Hi BS try it the other way round the Abrahamsen controlling the bass, will be even better than the 8005 on these duties. When "any" amp is required to do two duties its going to share its power and control between two set of drivers. You already noticed an improvement over the 8005 in normal integrated mode. That why 2 V4.0UP's in bridged mode driving a single pair of speakers each sound so much better, one set of speaker outputs driving the bass, one driving the treble sounds even better and you have lots of Watts on hand! But it all costs!
