Vacuum tubes is the ideal technology for high end audio. Their inherent linearity aids in keeping design simple and the sound reproduction quality higher than solid state amplifiers.

Vacuum tube ( or ‘valve’) amplifiers can be roughly divided into two categories: single-ended and push-pull. We have products in both categories.

As a boutique amplifier manufacturer, we can design with your speakers in mind. Contact us for a personal design that fits in with your current hifi components.

Usually your loud speaker sensitivity determines the power needed. If your loudspeakers have a SPL rating of more or equal to 94 dB/watt, a single-ended design might be the amplifier of choice. For SPL ratings below 94 dB/watt push-pull amplifiers are more suited. Ultimately your ears are the best judge. Some clients with lower sensitivity speakers still prefer the single-ended sound.

Some amplifiers are available as kits too.

We offer three finishes on chasses and enclosures: black, ash grey or brushed stainless steel.

All amplifiers can be supplied with a protective cage at extra cost. The stylish cage protects the tubes and offers safety to children and pets in home environments.

We can accommodate buyers who need flexible payment options.  Contact us to make an arrangement. Manufacturing commences once 66% of full price has been settled.

Mars Buffer

The need for a buffer to add a tube to your signal path, without adding gain is now bigger than ever. With DAC’s (Digital Analogue Converters) being so popular, a common problem occurs. The DAC output is too high, and your amplifier plays music at maximum as soon as you turn the volume to 1. To the rescue comes the attenuator with a tube buffer. No matter what attenuation you select, the signal is not degraded and the magic sound of the vacuum tube makes your music sound the way it should.

The design is a cathode follower with a current source

At Mars Tube Audio we have the experience, knowledge and skill to hand craft audio gear that sounds excellent. We manufacture and offer support from our workshop in Paarl, South Africa.


Our workmanship is guaranteed for three years, and the tubes we supply for 6 months from sale date. All support is offered from our Paarl workshop.
