I have been reviewing hi-fi for a couple of decades now, with endless hours spent in the What Hi-Fi? test rooms putting everything from audiophile headphones to stereo amplifiers through their paces. But my testing hasn’t always been confined to What Hi-Fi? HQ.

There have been occasions where I have swapped four walls for four wheels to listen to a number of different in-car hi-fi systems.
