200W GaN Fusion Core mono-block

The Timekeeper Voyager is a fully discrete, high-current Class-A mono-block power amplifier delivering 200W into 4Ω — a compact powerhouse built to take control of demanding speakers from brands like Dynaudio, Bowers & Wilkins, and KEF. With its GaN Fusion Core power supply, Silent Power 2 regulation, and V7 discrete opamps, it brings quiet backgrounds, explosive dynamics, and stable control to a modern stereo chain without adding complexity to your rack.

High-current Class-A power that stays in control

The Timekeeper Voyager is designed around high idle current — over 100W at idle — so the output stage spends more time in its most linear region. That means less crossover distortion, more stable transients, and a cleaner window into recordings. In practice, you hear firm bass lines, uncompressed dynamic swings, and a sense of ease at any level. Tough loads and low-sensitivity speakers become predictable rather than finicky, giving you a system that feels confident instead of fragile.

Cool Case chassis for silent thermal management

Running a Class-A mono-block that idles above 100W usually means large fins and fan noise. The Voyager’s Cool Case design uses the full enclosure as a heat-dissipating structure — distributing thermal energy across the chassis so it runs stable and quiet. No external fans, no moving parts, no hum. You get the advantages of Class-A behavior along with a compact, copper-gold and space-grey enclosure that is easy to place in a rack or on a low board.

GaN Fusion Core power supply

Instead of a traditional transformer-based supply, the Timekeeper Voyager uses a GaN Fusion Core with next-generation gallium nitride transistors. It delivers up to 480W of ultra-clean power at a 1MHz switching frequency, which moves switching noise far above the audio band and simplifies filtering. In practical terms, that means lower residual noise than many linear supplies and an ease to dynamics that comes from substantial current on tap. Compact, stable, and efficient — the Fusion Core is designed specifically for high-end amplification rather than general-purpose electronics.

Silent Power 2 regulation and ultra-low noise floor

Power supply regulation sets the stage for noise performance. Silent Power 2 modules in the Voyager bring the noise floor down to an ultra-low 0.8μV, making the amplifier roughly 200 times quieter than typical regulator designs. That noise performance matters when you combine high-gain amplification with modern high-resolution sources. Quiet passages stay quiet. Reverberation tails remain intact. You hear fine spatial cues instead of background hiss.

V7 discrete opamps for fine-tuned system matching

At the input stage, the Timekeeper Voyager uses Burson’s V7 discrete opamps and a switchable Class-A buffer to handle real-world sources. Engaging the buffer adds approximately +6dB of gain, giving you flexibility when working with DACs, preamplifiers, streamers, or compact sources. That adjustability keeps level matching simple and helps you run source devices in their optimal output range instead of forcing them near their limits. The result — stable gain structure and predictable volume control from track to track.

Mono-block architecture for imaging and separation

Because the Timekeeper Voyager is a true mono-block design, each channel has its own chassis, power supply, and signal path. This physically isolates left and right channels, reducing crosstalk and shared-current artifacts that can blur imaging. Stereo playback takes on a more three-dimensional quality — stable center vocals, precise lateral placement, and a sense of depth that holds together across listening levels. It is a straightforward way to give a two-channel system more spatial definition without changing speakers.

Engineered for modern loudspeakers

With 200W into 4Ω and a high-current Class-A topology, the Voyager is tailored for contemporary loudspeakers that demand both current and control. Whether you are driving compact stand-mounts with low sensitivity or multi-driver floorstanders that like current, the amplifier has the headroom to keep bass aligned and treble composed. This makes it a strong partner for well-known brands like Dynaudio, B&W, and KEF, and a practical choice for listeners who change speakers over time but want to keep the amplification stable.

Refined measurements with musical intent

The Voyager balances measurement discipline with real-world listening. A frequency response of 0–58kHz (±1dB) ensures bandwidth well beyond the audible range, while total harmonic distortion stays below 0.0015% under typical conditions. An input impedance of 40kΩ makes it easy to integrate with both dedicated preamps and DACs with variable output stages. The aim is straightforward — low coloration, consistent behavior across different sources, and an amplifier that does not dictate tonal character but lets your speakers and recordings lead.

Designed to stay in your system long term

The Timekeeper Voyager is built as a long-term anchor component rather than a temporary upgrade. Its mono-block format, GaN-based power supply, and discrete gain stages give it a clear role in a two-channel chain, and its power reserves leave room for future speaker changes. Whether you are assembling a focused near-field system or a full-room stereo, it provides the stability and current delivery that make everything else easier to dial in.
