Hi all - I see that the Omega E mat thread has had a "reset". Please don't go berserk but I think its only fair to the reader if you tell us whether or not you actually purchased the mat at full price. If you were sent mat(s) free of charge or at a reduced rate with no expectation of them being returned that should be disclosed. For instance, tommylion the 4 mats you discuss you paid $2,400 for and you are not returning them?
About a year ago, Audiocircle had a similar issue come up. Burson Audio was sending people cables free of charge with no expectation they be returned. A number of favorable reviews were published which ended-up being taken down because the board facilitator believed it was a form of payment to the people who wrote the reviews.
