Thank you for your purchase of the CF-080LS Hybrid Line Stage Preamplier. This amplier represents the fruits of
over 30 years’ design experience by Masataka Tsuda, during which he has continuously pursued the limits of circuit
simplication and optimization in order to attain the purest music signal possible.
The CF-080LS represents the pinnacle of our thinking in amplier design. It is so advanced that we literally could
not have designed it two years ago!

Before removing the amplier from the box, please be careful of
the following:
1
The Standby/Operation switch located on the rear of the amp is fragile, so care should be taken not
to damage it when lifting the amp from their foam packaging. Similarly, care should be taken not to
damage the rear binding posts.
The pearl anodized coating on the industrial-grade chassis of the amplier is highly susceptible to
ngerprints, so we recommend wearing cloth gloves when handling the amplier. Wipe away
ngerprints using a dry cloth, wiping with the grain of the chassis.
Do not wipe against the grain or use materials which contain silicon, such as the cloths used for
polishing eyeglass lenses.
Verifying that the amplier has not been damaged in shipping:
2
(Before placing the amplier for operation inspection and use in the system, the user may wish to
install the attached feet. Please understand that the feet are for convenience only—in order to
provide clearance for the user’s ngers when the amplier must be lifted—and are not intended to
be “audiophile grade. ” We believe that because isolation devices do inuence the sound to a
greater or lesser extent, they should be chosen according to the user’s taste, which is why we do not
attempt to provide “high-quality” feet that might imply recommendation of a particular tuning
philosophy. Most CF-080LS owners use their own isolation devices between the ampliers and
whatever stands or shelves they are resting upon.)
BEFORE hooking the amplier up to the system via interconnect cables, plug in ONLY the power cord
and then turn POWER switch into the ON position.
Please conrm that white LED on front panel for INPUT 1 is illuminating, showing that the ampliers
are operating properly.
If either the White LED ( INPUT 1) or level indicator is not illuminating, turn o the power to the
amplier, disconnect it from the wall outlet, and notify your dealer.
