I feel that there are at least 2 speaker brands which prove you can have really good imaging and a really wide sweet spot, given a wide enough room.¿Que?
Revel and Magico.
Don't these two brands prove that great imaging in the center and very good off axis listening is not mutually exclusive??
We must have divergent views on what constitutes imaging. Magico S7 give a very wide & expansive presentation. However, they lack focus and create their own 'space'. Nebulous and homogenized is how I hear them.
Of course, it is possible that everything else in the $400,000 system was at fault.
