It looks like battleship or a hypersonic plane 🙂
The metal standoffs - a lot of magnetic iron there - I would use nylon instead; no magnetics and lower Q singing resonances... acoustical feedback still remains also in DACs...

Some influence of times, export version may look different 🤣
Stand-offs and risers not part of standard supply. The ones shown are nickel plated brass, so non- magnetic or other concerns? Just showing possibilities for any add-on modules later - perhaps for a tail kit🙂 End users can decide on material type for the fixtures. Can be suspended fixtures to reduce acoustic feedback if needed. Critical components like caps are film type so not much affected by vibrations. Clocks can be externally piped in.

Yes, I did. going through many inquiries recently, so bear with me for a while and I will get back to you soon🙂
Firmware development for the controller completed and loaded onto Controller. Marathon effort to effectively control two chips of this AKM dac, including dual mono mode. Early tests indicate successful ‘lock’ and some control functions working as intended - no audio feed yet. Next step, to confirm all registers set properly and then live tests🙂
Thanks for your support and patience. yes taken some 2yrs of work on a fairly complex design but rest assured very easy to setup for the standard configuration. Planning for production now so won’t be long🙂
Designing is not an easy thing. Good Job!
How it sounds? I'm only listening in mono mode. I'm curious how single chip in stereo sounds.
Initial impressions: Pretty amazing sound actually in stereo mode, very clear and detailed with all the dynamics. No tweaks on power supply or clocks yet in the standard build and bettered all my previous DACs.
Testing… @DSD256
DAC needs +/-15V master supply (9-15V). On-board regs distribute to all different sections. Simplifies power supply arrangement. If preferred, on-board ones can be bypassed for choice of external supplies for just about every section e.g. batteries, ultra caps etc..

There is also a DSD Volume bypass mode that is more direct and possibly even higher performance🙂
Its a pity that xmos still no way to go higher than dsd128 * 8ch. MCHstreamer seems the only one to do it, dont know pink faun i2s bridge capability though
