D3i dual mono preamplifier

Naturally articulate

A preamplifier manages the critical task of preparing a delicate audio signal for power amplification. While this may not sound like the sexiest job in your hi-fi system, a surprising amount of your listening bliss rides on getting that task bang-on.

Remember the last time you heard your favourite music ‘unplugged’? That pure, organic live sound with absolutely nothing in the way. That’s what a really great preamp should sound like. Naturally clear and coherent. Articulate and eloquent. Lucid and fluent.

The D3i is a truly skillful communicator, deftly designed to prime the delicate audio signal for such greatness.

So when you pair it with a great quality power amp, you can expect to hear a whole world of sweet detail in your music and feel its vividly immediate presence.

And if vinyl is your thing (it’s certainly ours) the D3i is handily designed to take an add-on phono stage board.

The Gamut sound

Where power meets precision and timing is everything

Power and precision, while not quite opposites, are often thought of as ‘either/or’. If you have one in spades, chances are you’re a bit less endowed with the other. When it comes to audio amplification, this poses a dilemma. Time then, for a radical rethink.

The solution, while not easy, is deceptively simple (the best solutions usually are). It’s also what sets Gamut amplifiers apart.

While most power amps rely on a combination of multiple output transistors to achieve their amplification ‘oomph’, our power amps use one single output transistor per phase, hence two per channel. That’s it. No rows of multiple bipolar transistors. Stunningly minimal and an absolute winner performance-wise. Of course we’re not just talking about any transistor. These guys are massive – imposingly robust and immensely powerful (they can handle a peak current demand of 300 A and 100 A continuously). What’s more, the particular models we use are rare in hi-fi – you won’t find them in too many amps.

To feed such a power amp, you need a signal that’s up to the job – clean, clear, dynamic and fully able to handle the formidable speed and resolution it’s about to meet. The Gamut D3i preamplifier was developed to deliver that very signal. It features a balanced, low noise J-Fet design. Dual mono, of course. Even the volume control circuit is a custom-built low impedance design, created to lower noise levels an additional 20dB compared to conventional circuits.

All of which enables our amps to meet our famously exacting standards for uber-precise timing, stunning clarity and vivid dynamics. In other words, to deliver that signature Gamut sound.

But don’t just take our word for it. Come and have a listen. We think you’ll love what you hear.

Every little thing auditioned

Every component in a Gamut amplifier is of the highest quality and has been hand-selected following intensive listening tests – from the circuit boards, via the non-magnetic chassis, to the superlative XLR connectors. No expense is spared.

So when you buy a Gamut amp you’re not paying for our brand name or for a swanky office in the best part of town. You’re investing in what goes into your amp, pure and simple.

We think you’ll hear the difference. Why not come and have a listen and judge for yourself?
