Please can someone explain why the 32LH7000 gets a more favourable review than it's bigger 42" brother? I would have expected the only difference to be the size - is this not the case or do the reviews just vary due to different reviewers own opinions?? One example of this is the fact that the speakers/sound on the 42" version generally gets slated but the What Hifi review of the 32" set sounds quite decent.
