Rogue Audio Magnum Ninety-Nine preamplifier
Rogue Audio's Magnum Ninety-Nine tubed preamplifier is derived from the original Rogue Sixty-Six that I <A HREF="http://www.stereophile.com//amplificationreviews/289/">reviewed in October 2000</A>. The Sixty-Six was designed to offer consumers a taste of high-end performance in a vacuum-tube line stage. By constrast, the Magnum Ninety-Nine's pedigree is pure audiophile, with a more sophisticated mu-follower circuit topology aimed at the purest expression of performance.
