Najwyszy model wzmacniacza \"Professional Series\" . Seria profesional to trzy modele AU-9900 AU-11000 AU-20000. Konstrukcja i wykonanie perfekcyjne.Dziękowo stara szkoła dzwięku .
Pierwszy raz jak go podłonczyłem - oniemiałem - czysty klarowny dzwięk z detalami jakie do tej pory nie były szłyszalne na innych wzmacniaczach .Dzwięk od pierwszych taktów poza kolumnami - kolumny poprostu znikły.Dne techniczne--Power Output:
