Even after New-Record-Day said that he would be happy to live with the Timekeeper GT3 for the rest of his life, Burson still have the will to further improve it with the GT4.

New Record Day's review of the previous version of Timekeeper GT3
Below are some details taken from Burson's website presentation page, https://www.bursonaudio.com/products/timekeeper-gt4/:
"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".

Dual Power Supply - Burson Fusion Core X 2 (32V/15A)
Key Features:
Below are some thoughts coming from EXICON manufacturer about what makes these powerful transistors being one of the best choices in building High Fidelity Amplifiers:
"The Exicon range of lateral MOSFETS were specifically developed for high performance linear amplifier applications. They are capable of very high standards of amplification, with low distortion and very fast slew rates.
Completely free from secondary breakdown and thermal runaway they are extremely reliable.
In addition they have a number of characteristics which make them ideal for audio amplifiers, such as negative temperature coefficient for sharing current without the need for source or drain resistors, and simple drive requirements resulting in fewer components in the audio path".

Design:
- Cool Case Design:
- Eliminates the need for bulky heat sinks.
- Optional Pure Class-A Input Buffer Stage:
- Ensures optimal system matching, adding 6 dB gain when needed.
- Monoblock Design:
- Eliminates cross-channel interference for a clean, accurate soundstage.
Inside the High End Timekeeper monoblock we have a nice & clean design with six big
EXICON output transistors for each monoblock
