Speaker Level Connection

Use the best speaker cables you can. The length and
type of speaker cable used in your system will have an
audible effect. Under no circumstance should a wire of
gauge higher (thinner) than #16 be used. In general, the
longer the length used, the greater the necessity of a lower
gauge, and the lower the gauge, the better the sound,
with diminishing returns setting in around #8 to #12.
A variety of cables are available whose manufacturers
claim better performance than standard heavy gauge wire.
We have verified this in many cases, and the improvements
available are often more noticeable than the differences
between wires of different gauge. The effects of cables
may be masked if equipment is not of the highest quality.
Connections are done at the signal input section on the
rear electronics panel of the Source. Use spade connec-
tors for optimum contact and ease of installation. Hand
tighten the binding posts, but do not overtighten—do not
use a tool to tighten the binding posts.
Be consistent when connecting the speaker cables to the
signal input terminals. Take care to assign the same color
cable lead to the (+) terminal on both the left and right
channel speakers. If bass is nonexistent and you cannot
discern a tight, coherent image, you may need to reverse
the (+) and (–) leads on one speaker to bring the system
into proper polarity.
WARNING! Turn your amplifier off
before making or breaking any signal con-
nections!

Break-In

When you first begin to play your Source speakers, they
will sound a bit bass shy. This is due to the high quality,
long-life components used in our woofer. Our custom
made, butyl surround woofer requires approximately
72 hours of break-in at 90 dB (moderate listening levels)
before any critical listening. The break-in requirements of
the crossover components (and, to a lesser degree, the
stator) are equivalent.
