Reviewers should absolutely able to set up a system. And they should have equipment commencerate with the room and power. I have no problem with a reviewer using a NAD integrated in a living room situation. The reviewer should be able to pull the speakers out and get the most from the room. But VAC ref equipment or of similar should be in a room designed to reproduce audio at a high level. And I expect the manufacturer to assist in initial setup. But the reviewer should have skills to fine tune on his own to be taken seriously.
