13A UK styled mains plugs can be found on every appliance and electrical product in every home in the British isles and farther away places. Many of which are generally moulded and fixed to the factory built and supplied power cords on household appliances, normally found in your kitchen and bedrooms. No good for the likes of anyone wishing to upgrade their mains power cord supplying their HI-FI kit.
Manufactures of audio and video equipment are wise to install IEC outlets which lend themselves greatly to cable upgrades, as long as the correct connector is used then the world is your very oyster. UK styled 13a plugs are not as common as IEC type connectors but TM3Connections has stock of what we believe to be the best available.
