Bare Boards and Kits
Yes, these are available for those wish to iron out things themselves. The site is new and will put this options soon. In the meantime enquire about custom options.

USB-I2S Module
Yes, the MCU module can do this.
John (Jkenny) is handling the USB-I2S module and will update with more details.

Thanks Acko,
As I PMed to Zaireeka:
The USB module that will be offered with the AckoDac is based on the modified HiFace 24/192 asynchronous USB transport that I've offered elsewhere as a stand-alone USB transport. It will plug into the input of the AckoDac feeding it I2S signals (not the inferior SPDIF). This means high quality, high res USB audio is available directly with the AckoDac
The options, pricing & testing of this module has yet to be finalised so please bear with us a bit longer

couple questions:
-can one AKR3312 supply the entirety of the dac without problem for those who dont want to shell out 600$ in one shot like me?
-is only one prduction run going to be made and that s it, so that you better buy what you want right now?
- do you have some kind of test results for the regulators and current/voltage capabilities or things like that? maybe one could be interested in using these in other projects.

Trying to answer some of your questions: The current requirements for the combined supplies into the DAC:
Combined 1.2V supplies 130mA
Combined 3.3V supplies 90mA
I'm not sure the max current output of the KR3312 but will check.
Remember though that the Sabre DAC is VERY sensitive to power supply quality & to get the best from it requires some separation of supplies & the best quality that can be provided.
No, there are on-going production runs
See above answer & more detail to follow
ok thanks i ll be waiting patiently then 
i m pretty sure the dac offers terrific bang/buck, but for someone who doesn t want to spend for all the regulators all at the time, it would be nice if the dac could work off a single regulator, so that one could add more regs later on if he feels the need for it, not to mention the competion TPA would then have
keep the good work guys

its just not really possible I would think, there are no regulators on the PCB, so they should each have their own regulator. as I see it the TP guys have already got a fight on their hands. especially with the tweakers set, the deluxe version uC is well ahead of anything that is currently available from TP. being that this is like buying the buff (well actually a more built for speed version of one) and not using the onboard regs and instead buying high end regs for each of the inputs. I can tell you that would cost a lot more than 600. i'll wait for acko to answer, but that would be like only having 1 or 2 onboard chip regs and trying to run the sabre from that, this is far from even what the datasheet would require, let alone a design that is trying to take it further.

This DAC is fully modular. Yes, you can of course combine and run all the relevant supplies from a single source and can use any low noise regulators for that matter. The AKD3312 have been specifically designed for this DAC and has maximum output is 50mA only per output. The AVCC pins of the DAC draw about 32mA each @80MHz clock, so combining them exceeds the current capacity of the ADDR3312. If you wish you could use Paul Hynes Regs (200mA drive) or similar instead. So those who wish to use other types or roll out their own regulators, the current consumption on each lines @80MHz clock are:
AVCCR (3.3V) = 32mA
ACCCL (3.3V) = 32mA
AVDDL (1.2V)= 8mA
AVDDR (1.2V)= 8mA
VOSC (3.3V)= 10mA
DVDD (1.2V) = 105mA
DVCC_T (3.3V) = 5mA
DVCC_B (3.3V)= 5mA
There will be continuous production as long as there is supply/demand for it.
The AKD3312 have been specifically designed for this DAC and optimized as such. Other similar projects could use it (within the operating limits) but sorry no support for these.
Yes, it is ok to source from a single KR312, plenty of drive left. Just take care to keep the wirng short.
