About the Evolution 100A

The Creek Audio Evolution 100A is a high-performance integrated amplifier featuring a Class G output stage that delivers >110 watts per channel into 8 ohms and >170 watts into 4 ohms. It uses four Sanken STD03 Darlington transistors per channel with built-in thermal compensation for low distortion and high current output. The amplifier includes five unbalanced RCA inputs and one balanced XLR input, with modular slots for optional upgrades such as the Ruby DAC (USB, SPDIF, Toslink, Bluetooth, FM tuner), Ambit AM/FM tuner, and Sequel 2 phono preamp. It has two pairs of speaker outputs with A/B switching and a dedicated low impedance headphone amplifier. The front panel features an OLED display with backlit buttons and controls for volume, balance, and tone. The power supply uses a massive 360W toroidal transformer with multiple windings and parallel capacitors for ultra-low impedance and excellent filtering. The amplifier weighs 9 kg and measures 430 x 60 x 280 mm (W x H x D). It consumes less than 20W at idle and up to 500W at full power. The Evolution 100A is praised for its build quality, flexibility, and sound performance that rivals amplifiers costing much more.
