In the development.

Device's firmware is easy upgradable from the USB-stick (disk on key)
Are you planning or already set up with a modulatable master clock for the jitter reduction testing?

What is not included in the DIY board kit? It seems to not include the DAC board. Are all the other essential parts included in the PCB kits, including the display?

It is not possible in the current HW, but it is possible to use external 512Fs or 1024Fs clock.

It is simpler to say "what included"

JKGEN Kit - is what you see on a photo.
JKGEN DIY Kit - initially, there are 3 bare PCB (CPU, Output, Front Panel) plus asembled Clock Module.
And only 3 non assembled (used should solder) components:
- CPU with the necessary software inside (bootloader + firmware ),
- Display,
- Encoder.

All other components (including the cables) the user should buy and solder by himself. But I'm flexible to make custom order, and to add some other components (except R and C) with or without additional money (depends which components).
Most comonents that I use are from Mouser and DK.

DAC board includes - "Output".
Full device consicts of 4 molules:
1) CPU Board,
2) Clock Module
3) Output Module (I2S Buffer, DAC and TOSLINK)
4) Front Panel.

Here on a photo you can see all set.
Output Module is old version, with one minor mistake, now ther is a new version.
Front Panel can be or with 3 pushbuttons or with encoder. At photo - with buttons.
(Don't pay attantion to the IR receiver at Front Panel Module and free component places at tha main board - these modules are also used at another product, Jitter Killer).

I got the generator todat and already used it for a few measurements; John Curl's Blowtorch preamplifier part II . I think its even better than it sounds from the description. I have a few quibbles with the UI I'll review with Altor and I'll post some measurements from it in a few days. In combination with a good audio analyzer its a really powerful solution. This is similar Digirator DR2 - Digital Audio Signal Generator but its $1800 and has a lot of features that most will never need.

Ok, that is really encouraging news, and I/we await your detailed appraisal.
Kudos to Alto.

Dan.

I just got another firmware upgrade. Alex has added Jtest to the suite and the UI is proving pretty quick and easy to use now. I'll try to post some measurements from this box later this week.

So far I can say that anyone developing a DAC product should have one. You can do many of the tests with other stuff but not as conveniently and some of the tests are almost impossible to duplicate.
