GamuT S300

The GamuT S300 dual-mono power amplifier contains four 2,500VA mains transformers for a total of 10,000VA, eight rectifiers, and twenty 22,000uF large RIFA capacitors for a total of 440,000uF. 

This is split into two independent amplifier sections, one for each channel.

Each channel has a dedicated mains power cord and power switching, providing true dual-mono operation, and twice the power by using two independent normal wall sockets.

The GamuT S300 delivers 300W in 8ohms, 600W in 4ohms, and a scarcely believable 1,200W in 2ohm, but only if the mains supply in your home will allow high enough currents. This means not just the breaker switches, but more importantly that the copper wiring in the walls is dimensioned thick enough.

It uses a new higher-power version of our single MOSFET and oversized heatsinks to ensure the temperature is kept low. 

The transformers have a combined weight of 60kg (132lbs), and are mounted on a 3mm thick steel plate floating on 8 industrial vibration absorbers to prevent mechanical noise.

The chassis and top plate are made of 20mm (¾”) thick plates of aluminium to keep the weight within reasonable limits.

The six round items are custom made locking screws holding the top plate in place.

However, an S300 still weighs in at 233kg shipping weight (512lbs). So we do recommend asking 4 strong men to help you when you want to move this amplifier.

The amplifiers are available in silver look. Engraving of text and logo can be added to suit your individual style and taste. Serial number and owner’s name or monogram can be added to the top plate to discourage theft - however, the weight alone might do that.

As for the sound quality, we hope to live up to the remark in TAS: "If they sounds as good as they look in pictures, these things will eliminate much of the competition". The first test from Brazil seems to confirm it.

In the absolute sound issue 139 page 18, Editor Robert Harley wrote about our room with two GamuT S300 driving Nearfield Acoustics Pipedreams Reference 18 in the Hi-Fi Show and AV Expo Heathrow 2002: 

"This room was clearly the best sound of the show - and by a wide margin".
