Rogue Audio

Rogue has recently introduced a Magnum version of their Ares phono preamplifier at $2795 which improves on the already-excellent Ares model. They have also released their latest model preamplifier built on the RPX platform, the RP-7 at $4995.

The Ares Magnum is an ultra-high-performance, low-noise tube phono preamplifier for low-, medium-, and high-output mc and mm cartridges. As good as the Ares is, Rogue regularly received requests for an even better version. The Magnum version adds additional gain for very low output cartridges, improves inner detail , and improves accuracy. The Magnum upgrade includes:

• Cinemag blue label step up transformers
• PRP resistors in critical spots of the signal path
• Mundorf Supreme inter-stage coupling caps
• Cardas internal wiring
• Upgraded Cardas RCA jacks
• Compatible with almost all low, medium, and high-output moving coil (mc) and Moving magnet (mm) cartridges
• Ultra-heavy-duty gold RCA input connectors
• Precision components throughout

The RP-7 is Rogue's first balanced preamplifier designed on the RP-X hardware/software platform, and every aspect of the RP-7 design is aimed at maintaining near perfect signal integrity. Beyond the computer-optimized circuit topology, all of the capacitors, resistors and other critical parts are of ultra-high quality assuring the highest sonic integrity. The sophisticated electrical design is based on pure class-A tube amplification with mosfet output buffering to provide huge drive capability along with a super low output impedance.

In addition to the excellent sound, the feature-rich RP-7 provides all of the functions demanded of a luxury hi-end preamp. Included are a home theater bypass, a processor loop, a mono button, a defeatable display, slow start circuitry, and a host of other features. A full function remote provides additional convenience. Two pairs of XLR inputs and three pairs of RCA line level inputs allow for numerous source components while two pairs of XLR outputs along with two pairs of RCA variable outputs facilitate a wide range of output connectivity. Also included is a high-power, tube-based headphone amplifier capable of driving even the most difficult headphones.

The attractive design includes an easy to read OLED display that further enhances the preamp's sleek and elegant appearance. The display provides all relevant information in large, easy-to-read azure-tinted characters. The ultra-high-quality tactile buttons and knobs further add to the exclusive feel of the RP-7. A summary of its other features includes:

• Four 12AU7 tube mu-follower design
• Ten function remote control
• Home Theater bypass/Unity gain inputs
• Machined aluminum faceplate and knobs
• Tube based high power headphone amp
• Massive power supply
