Default Class D Delta-Sigma Amplifier

For those who are interested, here is my latest Class D Delta-Sigma Amplifier.
There is a German Audio magazine with design projects which is published monthly - can someone tell me what the name of the magazine is and/or direct me to their web site?
Thank you.

Hello Tekko,
It is self-oscillating at approx. 400kHz.
Unfortunately I am not showing any circuits now.
Greetings.

Hello Nilsomat,
Thank you for your reply. No, it is not Elektor, something more like the American magazine AudioXpress. I believe it is one of the best magazines with practical audio projects. They also have a companion German magazine on practical loudspeaker projects.
Sincerely,
Stephen.

There are two big magazines for diy loudspeakeakers : Klang und Ton (see above) and
http://www.hobbyhifi.de/

I checked the homepages briefly, but didn't really find something...

Good Luck
Nils
