The D-110 is
a linear 2-channel power amplifier of extremely high quality construction
designed for the reproduction of speech and music. It represents "second
Generation" advancement of Audio Research's analog module technology.
With the
D-350 and D-100A technology to draw from, the D-110 was conceived to embody
those parts of each design that could be brought together to provide an
amplifier having the very highest possible performance level within its power
capability.
Assuming a
basically linear and stable amplifier design with adequate "slewing
rate" to allow possible audio waveforms to be reproduced with low
distortion, there are still two most important factors that must be dealt with
if it is to be capable of driving loudspeaker loads "fast and clean".
One is the "stiffness" or "muscle" of the output-driver
stage; the other, a stable high capacity power
supply, capable of providing the instentaneous current demands of the
circuit. By utilizing the D-350 power supply, with its 300 joule energy
storage, and the D-100A output stage rebiased to a much higher "idle"
current (the 3 built-in, superquiet fans keep the ambient temperature to a very
reasonable level), an amplifier has been created that provides a new level of
music reproduction. To obtain the performance this amplifier is capable of, it
is recommended that only commensurate quality preamplifier-control units (such
as the SP-3B, SP-5, SP-6) be used with it. Also, only high quality turntables
with stable arms and cartridges should be used.
