What else to know about the Hera II?

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.

Brief History of Rogue Audio

Rogue Audio amplifier designs combine the finest in tube circuit topology with meticulously engineered circuit layout to achieve superior performance. Unflagging attention to the integrity of the audio signal path and power supplies results in truly superior designs. The most discriminating audiophile will delight in the impeccable fidelity of recordings reproduced through the amplifiers.

The matchless quality of Rogue amplifiers is obvious at first glance. However, Rogue’s quality is not just skin deep. Ultra-high tolerance components, two-ounce copper circuit boards, and silver plated switches are just a few of the many features which separate Rogue products from the competition. The amplifiers have also been designed to be extremely reliable. Electronic components are rated far beyond their intended use, and only the highest quality components are incorporated into the designs. The rugged chassis are treated to resist scratching and corrosion and the machined aluminum faceplates are anodized to protect their appearance.
