We play a lot of music, and we play it loud. But we don’t just listen to the speakers; if there are special features then we make sure we fiddle with them until we’re satisfied. Of course, it always comes back to the music. Radios are tested by reviewers who have a knowledge of sound quality, as well as a context of the market. We’ll listen to radios alongside similarly priced rivals, so when we recommend a particular model, it’s among the best you can buy for the money.
