MC Transformer SUT
The Story
At the European Triode Festival 2013 in Berlin we made a small MC-Transformer
listening shoot out. To my surprise, it was easy to hear a difference from
one to the other SUT. Later I thought it should be possible to see also differences
when measuring them. But it took me some time, to get professional
measuring equipment, the know-how of friends and a lot of time to get results.
So I hope I can help the DIY’s to get the desired SUT for listening.

The Story
My ears and my brain are not so excellent to remember and compare
the quality of the same Music track played on two different audio equipment
after each other, as made often by shoot out competitions.
So I decide to build audio switch equipment for professional A/B Tests.
