[ssanmor]

Thanks for the encouraging words, Gertjan, Thijs, etc.

We are indeed receiving very good words from the people that is currently testing the modules. And it is more to come: our offline SMPS is coming!

Best regards,

Sergio,

Thanks for replying to some of our queries, it has become somewhat of a tradition here on DIYaudio it seems; other class-D amplifier module manufacturers have also been posting here. And pardon my critique, but I always call them as I see them.

But as you must've grabbed from my posts I'm not a fool for good looking PCB's or a spec. sheet without some clear plots and graphs. I'd be interested to see the THD vs. power and THD vs. bandwidth plots of your amplifier, only then I can make a somewhat educated guess on how they compare to other modules.

I'd also be interested to learn why you adopted a synchronous topology and if you want to disclose this some details about the amplifier, it's modulating scheme, etc.

Looking forward to your reply.

Best regards,

Sander Sassen
