Below we have highlighted two opinions taken from specialist audio forums on the Internet.
OPINION PUBLISHED IN THE"MUNDO HI-FI" FORUM.  

¿Has anyone tried these dampers and if so, what were the results? This is how the debate on the forum began in February 2007. The person asking the question had just bought one of our Prestige units (without shelves) which has a damper at each shelf level, but had yet to try it out. Participation in the debate is extensive and the majority of the participants are sceptical. In April 2007 (2 months later) the same forum member, having now tried out his sound equipment on the new unit, came back to report his experiences and close the debate convincingly with his comments.
