I have the Onkyo A-9155 now for two weeks and only the aural impression of "music lovers Nobby" confirm here: one is literally spoiled with a very clear and balanced audio performance, especially if you, like me, is in jazz and classical music. Since there is a good illustration of the entire sound spectrum on both the heights, as well as in the basses. Both of these supplies Onkyo amplifier optimally and by increasing the bass and treble in the loudness circuit of this hearing impression is again reinforced. The bass sound more full and the highs even clearer by this function. So I can not confirm the opinion that the loudness function is said to have only minor sound effects. However, anyone who stands on hard standing in the foreground techno basses who should buy another amplifier. The A-9155 is especially an amplifier for demanding music and the balance control is not missing either; I have hardly used my old system.
So Conclusion: The purchase was worth it for me. I am more than satisfied and would recommend this amp very.
