Reviews. They are just a guide. They are not the definitive answer and being an 'expert' doesn't make any reviewer better at judging how good a piece of hi-fi equipment is. The best judge, by far, is the prospective purchaser.
What can happen, all too easily, is that a small number of products can get lauded above all others and purchasers risk missing out on less celebrated products that might suit better.
Don't be afraid to explore products that haven't had 5-star reviews or to walk off the beaten track. Brands like AstinTrew, Sugden, Audio Analogue, Aurousal and Icon Audio make some excellent kit. Likewise some brands that don't have snob value like Marantz, Creek, Rega, Yamaha, and Denon, make some superb components that are every bit as worthy for consideration as the oft referred-to Naim, Roksan, and Cyrus.
Hi-fi is a broad church and doesn't have to be defined by the latest obsessions of the reviewers.
