What Hi-Fi? turns 40 this year, and to celebrate we’ve filled the latest issue with 50 extra pages, in which we look at some of the best products - and the flops - of the past 40 years. There’s the usual selection of First Tests, a three-way stereo speaker showdown and a round up of wireless radios, plus the chance to win £20,000 worth of kit! All this and more in the must-have 40th Anniversary issue.
