Hello sir, did you achieve success with your Board? I am looking around for a nice (eval) board!

I am also still interested in the SSM3582, but maybe sgpu had too much on the plate. maybe too many design consideration requests from me, I do not know. The layout near the end of the development was very interesting, and it might even be fun to try it out as a more powerful pre-amp stage.

I have a dev board kicking around now. Used to power 10 x Audio Nirvana Super12s for a church organ project. If you want one I can arrange a quote, maybe a group buy?

sgpu

Are you thinking of a group buy of the project you've made here or?
Still interested!

:-)

I'll produce some technical reports using my UPL and upload some photos. There have been some minor changes. Currently supports 10ch at 44.1/48Khz 16/20bits over USB2. Just seen as 10 channels to ASIO.

... What exactly is the improvement over SSM3582?
I would still prefer the '3582. The noise figures are almost identical, with slight advantage to '3582, power figures are also nearly identical with slight advantage to '3525.

Oh yes there is no performance progress - it was rave emotion too see something new. Performance is unexpectedly high for such tiny modules. The progress is in other places. First, this is ability to work with 17VDC which allows using 4S Li-Ion battery packs. Higher voltage of 4S packs and a bit higher output voltage swing of these new modules will result in higher power-density of mobile devices. There is also output current, output voltage and battery voltage monitoring added as well. All in all, some improvements...

I am courious when someone will DIY-build this into working amplififer. I could even pay someone for doing this for me.

Another argument in favor of the SSS3525 is the price. And number of pins, it needs so few solder points that even if it's uBGA it should be fairly easy to "bake on" in the oven.

Edit:
Is the SSM3525 only in mono?! If it is, it's NOT cheaper, and there is more work involved.
