Several forum members and exaU2I users have asked me to produce a modified version of exaU2I for use with PCM1704. A good solution will require two changes to the current device:
I wonder how many of you are using PCM1704 and would be interested to preorder?
- Change in the output format
- Elimination of GMR jitter

Hi, Personnaly I would be very interested in a version of your exa device with 8 output channel of 44100hz PCM or I2S and linux support ( ALSA linux developpers would help you if you contacted them).
And yes I could be interested in PCM1704 but if on a seperate board because I am interested in 8 channel of output meaning several PCM 1704 (probably also in balanced fashion).

I want to use Windows Media Player Classic to play movies.
Windows Media Player classic has no ASIO support, but i heard of people using Reclock. Can anyone confirm if this is actually working in combination with the EXA device and windows 7 ?

The modified exaU2I will be only an interface. The DAC board will be separate. You will be able to connect up to 8 channels and of course you will be able to implement balanced mode PCM 1704.
egberttheone, can you provide more information about the Reclock configuration that you want to implement. I will test it and I will publish the results. I am not familiar with Reclock so I will need some guidance from you.
I don't think anyone will decline this added functionality. As there will be a slight redesign of the board i wonder if a provision for external power instead of USB-derived will be possible via jumper/pad.
Hi exa, i have some q if You dont mind...
1. Does it Mac OSX supported?
2. Does the hardware accept difital USB galvaniv isolation
but on the input (with adum4160...)
{I know that one iso barrier exist at the outputs it is clear from the picture...}
3. is there some posibility to have split I2S bus L/L and R/R ?
thanks
cheers

If there will be a PCB upgrade is it possible to add a header / jumpers between the USB connector and the USB hardware parts for 5 volt, gnd, and the D+ and D- signals for easy implementation of USB isolation?
RayCtech, I am not sure if this is a good idea. The new board will deal with galvanic isolation in a different way. There will be no need to isolate the USB input.
Hi Zoran,
For now there is no OS X support. Could you explain in more detail questions 2 and 3? How do you want to use the L/L R/R I2S output?
Cheers,
Exa065
Then it will be interesting to experience how the new galvanic isolation performs.
This is correct, the ASIO input can be configured as L/L R/R or any combination of any channels.
Now I am running "glue logic" I2S splitter to L and R ch
(to feed dual mono sabre)
to be more clear
data order:
normal I2S = 32bit_left-data - 32bit_right-data - 32bit_left-data - 32bit_right-data
I2S left = 32bit_left-data 32bit_left-data
I2S right = 32bit_right-data 32bit_right-data
(sys clk and latch remains the same...)
I think that should not be hard because the datas are alredy in memory
just to "repack" the order of words?
😀

you dont need to do this with sabre, if you have mcu anyway. you send the same single i2s stream to both dac chips, but there is 2 addresses available for this purpose to set channels
I search the datasheet and didnt find such a option?😱
(9008 model)
could You post the addresses and datas to write in please?
