIF : → 2 - SPDIF_TX
GND :→ 1, 3, 6, 8, 10, 15 - UGND
MCLK1 :→ MCLK in
+5V :→ no connection ( 3.3V at pins 17 , 19)

Did you ever do this mod? I have the same DAC and have looked at doing the same thing.
