In his review of the Phonitor2, Axel Ritt asks a very good question:
"Seldom is a topic so controversially debated over decades like mixing without the appropriate monitors. Why?"
After extensive testing, his verdict on the Phonitor Matrix is clear:
"Unnatural listening on headphones with the center in the head can be in fact adjusted and processed individually to a great extent with the product's Matrix, making it possible "for the first time" to mix with headphones. As soon as you "understand" how the parameters work, you can use the Matrix to create your own personal environment."
