I60 Owner’s Manual Ver 1.2
attenuator is employed as a volume control; low-noise gold plated military-
spec ceramic tube sockets are used throughout.
Very little feedback is used – just enough to make the amplifier
unconditionally stable. Not the excessive amount that is sometimes
employed to make amplifiers measure better at the expense of musicality.
During construction, all
components are hand-
selected and precisely
matched. The output
transformers and power
transformer are laboriously
hand wound to precise
specifications tailored to the
circuit and tubes used.
Point-to-point wiring using
solid-core silver wire is used
in the entire signal path. This
reduces the resistance,
capacitance and inductance
normally associated with
ordinary printed circuit
boards.
The only PCBs you see in the “guts” above are the boards associated with
biasing of the power tubes, and the soft-start electronics.
The output transformers are custom designed and hand-wound with a core
of grain-oriented silicon steel specifically for the output tubes used. Two
output taps are provided on the secondary – 4ohm and 8ohm – with the 4
Ohm tap specifically tuned using Genesis loudspeakers.
Each amplifier is extensively inspected and tested at every stage of
manufacturing. It is also allowed to burn-in before the valves are biased and
calibrated, and then run-in for 100 hours before finally being electronically
tested prior to packing for shipment. Hence, it should come to you ready to
use straight out of the box.

Matching the impedance between your speakers and the I60 is one of the
most important sonic factors in your enjoyment of this amplifier. Please
