Why? This would seem to add unnecessary expense to the product.
Perhaps I am biased, since I made a feature request that the new hardware be based on a single PCB without a daughter board. Single-board reduces the number of connections, which are a point of failure. Single-board also alleviates the need to buy a retail product as a manufacturing component of another retail product - it's much cheaper to just buy the individual electronics and place them directly on the main board compared to buying a sub-assembly that is separately manufactured.
I also have my doubts that the iCron board can be programmed with custom firmware as easily as a proprietary design from exaDevices.
IMO, products of exaDevices have marked breakthroughs in their performances; 386kHz/32bit 8 channels, DSD512 play, etc. That's the reason why people are interested in them. Isolation of High speed USB in an audio application domain is not achieved yet. This is a challenging thing to do.
From the point of view of one of audiophiles who always pursue the best sound quality, I hate to have my audio master clock oscillators share a ground ( a source of electron flow ) with a noise contaminated PC.
However, from the point of view of audio device selling business, your thought is reasonable, of course.

I am playing (have been doing that for a good period of time already) with isolation of USB (480MB/s) with both exaU2I and other USB implementations.
This is the greatest upgrade you can implement with PC / Mac USB based systems.
I have isolated USB connections with copper wire, silver wire and pure gold wire.
Isolated USB with pure gold wire insulated with pure silk are by far the best sounding.
These observations are based on my setup where the internal cables in the DAC are pure gold with air as isolation, the interconnects to the power amplifier are pure gold with pure silk isolation, the PCB´s are gold plated in the whole system, the speaker cables are a combination of pure silver and pure gold - isolated with pure silk.
Power amplifiers are pure JFET, speakers are pure AMT fullrange.
And my Mac OSX player system have no fans, SSD HDDs, custom PSU with JFET regulation and more capacitance
than most power amplifiers, and runs from a 12 volt battery source.
Hi RayCtech,
So I guess you're kinda "purist" person...
As much as I respect your approach and would love a setup like yours, most of us cannot afford the type of cables you're using... Pure gold with silk, how much per foot?
Ciao!

I hope exa065 will tolerate this OT postings
The largest contribution to cost is the odd 40 hours of work pr. meter of cable (silk insulations) as they are 100% very perfectly made by hand...

Hi guys,
As you know I wear two hats - I am a DIYer by destiny and I produce products for profit. It is fine to post here for the benefit of both causes. Just manage your conflicts of interest as I manage mine.
I enjoy tremendously XXL volume controls with ball bearings and gold and silk wires. I don't believe in supernatural cables, but handmade gold and silk cable - this is a work of art, it is like a 13th century katana with a silk handle...it is a weapon for sound supremacy.
I wonder, how come it is an honourable occupation to search for the illusive sound in all areas of R&D, except proprietary sound drivers. Double standards....
Hi Javin5,
We will use top quality clocks and we will make the clocks and the clock power sources replaceable. Synchronous operation is also on the task list.
-Best,

Oh, that's great!
You must have completed the work quoted below that had required exa065's help.
However, it's pity that no one other than you can reproduce the way you have established in-house.

USB isolation works..
SATA / eSATA and I2S isolation works..
The method I now use (there have been some technological improvements) do not add jitter or noise, but actually reduces lower frequency phase noise etc..
The next I now will work on are isolation of clocks (master clocks) as I may be able to reduce the low frequency noise / phase noise by more than 60dB at 10kHz and more than 100dB at 10Hz if the "isolation" performs as expected.
I will assemble some few USB, I2S and master clock isolation modules and let some hardcore DIYers evaluate the performance.
As isolation can easily be switched on / off I can also implement a remote control to do this switching in realtime...
There will be no more dedicated threads regarding any of my ideas
Exa065 - this will be my last OT posting in your threads...
As this may be my last posting on diyAudio.com except in those threads I have started myself I will use the opportunity to say goodbye to all the great personalities I have encountered here
Why do you think you find that gold sounds "far better" better than copper or silver, when it is actually a worse conductor than both?
NicMac, disclosing a private message is a very dishonorable thing. You are not welcome here anymore.
May I ask about a conventional channel assignment rule on DSD playback?
ExaU2I supports a DSD play. The connection diagram for DSD signal output is shown on this ExaDevices web page.
Native dsd playback from WinXP PC using the exaU2I
The notion, "DSD data 1" and "DSD data 2", is used here.
When a stereo play is applied, which channel is to be assigned to "Left" according to a conventional rule?
