Review: Marvellous little audio selectors

I am impressed by the high quality, ease of use and low prices of Yourspares Electrovision Turntable Pre-Amplifier and Electrovision 4-Way Audio Input Selector (both stereo). The latter model, being a direct switch, can also be used in reverse - to select which other device a stereo output signal should be sent-to. I am using two of these to send and receive audio signals between my analogue mixer and the sound card on one of up to four selectable computers. These units are also available from some big suppliers but at a much higher price. Yourspares saves me money and delivers quickly.
