Power Amplifier 9011

The 9011 features everything that its smaller sibling, the 9008 A, has to offer – and then some. It begins with the delivery of more long-term power output and short-term current distribution, a feat achieved by way of three groups of eight output transistors each, eight electrolytic and charging capacitors, plus a third 400VA toroidal transformer to further increase charging speed and facilitate speaker load matching.

he MBL 9011 delivers the full spectrum of front-row, concert-like sound reproduction from your cherished music.
