Los mejores clase D que he escuchado son:
Nuforce del Amiratos y el Virtue de Al. No puedo pronunciarme por las diferencias , ya que los esuché con cajas distintas ,
Nuforce+ Dynaudio y Virtue+JBL 4350 ,pero bien ricos ambos amps.

Hay alguna nueva informacion sobre esta comparación?
Como anda W4S contra Nuforce y Virtue?
