Perhaps the OP on the other forum should have demo'd a working sample! Perhaps Sound10 could have entered "Marantz PM6004 reviews" into google & seen that several other reviewers gave it between 4 & 5 stars. Perhaps Sound10, you should contact those sites & complain to them as well even if the original post only linked to the WHF review. Perhaps Sound10, you should have realised it was a load of twoddle you have quoted. If it drove RS8s "not very well", instead of "not at all", some credence could be given. WHF have got things wrong but not here!
I took part in a very frank discussion with some of WHF's staff along with other forum members recently where reviews from anywhere were considered to be for the purposes of gaining a shortlist ONLY - neither reader nor writer thought otherwise!
