I work on W7 Ult. 64 bits.
Player is XXHighEnd , latest version.
I managed getting it work up to 24/192! In Wasapi however.
Trying in KS does not work higher than 16/44. Which is a pity because I miss a lot of settings in the program to let it sound optimal.
Maybe I2S-coax works in a different way. I will need some more time to work that out. I'll let you know,
All the best,
Ed
Maybe somebody out there expierenced the same as I do??
Asio or Wasapi no problems.
On KS only 16/44.

Hi,
I should add to the above story that I CAN choose up to 192Khz, though it is not possible to choose higher bitrates than 16.(In KS)

Hi,
Wave I0 + Alix 3d2 + voyage mpd + 24/192 files
Is it a good idea?? Work well?

HI Lorien

I received the waveIO today. Thanks for the excellent work. Both my Mac and Win 7 recognized it without problem.

I connect it to Ian's FIFO via I2S, I can see the "lock" LED on FIFO but the BIII does't lock. Test the signal path by Ian SPDIF and everything work fine. Any advice to diagnose the problem?

Thanks anyhow!

Anybody can give us the number of sample/buffer/latency of the last XMOS hardware with the best ASIO drivers available..

I want to buy this - http://www.minidsp.com/images/docume...SBstreamer.pdf

******* tired of companies not talking about asio latency of their drivers like if nobody is interested...

Also what about jitter of the xmos chip... (since it need to be the master clock)

I also need to know the driver company.. like centrace or others..

XMOS interfaces do not need a driver on OSX or linux platforms, as the XMOS is USB class 2 audio compliant. Third part drivers are only required on Windows OS, since Microsoft does not feel the need to compy with the USB class 2 audio standard.

Not sure what you mean about the jitter of the XMOS chip? Jitter at the output of the Wave IO as far as your DAC is concerned, will be the jitter of the masterclock oscillator as the MC is sent directly out over I2S. Of course there will be slight additional jitter if you use the isolated outputs (~20 pS or thereabouts), but the straight outputs should be just the inherent jitter of the MC, as the XMOS chip does not alter the clock. I would be more concerned about keeping the I2S lines to the DAC as short as possible, and terminated as well as possible. I suspect the mini bnc cables and jacks are good in this regard.
