Switchable from 115 Volt 60Hz to 230 Volt 50Hz Operation.
Housed in a slim case with engraved front panel and solid HiFi Choice Awardcontrol knobs, The Creek Evolution 50A V2 Integrated Amp is finished in a beautiful black brushed aluminium. An ingenious new push button design has been developed for the 50A, offering excellent tactile feel and backlit optical indication of usable functions for optimum user-friendliness.
This is CreekÂ’s first product to feature an OLED (Organic Light Emitting Diode) display. This white on black display provides higher clarity and resolution than a normal display. Brightness levels can be changed or the display made to turn off when not required, via the menu system.
At the heart of any good amplifier lies a good power supply; The Creek Evolution 50A uses a 200 Watt toroidal mains transformer with separate windings for high and low current analogue and digital circuitry. This solution produces a good power to weight ratio and low magnetic interference. CreekÂ’s policy of paralleling several low impedance capacitors to create an ultra-high specification capacitor to smooth the DC also helps to produce a very powerful and accurate sound from such a relatively small amplifier.
Creek’s Senior Engineer – David Gamble – has much experience in the audio industry. He has developed a completely new bi-polar transistor power amplifier circuit especially for the EVOLUTION 50A with very high open-loop gain and low distortion. Featuring a pair of Sanken 15Amp power transistors, with built-in thermal compensation for rapid bias tracking performance, the Power Amplifier circuit has very low output impedance and can produce high output current. This combination will provide exceptional speed and control over most loudspeakers.
David also developed a completely new analogue Pre-amp circuit, providing high levels of flexibility and control, via unbalanced or balanced inputs. It has multiple input options, switched electronically or via gold contact relays, plus electronic Volume, Balance and Tone controls. For Vinyl fans, a Sequel Phono pre-amp can be plugged-in, substituting Line Input 1 for Phono. In addition, there is another input available, should the user want to fit a Tuner module. The computer control will sense this and respond accordingly.
Excellent measured and sonic performance has been achieved with this Creek Evolution 50A Integrated Amp, but when using digital input signals via the matching EVOLUTION 50D CD/DAC/Pre-amp, the analogue pre-amp can be bypassed completely. The EVOLUTION 50D CD/DAC/Pre-amp has a very high-end volume control in the digital domain and ‘Class-A’ balanced audio outputs. Connecting the output directly to the “Power amp direct” inputs elevates the performance to an even higher level.
