Yes, I tried last night and it's working, but only from the usb input.
Form the usb card I have no sound.
I just tried again and the same. Of course everything was turned on before I start the PC.

I should try maybe a diferent slot for the usb card?!

To repeat myself........thanks again! :)

its 48mhz 3.3v level to xmos and 24mhz from ff at 3.3 v levels to usb hub
i had assumed if i put in 24mhz in to xmos without programing it would either not work or play at half speed
ill try a 24mhz before i fit it to the soekris just to see what happens

Sorry, yes, I meant 48MHz to XMOS - I don't think 24MHz will work without programming the XMOS

ive it running on a pcm5102a for testin and sounds pretty damn decent although not the same natural sound as the r2r
a good tight detailed snappy sound, timings probably improved over the other front ends ive heard on this dac

no neg effects so far and must be playing a few days now non-stop

Great, sounds very promising

seems a little more crisp and assertive at 3.3v levels on soekris
will give it more time

Cannot think of a better place to put this but looking through this thread on making a super clock I saw this post.

If I cared I should post the link at AA but ...

Seems like the things are quiet.

Saw this:

Wonder what the difference is between this and the REGEN?

Uses bus power but I guess that would be easy enough to change, but the price is high.

Hi Rick, got one purely for its isolation claims and it seems to work well so far, I had the Giso Isolator previously from my JPlay dual PC days for Ethernet Isolation between PC's and it also worked well so this prompted me to purchase.
Some pics below:

is that two usb2412 chips on each end?
doubt theres any need for 5v on this
maybe new 3.3v supply?

Thanks for the pics, Pearse - very interesting
This device is regenerating the USB signal so it effectively does the same a the Regen but I see some potential weaknesses in that part of it's functionality

I can see that the device uses Xilinix FPGA to do the heavy lifting although the two chips (are they from FTDI?) between the FPGA & USB ports I would guess are responsible for translation to/from USB signal protocol. I see the isolators between the two sides of the board (giving 8 channels in each direction) & also the coilcraft transformer spanning the two sides of the board which I presume is responsible for the isolation of ground & +5V but I can't see how this can really provide clean PS on the other side - it is 5V on primary & 3.3V on secondary side - also the spec for the Intona says "Powered by USB host device; internal DC/DC converter for isolated side" - this whole PS area, I expect is a possible weak link although it appears to be helping SQ by isolating the other pathway for noise transference, the USB D+ & D- data lines

If the "clean" side was powered by a good PS supply, I reckon there would be some improvements. What I also don't see is a clock on the board but there is one black block that might be it ( I can't read the ID) - a decent clock with good PS might also be an improvement, I reckon.

But all very interesting - thanks for posting, Pearse

Hi John,

I have the Intona before the Regen so just for the Isolation but as you say if it could do a good job of regenerating USB then maybe no need for Regen.

Below is probably the chip you are referring to and the other 2 pictures maybe help you are looking for clock, i could not see anything!!!
