Creek Audio is a British based and family-run hifi component manufacturer, boasting over three decades worth of history and professional experience. Creek Audio began in the back bedroom of the family's home, and now reaches all corners of the globe thanks to their well-built distribution network. Creek Audio retain a common design philosophy with every product, and claim that the company was founded entirely on the same three principles; Sound Quality, Build Quality and Honest Pricing. These elements are found within every model of their current catalogue, as well as past models, giving Creek Audio a revered and well-respected name within the hi-fi industry. 

The Evolution 50A is a crucial aspect of the latest generation of Evolution 50 products from Creek. Found within a slim and elegant casing, the aesthetic of the unit is classy and sophisticated, featuring an engraved front panel and solid control knobs. The Evolution 50A is available in black or silver brushed aluminium. This latest release sees improvements on its predecessor in a number of ways, namely a newly developed push-button design developed specifically for this model, allows for a tactile feel and the usable functions are lit to aid in the best possible user-friendliness.

The first series of Creek products to feature an OLED display, the white-on-black display provides a visual clarity and resolution true to its exceptional sound quality. A vast range of customised graphic symbols can also be used with this display and brightness levels are adjustable (or can be turned off entirely) using the menu system.

A large and beastly 250 watt toroidal mains transformer exists as the hear of the Evolution 50A. Not just a brute, however, as the transformer features separate winding designed for high and low current analogue and digital circuitry - offering both vast amounts of power, as well as delicate and detailed control, complete with an optimised power-to-weight ratio and low magnetic interference
