Evolution 5350 continuă cu succes istoria firmei Creek începută in anul 1982 şi este conceput să fie un amplificator excelent pentru orice tip de muzică, aşa încât ascultătorul să aibă ocazia să trăiască experienţa unui sunet cât mai aproape de cel live. In acest sens, Mike Creek a gândit o nouă implementare a etajului de putere astfel încât amplificatorul să fie capabil să furnizeze suficientă putere chiar şi în cazul boxelor cu impedanţă mică. Evolution 5350 este un amplificator onest, construit în vechea tradiţie englezească, ce îşi propune să ofere un sunet bun la un preţ excelent.

- Creek Evolution 5350 integrated amplifier has been designed to fill the gap left by the Creek Classic range, between the entry level Creek Evolution 2 and the top of the range Destiny. It has borrowed technology from both the Creek Evolution 2 and Creek Classic 5350SE and is styled to match the Creek EVOLUTION 2 CD Player and Creek 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.
To enable 2 x 200 Watts into 4 Ohms to be produced from a small case, Creek has developed a massive power supply using a high grade 350 Watt toroidal mains transformer that powers left and right power amp channels separately, plus pre-amp and digital circuits. To keep the power amps operating safely, they are monitored by discrete transistor circuitry to protect against over-current demand, short circuits, over-temperature and DC offsets. Relays mute the input and separate the loudspeaker outputs in case of faults.
