KEF LS50 - Question

I remember hearing a YouTuber or two talk about why some products get so much attention. In part, some companies can afford to ship out samples for review; then, there's a kind of group-pressure effect among reviewers to weigh in  on something another one has done. This undoubtedly affects search engine results and there is a cascade effect. 

Sometimes a reviewer like Guttenberg will get smaller manufacturers to send him gear; those reviews are especially helpful because they break the logjam created by the bandwagon effect above. Of course, forums like this are great for spreading the word for smaller companies, but most people won't see this on their radar or won't know exactly how to interpret results from a forum with hobbyist-speak.
