Hi Mark,
Sorry for being silent.
I was pretty busy at work for the last 3 weeks...
I received at the end of last week the ak4137, the xmos and my new 1.07 board.

AK4137 is working ok except for some dsd files. (btw which filter do you use?)

Does the xmos need a psu or is it feed by the usb cable?
(Till now, I always used I2s)

I got my new clock I will try to solder it on a old 1.04 board I have in order to train myself and not ruining the new board.

I'm still waiting for the prototype boards.
Do you have a mouser reference for the copper foil?
It looks that there is hundred of them and I don't know which one to buy.

Hope the mods went well.
I have several pages of the thread to read to catch up.

Hi Terry,
XMOS is powered by USB.

Thing about soldering your new clock to your old 1.04 board, if it works that means you are going to be upgrading the 1.04 board for all the mods then, if that is what you intend. You certainly don't want to solder the new clock to the old board, then unsolder it, the re-solder it to the new board.

You could remove and replace the original clock on the 1.04 board for practice if you want. Maybe the most important thing when unsoldering an old clock to take it gently and try not to scratch up the solder mask on the dac board while doing it since that helps the solder only stick where you want when it comes time to solder a clock back on as the next step. By the way, I did write some more recently about clock replacement soldering.

I don't have a Mouser reference for copper foil. I bought some using ebay and some from amazon.

Regarding AK4137 and playing DSD files, I haven't tried it and that could be a limitation of using it. It certainly seems to help with PCM files. Maybe there is some way to bypass AK4137 when playing native DSD files, haven't looked into it but maybe will have to.

thank you! good to know
I was about to solder it on the old board for testing it.
I read your post about the clock. Very interesting.
When I unsoldered the clock on my old board it was pretty clean.
I will try to do the same on the new.

Problem with dsd files is fixed.
The problem was the rpi and SoX.

Mark,

I'm using Arta with EMU1212M. I wasn't aware of the bit depth restrictions of
the freeware version. I'll have to check that. It surprises me because I was
able to do decent loop through verification of 1212M performance and it
appeared to meet the spec.

This was a while ago, I'll see if I can get time to check this out again.

Hi Terry,
In the sound card setup the unlicensed version has a grayed out setting for wav bit depth, which is locked at 16-bits. I don't know if it only applies to in relation to reading and writing wav files. If only files, then the signal generator and spectrum display depth may be 24-bit.

OK, I don't remember that, will check it out.

In the meantime, have a look at this one:
