Would you guys think this would be a must for any S/PDIF DAC? I2S requires 3 lines minimum, which is a lot for equipment interconnection if you were to transmit via 75 ohm coax.

i'm not sure I understand what you mean. transmit what by 75ohm coax? and from where? its supposed to be installed in your dac. you would never transmit i2s by 75ohm coax, it should be 50ohms, you havent noticed the tiny u.fl micro BNC connectors and cables the fifo uses?

well put it this way, if you must persist in sticking with spdif, then this is a really good leveler and for the money its a steal, dacs that come with this sort of system run to 5 figures

Default Connecting to Buffallo III

One is the input adapter. I put a 20P SMT head on the bottom side to get connect with B III, on the top side, there is a group of U.FL connectors which could improve the signal quality. For stereo I2S aplication, only three U.FL socket are required. Because at the sync mode, ESS9018 still very sensitive to the input I2S sck, improving the signal transmitting quality is very important.

The other one is the local clock adapter. It will be soldered vertically right above the local clock position by a right angle 3P connector pins. If you put a local XO (make use of the 100Mhz CCHD950 for example) into the socket, ESS9018 will run at async mode. or, If you want to run the sync mode, you just need to remove the local XO from the socket and connect the MCLK cable from FIFO clock board into the U.FL socket on the adapter PCB. So, you can switch between the two mode quickly to enjoy both, or doing some listing compare.

Good day, Ian!

I followed this thread with highest intrest though I understand the material just globally.
I own the Buff III as well and thriving for the best quality in using this DAC, I
like to use the Fifo and the double clockboard. My TP-Buffalo III setup exist of the four inputs SPidf module plus the sidecar, for switching between I2s and SPdif material. Next to this I use the Waveio USB-I2s card for playing Wav and Flac files from PC.
Can I just place the Fifo+clock between the output of the 4*Spidf board and the Dac? (for SPdif) And and (for the I2s connections) from the sidecar to the I2s connections of the Fifo to the I2s input of the Dac?
Or should I forget the sidecar and can I use both I2s an SPidf connections from the Fifo? And can I choose on the Fifo for both types of inputs?
Is it possible to use your SPdif-board in conjunction with the buffalo 4*input board?
Sorry, lots of questions, hopefully a simple answer,
Thank you for all your fantastic work!
Ed

Hi Ed.
Basically FIFO is I2S in and i2S out, while with S/PDIF buard will be S/PDIFs in and I2S out. Anything under is condition is OK. I'm using the second configuration. I don't have the sidecar of the 4*SPDIF board. I suspect the 4*SPDIF boad could go before the spdif board. But the spdif board already have three spdif input .
Have a good night
Ian

Hi Ian

I have exactly the same configuration as Ed except I don't have the 4*S/PDIF. I still can't figure out how to connect FIFO and WaveIO to the BIII and switching between them. according to qusp, the sidecar is not a good choice for switching I2S signal. Can you give me some suggestion?

Curiosity, would you not feed the WaveIO into the FIFO into the B III?

I have an Alix board running mpdpup Linux feeding the Wave which is planned to then feed FIFO to B III.

I am also trying to figure out the switching I2S. Ian have you any thoughts?

The FIFO doesn't have the extra I2S input for external device such as WaveIO. I am thinking of using Ian's 2 * BIII adaptor board + sidecar for I2S switching.

So you want SPDIF and USB input?

Of course, that's why I purchase the waveIO.
