Sunfire Cinema Grand Signature Power Amplifier * 5 Channel * 425W RMS
The Sunfire Cinema Grand Signature is a high-performance multi-channel power amplifier designed by the legendary audio engineer Bob Carver. It is primarily known for its immense power output—delivering 405 to 425 watts per channel into 8 ohms—while remaining remarkably cool and efficient due to its unique "Tracking Downconverter" power supply.
Key Specifications & Features
- Power Output: Rated at 405–425 watts RMS per channel into 8 ohms. This power doubles to 810–850 watts into 4 ohms and can reach up to 1,620 watts into 2 ohms on a time-limited basis.
-
Dual Output Options: Features two distinct output types for the front channels:
- Voltage Source: Near-zero impedance for standard speakers, providing tight, controlled response.
- Current Source: Higher impedance (approx. 1 ohm) designed to mimic the warmer, "laid-back" sound of tube amplifiers, often preferred for electrostatic or ribbon speakers.
- Efficiency: Utilizes a Tracking Downconverter power supply that tracks the incoming audio signal and adjusts the voltage accordingly, allowing for high power in a relatively lightweight (43 lbs) and cool-running chassis compared to traditional Class AB designs.
- Energy Storage: The Signature model features massive 800-Joule energy storage (indicated by the front-panel meter), which is nearly double that of the original non-Signature Cinema Grand.
-
Connectivity: Includes both balanced XLR and unbalanced RCA inputs.

Performance & Sound Quality
Reviewers often describe the Signature as a "powerhouse" capable of driving even the most demanding speakers with ease. It is praised for its deep, thunderous bass and clear soundstage. While some modern measurements highlight noise or high-frequency distortion at technical limits, these are rarely audible during typical high-fidelity home theater use.
