SPL Performer s900 Stereo Power Amplifier

A Design That Reflects Taste and Precision

The SPL Performer s900 stereo power amplifier is a perfect fit within the SPL “Professional Fidelity” HiFi product line, blending seamlessly with its sophisticated aesthetic. Available in three timeless finishes—black, red, or silver—it exudes elegance and understated style.

A Class of Its Own

Traditional solid-state power amplifiers often operate at the limit of their components, leading to unwanted harmonic distortion. Tube amplifiers, while offering a unique sound, also introduce distortion at high levels, though their characteristic behaviour softens the harshness. However, both still result in a skewed representation of the sound.

With the groundbreaking VOLTAiR Technology, the Performer s900 can handle much higher levels of power without pushing components into their critical range. Each component operates within its optimal parameters, delivering a sound that is natural, relaxed, and free from distortion. The result is a deeply enjoyable listening experience—rich in detail and without fatigue.

Uncompromising Power

The Performer s900 features separate amplification stages for voltage and power, ensuring seamless operation of its class-AB amplifier circuit. Thanks to independent feedback paths for each stage, the feedback from the speakers does not interfere with the input stage, allowing VOLTAiR technology to perform at its peak.

This combination of advanced technology and precision engineering creates not just a hi-fi system, but an experience that satisfies both the technical perfectionist and the emotional music lover.

Flexibility and Compatibility

The Performer s900 offers both XLR and RCA stereo inputs, making it compatible with virtually any preamplifier on the market without the need for adapters. You can easily switch between the inputs using the Input Select switch located on the rear panel.

Customisable for Your Setup

When we say "fit," we mean perfectly adapted to your preferences. The Performer s900 allows you to adjust the input sensitivity in 0.5 dB steps, from 0 dB to -5.5 dB. This fine-tuned control is more audiophile-friendly than the standard panorama potentiometer found on many preamplifiers, enabling you to match the output perfectly with the input levels of your preamp and speakers.

Power and Versatility

The binding posts on the Performer s900 are designed to accept both banana plugs and stranded wire up to 4 mm in diameter, making it compatible with any common speaker cable. However, we recommend not using speakers with an impedance lower than 2 ohms.

Intelligent Control and Protection

The Performer s900 features an AMP CTL connection, allowing you to control its standby mode through compatible preamplifiers like the Director Mk2, Elector, Phonitor x, or Crossover. You can also use third-party preamps with a 12V trigger input to toggle the amplifier’s standby mode.

To ensure safety and longevity, the Performer s900 is equipped with a DC voltage protection circuit and a temperature sensor that monitors heat levels. If DC is detected, the output stage automatically switches off, and the Protect LED will light up red. If the amplifier overheats, the TEMP LED turns yellow, and the output stage is disabled until it cools down.

Crafted for Sound Excellence

Every component in the Professional Fidelity series is chosen not only for its technical specifications but also for its sound. Many crucial components are installed using Through-hole technology, allowing us to select the best-sounding parts for an unparalleled listening experience.

VOLTAiR Technology: A New Standard

At the heart of the Performer s900 is our exclusive VOLTAiR technology, which operates with a 120V DC voltage—four times the standard voltage of traditional IC-based op-amps. This revolutionary technology is made possible by the SPL 120V SUPRA operational amplifiers, designed to handle extreme voltage without damaging the components.

With this 120V technology, we achieve exceptional dynamic range, signal-to-noise ratio, and headroom, translating into a level of sonic detail and musicality that is simply unmatched. Whether it’s the technical performance or the sheer emotional depth of the sound, VOLTAiR ensures that your listening experience is always relaxed, engaging, and utterly captivating.
