About the Cinema Grand
The Sunfire Cinema Grand is a high-performance five-channel power amplifier originally released around 2001. It delivers 425 watts RMS per channel into 8 ohms with a frequency response of 20 Hz to 20 kHz and total harmonic distortion of 0.5%. It features a sophisticated power supply with large capacitors and a toroidal transformer in later versions, providing 480 joules of energy storage for stable, dynamic performance. The amplifier offers both voltage-source and current-source outputs on the front left and right channels, allowing optimal matching with various speaker types including electrostatic and ribbon speakers. Its design emphasizes a multilayered, three-dimensional soundstage with clean, uncolored sound and extremely low noise, making it suitable for demanding home theater and high-fidelity audio applications. The Cinema Grand Signature version improves on the original with a larger power supply, enhanced signal-to-noise ratio, and a higher power output of 425 watts per channel at 0.5% THD, positioning it as one of the most powerful multi-channel amplifiers available. Dimensions are approximately 19" wide x 6.5" high x 15.75" deep, and it weighs about 45 pounds.
