Raoul Trifan of Audiophile Dex reviews the Burson Timekeeper GT4 monoblocks in the Max package with two Fusion Core power supplies. He also opens one up to show what is inside.

Setup

Raoul used a Burson Conductor GT4 as the preamp and source, linked to the Timekeepers with 12V trigger cables, and placed the amps in a Burson Mothership rack. Input and gain are selected with buttons on the rear, and the LED colour shows the current mode. He found the six small fans virtually silent.

Noise and Temperature

With his ear against a 92.5dB tweeter, Raoul heard no hum or hiss. In the rack, the amps ran at about 43°C, staying under 50°C.

Timekeeper GT4 Sound: Warm, Not Clinical

Raoul describes the sound as pleasant and warm rather than clinical. At the same volume, he heard more detail than from his Marantz and Yamaha amplifiers. His listening stayed below 30W, within the Class A region, and he found the amps non-fatiguing over hours.

Inside the Timekeeper GT4

  • Exicon lateral MOSFETs, six per monoblock
  • Max Current Power Supply (MCPS) regulation and Silent Power regulators
  • A speaker protection relay and DC detection
  • An optical sensor that shuts the amp down if the lid is opened
  • Polymer capacitors and soft rubber feet

Drawbacks

  • A slight whine from the power supplies at power-on, which Raoul considers normal
  • The fans are faintly audible up close
  • About 100W of power draw at idle
