Depends on the room! I aggree with Chadnliz Vandersteen are some of the best also Magnapans. Here is my theory, using Vandersteen as a example, there are others. Vandersteens have pots and crossovers to tune each speaker to the pre amp and room acustics. Once each speaker sound the same and matches the room the sound blends together and the speakers disappear also they use a design where the speakers are usally almost supended in the enclosures to avoid directional sound. Now there are some good processors out, that sounds like a big no no. I use to think that way till I got feedback from people that used them they adjust each speakers to the room and does what vandersteen does with the little pots on the back of the speakers electronically with a microphone. This could hurt something else in the sound path or coudl really help if the speaker/rooms needs a little help intergrating.
