Well I can only suggest what I have and hear. I can tell you that I have Ascend 340's across the front the CBM 170's as surrounds and a Pair of Klipsch RW-12d subs and when listening to Pandora or watching a movie I can easily have the volume at reference level and I have not heard anything bad come from my speakers. For the 170's I have the Sanus SF34B1 stands that were 129.99.
