While most amps rely on a combination of multiple output transistors to achieve their amplification ‘oomph’, we 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. The thing is, they’re an investment. But it’s an investment worth making and here’s why.
The more common approach of combining multiple output transistors (sometimes as many as 48 per channel) comes with some major sonic and technical compromises. Compromises that we simply aren’t willing to make. Think of it like multiple voices in a choir. No matter how talented or well-rehearsed the singers, the pitch and speed of each voice will vary fractionally, affecting the overall timing, clarity and dynamics of the sound. Similarly, no two transistors are exactly alike and so combinations of multiples will require all kinds of technical workarounds to combat ‘sonic smearing’. But the trouble with technical workarounds is that they tend to introduce yet more potential for sonic smearing. So a powerful amplifier built with 48 transistors is more likely to sound like a choir than one clear and consistent voice.
Gamut amplifiers use just one Herculean transistor per phase. What’s more, rather than using one NPN (negative-positive-negative) and one PNP (positive-negative-positive) transistor for each of the two channels, we stick with closely matched NPNs all-round. 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.
