The 200W, Class-AB, High-Current Monoblock.
The Timekeeper GT4 monoblock, features GaN Fusion Core, Silent Power Modules, and V7 opamps, setting a new standard in audio amplification!
The Sound of High-Current.
The Timekeeper GT4 combines the best of high-voltage and high-current design for exceptional sound performance. Building on the innovation of the Timekeeper Voyager, the GT4 features an advanced power supply with higher voltage settings. When driving by this higher voltage, its British-made EXICON MOSFET power transistors deliver a sound that is rich, transparent, and dynamic.
The TK-GT4 also uses a high idling current to minimize distortion by keeping transistors in their optimal range. Despite increased heat and power demands, its Cool Case design eliminates bulky heat sinks, while the Fusion Core replaces noisy transformers, outputting pure Class-A within the first 30W.
Fusion Core – Limitless, Low-Noise Power
Unleash the full potential of the Timekeeper GT4 with Fusion Core.
The Fusion Core uses GaN transistors that operate at frequencies ten times higher than traditional silicon MOSFETs, providing superior noise filtering. This advanced technology allows the Fusion Core to deliver ultra-low noise DC power with a robust current pump circuit, offering up to 480W. It is the audio industry’s most advanced power supply, with a matching sleek look.
Quieter than Battery Power.
The voltage regulator is critical for filtering power supply noise, reducing voltage ripple, and providing overload protection. Despite its importance, it is often overlooked in audio circuitry design because it’s not part of the main amplification circuit.
The Timekeeper GT4 features our unique Burson Silent Power Regulator Modules with superior noise rejection rates, ensuring every micro detail in your music shines through with vivid clarity against a pitch-black backdrop. Ready to hear your favorite song for the first time?
The Buffer Stage that Perfects System Matching.
The Timekeeper GT4 includes an optional pure Class-A input buffer stage to prevent system mismatching. When activated, it adds 6 dB of gain to the input signal, ensuring seamless compatibility with any upstream device, whether it’s a high-end DAC, preamp, laptop, or smartphone.
The Most Idealistic Power Amp Design.
A monoblock (one amp, one channel) is the ultimate power amp design, completely eliminating cross-channel interference. This ensures a clean and accurate soundstage that makes every track pop with detail and depth.
GT4, the master of tracks.
Whether you’re a passionate audiophile or simply love immersing yourself in music, the Timekeeper GT4 is the master of tracks. It’s not just a visual masterpiece—it delivers audio perfection! Experience lush vocals, sparkling highs, and dynamic playback that bring your music to life. Get ready for an electrifying sonic adventure with the Burson Timekeeper GT4!
