Sutherland MCX Owner's Manual - The Appropriate Answer

The Appropriate Answer
First, the SUT needed to sit directly on the
preamp circuit board. This decision brought
with it many advantages. The connections
between the SUT secondary and preamp
circuits were now as direct as physically pos-
sible. The distance was minimal. The inter-
connecting cable was eliminated. Two sets of
audio connectors were eliminated. The signal
path was simplified and made more direct.
Furthermore, the cost of cables, connectors,
and transformer case was eliminated.
But which transformer should be used?
Although some preamp manufactures design
and build their own SUT, that was never a
serious consideration for this project. I would
much prefer to incorporate the expertise of
an established expert in the field. Lundahl
has a well deserved reputation for good, solid
engineering that delivers both quality and
musicality.
Using a transformer in front of the first gain
stage offered a chance for some circuit sim-
plification. Then the following stage was
revamped for the best overall musicality.
