my m901 with dodd buffer and battery power supply did not get along with my dali ikon 8's.
the 8's are 6 ohm, 90-91 db sen.,had two 8" bass drivers, midrange driver and a dome/planar high frequency module. there was no bass. the m901 worked just fine with my 8 ohm ushers which are 87db. went to a 50 watt tube integrated and the bass was there.
