A Message from Genesis 
 
The Genesis Integrated 60- att Valve (or vacuum tube) Amplifier is a 
limited-edition product that was created as proof of concept that a well-
designed, well-executed, value-priced amplifier will be able to drive any 
Genesis loudspeaker with ease and authority. 
 
The transparency, detail retrieval, dynamics, and wide frequency extension 
of Genesis loudspeakers place great demands on the quality of 
amplification. Because of our emphasis on absolute fidelity™ above all else, 
the speakers do represent a difficult, but not impossible load for an amplifier 
to drive. The I60 was created as a partner to a pair of Genesis loudspeakers, 
and as a result, it has the quality of amplifiers costing much more. 
 
The I60, together with a pair of Genesis loudspeakers, will give your entire 
music collection a whole new life. In a well set-up system, it is capable of 
transporting the musical performance into your room. The hiss and hum 
normally associated with vacuum tubes are completely absent, while 
retaining the richness and rightness of the best of this genre of amplifiers. 
 
 hile developing a value-priced product, quality has not been scaled down. 
Hand-selected, precisely matched components are used throughout: 
custom-made military-spec paper-in-oil capacitors with aluminum cans are 
selectively used; tantalum-film resistors are used on a hand-built discrete 
resistor potentiometer as a volume control. 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. Each and every unit is first burned-in on the test bench, and then run 
in for over 100 hours before final test and packaging. 
 
Very little feedback is used – just enough to make the amplifier 
unconditionally stable. Not the excessive amount usually employed to make 
amplifiers measure better at the expense of musicality. The result of all this 
obsessive attention to detail is a fabulously musical amplifier capable of 
driving almost any loudspeaker in the world. 
 
Before using this unit, please take the time to carefully review the safety 
instructions and operating information contained in this Owner’s Manual and 
Set-up Guide. Becoming familiar with your new amplifier and the correct 
operating procedures will help assure you of safe usage, reliable operation, 
and maximum musical enjoyment.
