I am amazed every time I turn on the system, the music comes out fluid, the entire wall behind the speakers seems not to be there, and the speakers they look like knick-knacks but despite this they allow me to recognize every single instrument placed in the space in front of me and the holographic image that comes out of it is amazing.The chain has many years behind it it has only been necessary to do more fine tuning over time.The few passionate people who have had the opportunity to listen were pleasantly surprised, they are honest people in their opinions.
