PA3

 Gen3 Class A+AB Design – Features ultra-low distortion, high-bias circuitry, and slides into Class AB only under extreme loads for clean, efficient power.

 Front-Channel Focus – Tailored for LCR or front 5 channels in high-end theaters, delivering uncompromising performance where it matters most.

Robust Engineering – Equipped with a massive capacitor bank, fully balanced architecture, and advanced thermal management for consistent, high-output operation.

With PA3 we proudly introduce our third generation or renowned Class A+AB amplifiers. We have long been aware of the importance of power amplifiers—as an engine-like device in the signal path, its performance crucial to the playback quality of the entire system. This Gen3 Class A+AB amplifier has lower distortion, a more robust power supply, and superb sound quality. With investment in home theater components, we realize that in many cases customers need the flexibility to favor the most important channels. The LCR or 5 front channels of multi-channel systems are undoubtedly the most important. PA3 was born for this application: bringing Starke Sound’s unique Class A+AB amplification into our ultimate P Series products. A huge capacitor matrix ensures abundant power, as well as a fully balanced circuit and a thermal management system. PA3 has an extremely high-biased design that maintains Class A operation for nearly any musical or audio signal. We allow the amp to “slide” into Class AB but only at extremely high output levels. This ensures both low distortion and high efficiency. PA3 delivers uncompromising power “front and center” to premium private cinemas.
