I'm happy that these people have not heard differences, but I have heard GREAT differences between mine old Technics and mine new Aeron... so big that initially I had much difficulties to get habit with the new sound. In fact the second, as I said, is more detailed, bright and neutral, the Technics was warmer and a bit muffled.

Could be that Technics component are much cheaper but I haven't spoken of an equal 'setup', I have compared two very different brands and eventual technology.

Who are those that says Rotels are colder than Cambridges.. complete idiots? I don't think so.
You have cited people, but have you just tried to compare different equipment or are you just only quoting other people?
