The Burson Audio Timekeeper GT4 is a pair of Class AB monoblocks designed to deliver stable and controlled amplification in demanding configurations. Each module delivers 200W into 4Ω, utilizing a power section with EXICON MOSFET transistors biased at high quiescent current to reduce distortion. The integrated power supply, provided by two dedicated Fusion Core blocks, allows for pure Class A operation up to 30W, offering increased linearity at typical listening levels.
Designed for high-fidelity systems requiring significant power reserves without sacrificing signal quality, this design combines Silent Power 2 modules for reduced background noise, a Class A buffer stage to ensure compatibility with any preamplifier or direct source, and a dual-mono architecture to ensure complete physical separation of the channels.
The amplification section of the Timekeeper GT4 follows Burson's traditional philosophy: power, stability, and class AB. Each device is built around EXICON MOSFET transistors, operating at a high quiescent current to minimize distortion while delivering 200W of power. In addition, the Fusion Core power supply stage allows for pure Class A operation in the first 30 watts.


Power supply is a key element in the architecture of the Timekeeper GT4. It incorporates Silent Power 2 modules, discrete regulators designed to ensure a particularly clean power supply. Their role is to drastically reduce the background noise generated by the regulation, allowing the analog stages to operate under optimal conditions. The result is a quieter power supply than that obtained with conventional modules, contributing to the stability and transparency of the audio signal.
The Timekeeper GT4 includes a pure Class A input buffer stage to prevent any incompatibility issues. When activated, it adds 6dB of gain to the input signal, ensuring perfect compatibility with any upstream device.
