According to the linksprite it has i2s output, one of the reasons why I decided to sign up to follow this project closely as I'd love to improve my current audio set up.
Sorry looking at it again, it states pins for i2s is this different from what's needed?
The wandboard looks quite promising too, pricey however it features an Freescale i.MX6 Quad, 2gb of ram, wifi and sata. (which supports multiplexing)

I've checked pcduino3? schematics and it could be way to go... but...
- there are no header for I2S ... only testpoints somewhere
- would it support DSD?
- would it support 384kHz?
The Wandboard does not have masterclock input...
The "features" are not everything... it is far from idea to the realization.

Yes - and clock availability. There is a much wider range of clocks available at <= 50Mhz.
Also clock noise decreases with frequency - there are many other benefits. Digital parts do better when not operating at the extents of their capabilities. 🙂
Hello Russ,
I'm an happy owner of a BIII dac with a 100Mhz clock.
In the past I tried external clock only turning off the PSU of the clock and using the external input, but i don't know why, with poor sonic results.
Now I'd like to remove the 100Mhz oscillator, but at today the only way is to buy from Ian a small pcb adapter.
There is a possibility, are you planning to include in the new system also suitable adapters for this thing?
Sorry for my poor english.
Ciao

You would likely be best off running Async - or simply run a twisted pair (har har) of GND and the mck from the Cronus (I have tested this and it works quite well) - just be sure you run the mck and the gnd twisted to the clock source.,
You can slip a ferrite core on the twisted pair, it does wonders to keep the return current local. Pick one with high impedance at MCLK frequency and smallest hole that will fit your wires.
I normally resist asking, but you did say soon. 🙂
Any rough estimates on prices or when orders will be open?
Boards are ordered we are just awaiting their arrival. 🙂 Brian is still working up prices (no simple task).
Will these boards work with opus DAC board. What all bit rate supported?will this board be able to play bit perfect 44.1K CD audio through Opus? What should be the configuration of boards for Opus DAC?

Hah that is funny - I accidently edited instead of replied. 🙂
- Here is this is what I meant to say:
Yes that would work fine. You would just need to configure the Opus for the sample rate you want to receive.
BTW boards will be arriving in the next day or so. 🙂
Cheers!
Russ
Thanks Russ. Do you have the links to/how to do it, for adjusting sample rates? Does the Opus will need to be reconfigured someway for each materials of different sampling ,bitrates etc?
It's in the WM8741 datasheet. 🙂
OSR switch Controls internal oversampling rate:
0 = low rate (up to 48khz)
Z = medium rate (up to 96khz)
1 = high rate (up to 192Khz)
So - if you have already been playing 44.1-48Khz material you won't need to change anything. 🙂

Or in the parlance of the switches on the board...
- = low rate (up to 48khz)
O = medium rate (up to 96khz)
+ = high rate (up to 192Khz)
sorry for not being clear but I do not have much experience with DAC boards. So with each sample rate material there need to make a hardware change of some kind in DAC board,or will it automatically play anything being thrown at it. Say if I am playing CD rip alternating with a 24bit 192KHz audio track.
