Creek Evolution 5350 1-Channel Amplifier

Creek Audio Limited Evolution 5350 2-Channel Integrated Amplifier

The Evolution 5350 integrated amplifier has been designed to fill the gap left by the Classic range, between the entry level Evolution 2 and the top of the range Destiny. It has borrowed technology from both the Evolution 2 and Classic 5350SE and is styled to match the EVOLUTION 2 CD Player and EVOLUTION Tuner. Creek Audio has developed a completely new high current bi-polar power amplifier to enable it to drive low impedance loudspeakers with modern dynamic music from high resolution sources. This has required a radical approach to enable it to be fitted into a slim-line case. Each power amp is now built as a module, using a high proportion of Surface-Mount components, on a double sided PCB, bolted to a massive 18 fin heatsink. This means both channels are identical and can be fitted and removed easily for servicing if required. The power amp topology includes a cascoded differential voltage amplifier and MOS-FET current drive stage feeding a double Darlington output stage with four high-current bi-polar transistors to produce a very powerful amplifier capable of driving the most demanding of loads, with high resolution and accuracy. DC stability is maintained by a servo amplifier that rejects DC and allows the amplifier to be coupled directly without capacitors. In a further development of the Evolution 5350 integrated amplifier's pre-amplifier section, 5 inputs are selectable by high current gold plated relays and switchable access to the power amp allows the Evolution 5350 to be driven directly by the front channels of a 5.1 AV receiver. The standard Creek plug-in Phono pre-amp is also featured. A high-grade PGA2320 digitally controlled analogue volume control circuit together with OPA604 Op-Amps are used to provide a pre-amp with higher overload margin and lower distortion.
