The Chapter Two+ is a new “state of the art” audiophile two channel power amplifier
incorporating a unique combination of design features coupled with scrupulous attention
to technical detail.
 
Chapter Two+ Power Supply. The Chapter Two+ uses an advanced, double regulated, 
switched mode power supply to achieve very high performance coupled with relatively low
weight and compact dimensions. The power supply incorporates active universal power
factor correction (PFC), which gives levels of regulation and dynamic performance
several orders of magnitude better than the best linear power supplies. Energy is
supplied at a rate 1400x faster than any linear supply can provide giving this
amplifier an effortless quality even when faced with the most demanding of loudspeaker
loads. The Chapter Two+ allows universal operation from any mains voltage between 85
and 265Vac at 50-60Hz. Thus total audio performance is guaranteed anywhere in the world.
In addition, the amplifier will ride severe mains “brown-outs” without audible effect
meaning the quality of the mains supply will not upset your listening enjoyment. Unique
circuitry coupled with expert RF filter design and layout allows the Chapter Two+ to
meet the most stringent tests for radio frequency emissions including the EN broadcast
specification. 
 
Chapter…great expectations in “state of the art” audio.
