Hera
II Preamplifier
After more than three years of research and development, Rogue Audio
proudly introduces the Hera II reference preamplifier. The Hera
II ’s innovative and proprietary circuitry utilizes eight
of the Russian military’s 6H30P tubes in a balanced design
that stretches the bounds of modern preamplifier technology. And
that technology translates into amazing detail, smoothness and refinement
which has effectively redefined the level of performance that can
be expected from a reference caliber preamplifier.
The
Hera II is feature rich yet sacrifices nothing to sonic integrity.
Many of today’s high end designers make extensive use of microprocessors
and the digital domain to support features that ultimately detract
from the audio
performance -- At Rogue Audio we eschew such technology. Every
aspect of the Hera II's design is aimed at maintaining near perfect
signal integrity. To that end, we have developed cutting edge circuitry
that is realized using only the very finest components available
today. A motorized TKD potentiometer provides ultra smooth volume
control and all functional switching is done via heavy duty silver
switches rather than being routed through a silicon chip. Capacitors,
resistors and all other critical parts are of the highest quality
as well. The two box chassis itself is a fully machined work of
industrial art that provides the electrical isolation necessary
for the incredibly low noise floor of the Hera. The ultra-sophisticated
design also includes a phase invert button, balance bypass, processor
loop, unity gain bypass and a host of other features. Our driving
design goal for the Hera II was to set a new benchmark in vacuum
tube preamplifier technology - we believe we have succeeded.
