A little background info…

Designed and engineered without compromise, the Ninety-Nine boasts ruler flat response, tremendous bandwidth, huge dynamic range, and low levels of distortion. However, extraordinary test-bench specifications tell only part of the story. While tube preamplifiers are widely regarded as providing the most natural and appealing sound, the Ninety-Nine preamplifier must be auditioned in person to be fully appreciated. From a technical standpoint, the Rogue Ninety-Nine utilizes four 6SN7 tubes configured in a mu-follower circuit topology. An analog remote volume control enhances the listening experience without compromising sonic integrity, and a logical turn on procedure protects downstream components while prolonging tube life and performance. The massive power supply includes a toroidal transformer in a separate chassis, high-speed HEXFRED diodes, seven separate regulators and a toroidal high voltage transformer. An uncompromising “leading edge” design housed in an elegant and refined package.
