Bella Sound presents the Kalalau Preamplifier

Noise and linearity must be the chief concerns going into a truly high-end preamplifier

design. For these concerns, low noise and high linearity are simultaneously achieved

with a J-FET design. The inherent neutrality of a properly executed J-FET design does

not benefit from the “voice” of any signal path capacitors, hence, none are used.

Instead, high quality film capacitors bypass all four power supplies. The noise and

linearity goals are furthered by the implementation of bulk foil naked resistors

throughout the signal path. Multi-layered power supply filtration is lavished on the

amplifier path to keep the signal in absolute pristine condition. Further care is taken by

placing each of the amplifier channels and the power supply in separate faraday cages.

The architecture is fully balanced from head to tail, including balanced attenuators and a

full complement of XLR and RCA connectors at all 14 I/O’s.

Listening tests have confirmed the achievement of the desired goals: absolute tonal

neutrality, fast and accurate dynamics, and the ability to hear deeply into the recording

to the retrieval of astonishingly minute details.
