Rogue Audio RP-9 v2 Preamplifier

The Rogue Audio RP-9 v2 stands as the flagship preamplifier in Rogue’s acclaimed lineup, representing the ultimate fusion of tube musicality and technical mastery. This version 2 iteration is built upon a streamlined, proprietary circuit designed specifically around the superior linearity and dynamics of the legendary Russian military-grade 6H30P tubes. The RP-9 v2 is engineered with the overarching goal of maintaining near-perfect signal integrity, achieving an ultra-wide bandwidth, and possessing a vanishingly low noise floor. The result is a component that effortlessly delivers expansive soundstaging, liquid smoothness, and unparalleled dynamic refinement, effectively setting a new benchmark for reference-caliber preamplification.

Key Features:

• Flagship 6H30P Tube Design: Utilizes four military-grade 6H30P "SuperTube" valves in a fully balanced mu-follower configuration for superior linearity and dynamic headroom.
  
• Ultra-Wide Bandwidth: Frequency response extends from a deep 5Hz to an expansive 170KHz (±1dB), capturing the full spectrum of musical nuance.
  
• Precision Stepped Attenuator: Volume control features a highly accurate 192-step attenuator (0.5dB increments), ensuring perfect channel tracking and sonic purity at all levels.
• High-Power Headphone Amplifier: Includes a dedicated 2-watt tube-based headphone amplifier capable of effortlessly driving even the most demanding high-impedance headphones.
  
• Comprehensive Connectivity: Features two pairs of fully balanced XLR inputs and outputs, three pairs of RCA line inputs, and a host of useful controls like Home Theater Bypass and Processor Loop.
  
• Massive Power Supply: Built with a fully regulated, high-capacity power supply and slow-start sequencing to ensure tube longevity and absolute component stability.

Engineered Around the SuperTube

The defining technology of the RP-9 v2 is its four military-grade 6H30P vacuum tubes. Known as "SuperTubes," these valves are selected for their superior linearity and dynamic capabilities, which necessitated an extensive, proprietary redesign of the audio circuit compared to previous models. This fully balanced mu-follower topology extracts the maximum performance from the tubes, translating into a sonic presentation that is smooth, incredibly detailed, and emotionally engaging, with dynamics that rival the finest solid-state designs.

Uncompromised Fidelity and Control

Maintaining signal integrity is paramount to the RP-9 v2’s design philosophy. The output stage features precision MOSFET buffering, providing a super-low output impedance of less than 10 Ohms. This enormous drive capability ensures the RP-9 v2 can handle any amplifier load or long cable run without losing transient speed or control. The use of a precision stepped attenuator for volume control, operating in fine 0.5dB increments, further guarantees that the sonic picture remains perfectly balanced and tonally pure at every listening level.

The Versatile Command Center

The RP-9 v2 is designed to be the central brain of a world-class system. It accommodates all sources with two pairs of fully balanced XLR inputs and three pairs of RCA line-level inputs. Output flexibility is unmatched, featuring two pairs of balanced XLR variable outputs and two pairs of variable RCA outputs, facilitating easy bi-amping or subwoofer integration. Crucially, it includes essential features like a Home Theater Bypass (Unity Gain) for multichannel setups and a Processor Loop for integrating external devices like room correction or equalization units.

Refined Features for the Audiophile

The flagship status is reflected in the RP-9 v2’s luxurious features. An elegant, azure-tinted OLED display provides clear, concise status information, which can be defeated entirely for a distraction-free listening experience. The robust, high-quality chassis is complemented by a solid, machined aluminum 10-button remote control, offering convenient access to volume, input selection, balance, and muting. Slow-start sequencing and auto-mute circuitry are integrated to protect the tubes and power amplifier from turn-on transients.
