I always read professional reviews, but in the end, I prefer the AH forum feedback on the products before I make a final purchasing decision. By simply asking a specific question, I can get a wider breadth of information on a specific product feature than a professional review, and usually, if there are problems, members can also chime in on customer support.
I just today ordered an AVR based on personal experience with the brand, but moreover, the good experiences of others on the AH forum with the specific product.
