Welcome to Peak HiFi

Peak HiFi is a well established business and was formed in 2004 as audio consultants specialising in high quality audio equipment, with a particular fondness for stereo and analogue equipment, we are particularly enthusiastic for classic turntables such as the Garrard 301 and the Garrard 401. Peak HiFi offers a select range of new and approved used equipment, accessories and services.
