will putting SDAT: MS-E800's at 4 ohms on my marantz 1030 which is only powering 8 ohms speakers at the moment hurt it? also if they will not hurt it will they sound worse than the 8 ohm speakers
Run them at 8 ohms, make sure to let your amp breath and definately DON'T over power the base, keep the base flat. The dynamics will be very impressive.
