As an exaU2I owner, i dont used DSD, because I dont know much about it, maybe I'll use it in the future, but only if it becomes a reliable source for high quality STEREO sound.
My immediate interest is in finding a dac that can utilise the 352.8Khz capability of the U2I.
(even if there are no files yet)

  • Short term - develop alternative ASIO driver or enable alternative mode for the current driver. This solution will benefit current exaU2I users
  • Develop alternative FPGA implementation / diver - this option is justified if there is enough interest in the DSD playback capability
Additionally, there must be an ASIO player capable of DSD playback. The first thing that comes to mind is a Foobar plug-in. There is a plug-in out there capable of near-real-time DSD->PCM conversion. I will contact the developer to see if he is interested to alter the existing plug-in for native DSD output.
I think the only software for playing DSD on a Windows PC is Korg's AudioGate. Sony also has a DSD Direct Player, but it may only install on certain Vaio laptops.

Default Native dsd playback comments

Hello George

I mailed you my code June 15 at 17:26 (GMT + 2hours). Take a look in your spam filer.
I attached a zip file renamed to zi_

And back to why i will like native dsd support.

I have ripped my 700+ sacds to dff files, and will like to have the possiblity to play them in the native format, and on my main system as I can on my Korg MR2/JH16Pro portable system.
At the momemt I use the foobar2000 pluging and resample to 176.4kHz.
I am not aware og any windows player except professionel daw's (10000$++) that can play native dsd. They all downsample.
Last Time I looked Foobar2000 only supported sample frequencies up to 1000kHz in the main core. DSD is wav with a one bit wordlength, so in principle it is just to increase the max sample frequency

Until now it has been difficult to rip sacd's, but now there is a simpler solution using a PS3:
SACD ripping using your PS3 (part 2) | Computer Audiophile

So I think more people will have access to dsd/dff files, when they start ripping their sacds : there are 7000+ sacd made but how many 352.4kHz files is it posible to buy.

To comparision i have somthing like
3000 cd's
700 sacd's
200 dvda's and high res downloads

I have a Lite Dac 83 and i want to put inside it an I2S input ,I got this email off John kenny about his I2S- Both I2S Hiface solutions won't work, as-is.
The Lite uses + & - for each of the four I2S signals instead of the standard + & ground for each signal i.e. LRCLK+ & LRCLK- instead of LRCLK & GND.
Now I'm looking at
exaU2I So has any one put one into a Lite dac83 or know of, as the wiring seems not the norm

this is the Lite dac 83 I2S pinout is below:

1 : GND
2 : GND
3 : -LRCK
4 : +LRCK
5 : -SDATA
6 : +SDATA
7 : -SCLK
8 : +SCLK
is this compatable with the exaU2I wiring

no, you would have to process the signal in some way. i guess they didnt have in mind anyone using the dac with another input, i do not think you will find another unit that uses this mode as standard

qusp i got an email from exaU2I saying
If you are interested to experiment with it, you can try to connect the exaU2I outputs to the corresponding positive inputs of the DAC. Additionally you have to apply Ĺ of the negative voltage (-2.5V) to the negative inputs. This should work but of course it is not the proper way to do it.

so there is a way maybe

This is exactly what I have been waiting for, I really hope you can make it happen!

The proper way is to use something like SN65ALS176.
