Hello Lucian,
I have the BuffaloIII up and running. Your Wave IO and the Buffalo III is a marriage made in heaven. Never heard a so detailled, transparant and dynamic sound. I'ts not a little step but a giant jump foreward in Sound quality.
Thanks Lucian for sharing this excellent product.
Kind regards,
Henri

@ Henry47: I'm glad it's working for you now and you're pleased about the SQ of your design!
@ robadenshi: I've updated my Diyaudio profile today for easier access to my email. Later on I'll send you PM with details.
Kind regards,
L

Pictures!
Henri,
Once I receive boards I will be doing the same, WaveIO to Buffalo III, can you provide pictures and any hints?
Have you tweaked the BIII in any way?
Thanks,
D.

Hi PET-240,
I attach a few pictures of my original build. I will rearrange the backplate with all inputs directly behind the 4*SPDIF board.
What I have learned building the DAC is : KEEP INPUT SIGNALS and cables AS SHORT AS POSSIBLE!
Although The combination WaveIO - BuffIII is excellent, the DAC is rather picky about input signals. So you should deliver it signals as clean as possible. But when all is ok, you got you a top class DAC.
kind regards,
Henri
ps.: The interconnection diagram just gives an idea how to place the modules. Connections are not entirely correct.

Hello gabanyayaya,
coincidently or not, now I'm answering to your request! Please give me few minutes to finish it.

Henri, I can't be sure but it looks as though there is some difference in length of the i2s lines, I think matching length of these wires may be of similar importance to minimising the length, just a thought. Very nice work otherwise!!
A question I have been meaning to ask for a while now. Is it possible to drive one i2s dac from the u.fl connectors and a separate DAC from isol i2s output at same time without damaging/having visits from the nasty blue smoke monsters?

Hey Lucian,
Is there a thought to make the wave do 384kHz or dsd? Not that I have any at that sample rate.....just curiosity....!
Thanks,

The usb to i2s board got a +5V pin at the Isolated I2S Outputs. Where do you connect this terminal for connection with PCM1794 chip ? Will it works if I ignore this connection ?
Regards
I have used only 2 power regulators, +5V for all the digital section and +5v VANA for the analog section.
From the picture I see 5v pin (of the usb to i2s card) is connected to Vdd of the pcm1794. I this necessary when 5v psu is connected to the converter ?
Thanks for the photo. You made your point now when all 5v terminal needs to be connected.
If you want to isolate the ground of the USB-I2S module use a different power supply for this.
It means another transformer secondary, another bridge, another CRC and another LT1086.
In this case the heatsink is necessary only for the LT1086 connected to the USB-I2S module.

The ground isolation should be better but ......
How to be sure that the two different gnd does not exceed the maximum voltage allowed by IL715, 2500 VRMS Isolation for 1 min. ?
How to connect the 2 power supply gnd to the chassie for the screen ? probably the solution is use only a cap. instead of 100 ohm resistor
Have someone build a comparison test with coax output and IL715 outputs ?
Now I don't know where buy coax cables to use the other outputs.

Yes, there are thoughts but if WaveIO will have these features or not, time will tell... If there any chances though, then I'll do my best for these features to be implemented; if not, I would prefer to be silent 🙂
mBNC receptacles (U.FL) used for WaveIO can be found here while coax cables here.
Kind regards,

I've just received Lucian's board.
First thing to say is about Lucian, a very kind person, and then, excellent packaging and quick shipping. The card manufacturing is of high quality, professional, I'd say.
My actual setup is based on: AsusF5VL-VistaHP notebook, flac library on external usb hd, foobar 1.1.11 with soX output @96k, std 3m usb cable, externally powered (7808 linear ps) Teralink X2 feeding a TP Opus 8740 via non-isolated I2S.
WaveIO will replace X2 from tomorrow on.
