Dear friend,
I am using the kraft-300 with symphonic line rg3 mk4-turbo psu SS preamp.
This is the most amazing set-up I have ever listened to.
The speaker is magico's mini mk1 speaker that alows this set-up to show it's exceptional quality.
The kraft does not sound like a very good amplifier.
It is really a creation of great engineering and art(by the means of great sonic tests and decisions done by symphonic line crew).
My feeling is that the kraft-300 has the rare ability to recreate the exact sonic pulse fed to it (and this is what most amplifiers lack, even the most expensive ones !!)
AMAZING tonality, colors, vividness, speed, bass accuracy and detail ,slam, sounstage etc.
Not just perfect, but mainly an extremely enjoying amplifier.
