The Rogue Audio DragoN Power Amplifier is a hybrid stereo amplifier that pairs a tube input stage with Hypex N-Core Class D output modules to deliver 300 watts per channel into 8 ohms and 500 watts into 4 ohms, all from a chassis that weighs just 38 pounds and runs cool enough to place on a shelf without ventilation concerns. Rogue's proprietary tubeD circuit integrates the tube section directly into the amplifier's signal path rather than simply bolting tubes onto a Class D front end, and the result is an amplifier that drives virtually any loudspeaker on the market with authority.
Key Features of the DragoN Power Amplifier
-
300 Watts into 8 Ohms, 500 Watts into 4 Ohms: Hypex N-Core Class D output modules deliver serious current for demanding speakers, planar magnetics, and low-impedance loads
-
Proprietary tubeD Circuit Topology: Rogue's own hybrid design integrates 12AU7 tubes into the signal path, not as a superficial buffer but as an active gain stage that shapes the amplifier's harmonic character
-
Balanced XLR and Single-Ended RCA Inputs: True balanced connectivity for long cable runs and noise rejection, plus single-ended for flexibility
-
Three Massive Linear Power Supplies: Dedicated toroidal transformers for the tube stage, left channel, and right channel eliminate crosstalk and provide clean, independent power to each section
-
No Biasing Required: The 12AU7 input tubes run in a self-biasing circuit, eliminating the periodic maintenance associated with traditional tube power amplifiers
-
Cool, Efficient Operation: Class D output stage generates minimal heat, with standby power measured in single-digit watts
-
Short Circuit Protection: Output stage protection plus slow-start sequencing for the tube section ensure safe operation and long component life
-
Handcrafted in the USA: Designed and built in Brodheadsville, Pennsylvania, with every unit tested, burned in, and auditioned
The tubeD Hybrid Architecture
Most hybrid amplifiers place a tube buffer or preamp stage in front of a solid-state output section, creating two essentially independent circuits that happen to share a chassis. Rogue's tubeD topology takes a different approach: the matched pair of 12AU7 tubes is integrated into the amplifier's gain structure so that the tube section actively participates in shaping the signal that reaches the Hypex N-Core output modules. The tubes handle voltage amplification and contribute their characteristic harmonic texture, while the N-Core modules handle current delivery with a damping factor and slew rate that tube output stages simply cannot match. The result is an amplifier that sounds like a tube amplifier with the grip and control of solid-state.
Power Supply Architecture
The DragoN employs three separate linear power supplies, each built around its own toroidal transformer. One supply feeds the tube input stage, while the other two provide independent, isolated power to the left and right channel output modules. This architecture eliminates the crosstalk and power supply modulation that occur when both channels share a single supply. Each supply uses Rogue's standard high-storage linear design rather than the switch-mode supplies typically paired with Class D modules, contributing to the amplifier's noise floor and dynamic performance. Despite the three transformers, the Class D output topology keeps total weight to just 38 pounds.
Balanced and Single-Ended Connectivity
The DragoN accepts both balanced (XLR) and single-ended (RCA) connections, with true balanced operation from input to output for maximum noise rejection. This makes the DragoN particularly well-suited to systems with long interconnect runs between preamplifier and power amplifier, or installations where electrical noise from other equipment is a concern. The balanced inputs also provide an ideal match for Rogue's own RP-7 v2 and RP-9 v2 preamplifiers, both of which offer balanced outputs.
Speaker Compatibility
With 300 watts into 8 ohms doubling to 500 watts into 4 ohms, the DragoN handles speakers that would overwhelm most tube amplifiers. Planar magnetic speakers (Magnepan, MartinLogan), power-hungry floorstanders, and speakers with complex impedance curves all benefit from the DragoN's combination of high power and high damping factor. The amplifier's ability to deliver current into low impedance loads makes it a natural match for speakers that dip below 4 ohms in the bass region, where many amplifiers run out of headroom.
