Die Kunst der kleinen Schritte: AVM SD 8.3 und MA 8.3 im Test
„AVM gibt ein Lehrstück darüber, wie man vertraut bleibt, ohne in der Zeit stehenzubleiben. Die AVM-Entwicklern ist es bei einem völlig offenen Umgang mit der technischen Herangehensweise gelungen, nicht vor lauter Bäumen den Wald aus dem Blick zu verlieren. Das Vor-/Endstufen-Gespann gibt sich völlig neutral und im besten Sinne charakterlos und wuchert dabei mit so einigen Pfunden, ohne jemals mit ihnen zu prahlen. Bauteile und Schaltungen oder Leistungs- und Dynamikreserven stehen hier stets im Dienst einer jederzeit absolut souveränen, authentischen Musikwiedergabe. Die Kombo SD 8.3/MA 8.3 ist für AVM ein weiterer Schritt nach vorn – vor allem aber sind es wieder einmal echte AVMs.“
