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. Reconditioned Garrard 301 and 401 units are available as well as beautifully engineered plinths for these decks. We welcome you to visit us at our premises on the North Eastern edges of the Peak District and take advantage of our relaxed surroundings and two demonstration rooms where we can demonstrate all of the equipment and assist you with your selection. Please call us to fix an appointment.
