PREFACE
INTRODUCTION
This manual covers the use of the Metis, using references to the hand held remote which has
a separate owner’s manual.
Thank you for purchasing the Metis Line Preamplifier. It has been engineered to deliver the
highest attainable sound quality. This is its sole purpose. Only the highest grade electronic
components are used in the Metis, including: non-inductive Roederstein metal film resistors
in the signal path; polystyrene, polypropylene, and electrolytic power supply, bypass, and
signal capacitors; low noise matched vacuum tubes; glass epoxy circuit boards; 16 gauge
aluminum chassis; custom wound low flux power transformers. The Metis has an internal
floating power supply which is isolated from the chassis when placed on a stand. The only
contact with the rest of the unit is the transformer wires connected the power supply circuit
board.
PLACEMENT
The Metis should be located away from possible sources of hum such as power cords, power
transformers and the like. It should not be located near any other heat source such as a
power amplifier or power supply. It must be kept well ventilated any time it is on. If it is
positioned within an enclosed space then fans may be warranted. All air vents must remain
unobstructed. It must be installed on a flat surface that is in contact with all 4 round Nimbus
Couplers.
BURN IN TIME
This unit has a break in period of about 400 hours during which continuous improvement in
sound quality will be observed.

IMPORTANT
Save all packaging in a dry place away from fire hazards. Your Metis is a precision electronic
instrument and should be properly packaged any time shipment is made. In the unlikely
event that you have to return your Metis to the factory for service, or if you send it to us for
updating, the original packaging will best protect the unit from shipping damage.
In order to achieve the fullest flexibility and enjoyment from your Metis, we highly recommend
that you read this and the separate Remote manual in full before connecting the unit to your
audio system.
Note: It is imperative that the Metis be operated in a well ventilated environment and the
immediate external temperature be maintained as specified. External cooling fans
may be required in some cases. Do not stack any equipment directly above or
below the Metis to protect it from overheating, as well as the continued functionality
of any equipment near and around it.
WARNING
United States law prohibits disposition of these commodities to Libya, Laos, North Korea,
Cambodia, Syria or Cuba unless otherwise authorized by the United States.
AFTER MARKET and THIRD PARTY MODIFICATIONS
Please note that any aftermarket and/or third party modifications will void the warranty.
There are Harmonic Resolution Nimbus Couplers in the corners of the main chassis, and 2
Aesthetix feet on the power supply. The height difference between them is critical and must
be maintained at all times for the floating power supply feature to function as designed.
Please do not change the feet.

Initial Setup
With the AC cord disconnected, remove the Metis top cover by first removing the two Philips
screws on the rear panel closest to the top, then lift each rear corner one at a time – going back
and forth between left and right. It is fastened with a stiff double-sided interlocking material.
Install 4 tubes into the Metis. See Metis Tube Guide. Afterwards, replace the top cover and secure it using the
same 2 Philips screws.
Connect all sources to the Metis rear panel inputs,
If used, connect a trigger cable to the device that the Metis standby will either control, or be controlled by.
Connect the Metis outputs to the Power amplifier inputs.
Ensure that the power amplifiers are off or muted prior to making connections to, and tuning on the Metis rear
panel power switch.
Turn on the rear panel power switch.
Note: The hand held remote is shipped in “Transport” mode (off). It must first be set to Active. Please refer to the
remote owner’s manual. See the Metis Remote Owner’s Manual.
If it’s not already, install one battery in the hand held remote control. Note that a remote extender is included to
extend the remote range, if necessary.
CAUTION! To avoid loud pops and possible speaker damage, turn on all other system components
before taking the Mimas out of standby.
Standby
The Metis will boot up into Standby. Pressing the blue Standby button will initiate the startup process, in which
the blue LED will blink for a few minutes before displaying the Main Menu.
