At the heart of any high-end amplifier there must be a good power supply; The Creek Evolution 100A uses a massive 300 Watt, low profile, toroidal mains transformer, with multiple windings for high and low voltages and current, to separate the power amp, pre-amp and digital circuitry.
Creek’s long-standing design policy of paralleling several small capacitors in the power supply creates an ultra-high specification capacitor, with low inductance and ultra low impedance. This significantly improves filtering and helps produce a very powerful and accurate sound from such a relatively small amplifier.
After testing several methods of building a high performance and high efficiency power amplifier, suitable for this new model, David Gamble – Creek Audio’s Senior Engineer – created a unique Class G circuit especially for the Creek Evolution 100A. David chose to use four Sanken STD03 complimentary power Darlington transistors per channel, as used in theCreek Evolution 50A, which feature built-in thermal compensation.
Compared to the Creek Evolution 50A, the improved the performance of the voltage gain circuitry, which, in combination with the output stage, now achieves extremely high open-loop gain and exceptionally low distortion, without sacrificing stability. The result is an exceptional power amplifier circuit with very low output impedance and high output current capability. This combination provides exceptional speed and control suitable for driving most loudspeakers.
To increase the power output of the smaller Creek Evolution 50A, yet still retain the same case size, David Gamble developed a cunning Class G circuit which runs normally at a lower voltage for power levels up to 25 Watts into 8 Ohms. When required to produce more than 25 Watts, the amp automatically swings to a higher secondary voltage, to increase the output power capability to over 100 Watts into 8 Ohms.
'This is one of the most powerful amplifiers I have heard at the price...its not just a bruiser though. It’s actually a highly finessed performer, with a very attractive nature that doesn’t draw attention to any single part of the frequency band. Tonally it is clean and open but nicely rounded. Cue up Kate Bush's Wow, and you’re greeted with a smooth and warm sound, just as it should be. Her voice is carried beautifully, with real delicacy and intimacy. So many solid-state amplifiers just cannot do this, managing to lose the sense of closeness that the recording offers' (Hi-Fi Choice Magazine March 2015)
'Another way the 100A betters its sibling [the Creek Evolution 50A] is its ability to convey multiple stands in the mix. For example, spin up The Teardrop Explodes' Treason, and it seems better able to cut through the densely layered and highly compressed recording, to reveal individual instruments playing. There’s a superior sense of the space around those instruments too; they don’t seem to be packed together like sardines...it has a commendably wide soundstage that stretches well from left to right. Within this, instruments are tightly located; I'm also impressed by the power of the vocal line...behind this, toward the back of the recorded acoustic, there’s a good deal of subtle, low-level detailing' (Hi-Fi Choice Magazine March 2015)
'They say it’s hard to buy a bad car these days. That’s as maybe, but its products like the Evolution 100A that make you think the same might be happening with hi-fi! Its certainly not an inexpensive amplifier, bit it is genuinely multi-talented and gives an excellent performance across the board. The idea of the new Evolution series is to offer greater flexibility and operational refinements, while retaining serious sound quality. A year or so ago, the 50A succeeded in this, and now the 100AS goes further still. Here is an extremely versatile yet highly accomplished sounding product; factor in the good standard of build and finish, and it is hard not to recommend. It’s an essential audition for those looking for a superb sub-£2000 integrated' (Hi-Fi Choice Magazine March 2015)
