Burson Timekeeper Voyager: Class AB power amplifier with high current efficiency

The Voyager is a Class AB power amplifier designed for high current efficiency, delivering up to 200 W per channel at a 4 Ω load.

Burson Audio has integrated a range of proprietary technologies into this model, as stated by the manufacturer. Key features include an enhanced MCPS (Max Current Power Supply) system equipped with Silent Power 02 (SP02) regulators, a discrete input buffer utilizing Supreme Sound V7 Vivid operational amplifiers, an output stage powered by EXICON MOSFET transistors, a Cool Case enclosure, and the option to choose between Super Charger or Fusion Core power supplies.

The Timekeeper series of speaker amplifiers has been under development by Burson Audio for more than fifteen years. The latest Voyager model is designed to operate at a high idle current, which allows the transistors to work within their most linear range, thereby minimizing distortion.

Although it consumes over 100W at idle, the Voyager achieves Class AB performance in a compact design, rivaling much larger amplifiers.

Key features include:

• MCPS (Max Current Power Supply) – Operates at an increased voltage frequency of 170 kHz (compared to the traditional 50 Hz), shifting noise to a range beyond human hearing.
• Silent Power 02 (SP02) Regulators – Proprietary power regulators that are claimed to be up to 200 times quieter than conventional alternatives.
• EXICON MOSFET Transistor Output Stage – Designed for efficient and precise power delivery.
• Class A Input Buffer – Uses Supreme Sound V7 Vivid discrete operational amplifiers, allowing for a 6 dB gain in the input signal.

The Voyager’s standard model is equipped with compact Super Charger power supplies rated at 32 V/7 A. For those seeking enhanced performance, a premium Max version is offered, which includes Fusion Core power supplies rated at 32 V/15 A. The manufacturer asserts that this upgrade allows the amplifier to reach its maximum capabilities.

Burson Audio characterizes Fusion Core as a sophisticated power supply that employs GaN (gallium nitride) transistors. These transistors function at a frequency that is ten times greater than that of conventional silicon MOSFETs, leading to improved noise filtration and resulting in clearer audio and a more subdued background in recordings.

 

Sold in pairs, the Burson Timekeeper Voyager monoblocs are now available to order in two versions:

• Standard with Super Charger power supplies (32 V/7 A) at a price of $5,800
• Max with Fusion Core 32 V/15 A power supplies) for $7,000
