Using I2S With the Denafrips Terminator and Metrum Ambre?


Hello All,

I recently got the Metrum Ambre to connect via I2S to my Denafrips Terminator Dac. I tried both ethernet type I2S inputs, even trying the mode button with no luck. Has anyone out there have the same situation and gotten the two to play nice together? Maybe the cable has to be modified.  I tried reaching out to Metrum and no response after 4 days.

thanks  alvin! I started looking into it more. It looks like if I use the I2S "C" input and swap 3 wires, it will match the ambre. I just ordered an ethernet breakout board from amazon to test. if it works I will have a custom 12" cable made.
Anyone know who would make a custom RJ45 Ethernet cable for I2S for a reasonable price?
I have the Ambre working with the terminator. Using a breakout board, I tested it and worked like a charm, then I made a cable and it also worked fine. If anyone wants the pin swaps I will post next week as I'm on vacation and dont remember the exact pin swaps.
I would also recommend using a ethernet breakout board 1st to test. Much easier to work with then terminating cables. That's what i did. Amazon sells many different ones, I got this one.

I was able to get it to work with the following pin swaps. check the pin swaps on both devices and if you know how to terminate an ethernet cable you can make your own like i did. Here is what it had to do to make it work. 

Ambre to terminator
Pin 1 to 3   (gnd Pin 2 to 4)
Pin 3 to 7   (gnd Pin 4 to 8)
Pin 7 to 1   (gnd Pin 8 to 2)

Pin 5 stays the same. I would also recommend crossing the paired grounds in () as well. That's what i did and works great. The i2s connection is more transparent, bigger soundstage and more detail. The only negative and it's really not a negative is the level is lower, so I have to put the volume higher to achieve the same level as i did with spdif.
@alvin1118 Alvin, can you or anyone recommend a good footer replacement for the Terminator? I'm not crazy about the two piece spiked feet, especially for the weight of this Dac. One mistake, and anything under the terminator will get a nice scratch. I would like to go to a one piece footer solution.
