My Alons have a sensitivity of 87 db. The 1070 can drive them and I have a powered sub. I feel using a dedicated amp with it's own power supply will be better , esp when playing signal with peaks and demands (movies).

VD, can you comment on this since you use a 970? Also, do you use the analog input with analog bass mgmt?
