I have long searched for and read a lot of testing and reviews. This system is simple bomb. Have indeed had my doubts because here negative experiences in the reviews are indeed available. Today I wonder, however, if someone was just frustrated with the rating. Materials and workmanship just Top! The subwoofer is absolutely impressive, because I've not looked bad when unpacking. Then set up and connected the whole (Denon AVR-X 2000). Then calibrated and then inserted music and then NEN film. The result was and is overwhelming. The Bass (got him now at a low level because of the neighbors ;-)) is kind of powerful and clear, is just great! The satellite with its 2 midrange and 1 tweeter are clear. The Souroundsaund is just awesome. If one looks only ne simple animal documentary you look left and right to look to where the animals are :-). For me, this purchase was the perfect decision in the jungle of 5.1 systems. Whether to the Denon AVR 2000 must be the responsibility of each X itself.
