The Duet 350 Amplifier
Real music fills a room. Even the softest instruments are more present in life than most music systems can reproduce from recordings. Part of the problem has been the limitations in power amplifiers.
The Duet 350 Power Amplifier is a stereo power amplifier that has achieved affordable excellence in sonic quality, power capability and reliability.
In its normal stereo mode it has more than enough power to drive most speakers to their limits with the kind of open, clear, effortless sound which are the hallmark of Cello. When used in a bridged configuration, the Duet 350 becomes a mono block power station capable of high speed and powerful dynamics under any condition.
The Duet 350 Amplifier has been specifically designed by Cello engineers to be compatible with a wide variety of available equipment.
