Unison Research Performance

This amplifier is designed to balance the classic, rich warmth associated with vacuum tubes with the precision and clarity required for modern high-fidelity systems. Because it operates in Pure Class A, you get a fluid, organic soundstage that emphasizes the emotional nuance of recordings without sacrificing detail.

The Performance delivers 40 watts per channel. While this is plenty for most high-fidelity setups, it is best paired with speakers of moderate to high sensitivity to fully realize its dynamic potential.

This specific circuit design is what allows the amplifier to achieve its unique sound. By using three tubes in parallel for each channel, it maintains the purity of a single-ended design while providing the necessary power output to drive a wider range of speakers effectively.

No, the Performance is an integrated amplifier, meaning it combines both the preamplification and power amplification stages in one chassis. You can connect your source components, such as a CD player or DAC, directly to its line-level inputs.

Like all tube amplifiers, the vacuum tubes will eventually need to be replaced as they age and lose their performance characteristics. The unit uses a standard complement of 6 x KT88, 2 x ECC82, and 2 x ECC83 tubes, which are widely available and relatively straightforward to swap when the time comes.

The Performance features four line-level RCA inputs, but it does not include a built-in phono stage. If you plan to use a turntable, you will need to connect it to an external phono preamplifier before plugging it into one of the line inputs.
