to make them sing properly. I am driving mine with an ARC D-250 (250 w/c) tube power amp with a lot of power to spare. If you want to passively bi-amp them make sure that the two power amps that you are using have their own attenuation so that you can match the gain between the panels and the sub-woofer properly and seamlessly.I have tried the passive bi-amping route with them a while back using the Hafler P-500 (500 w/c) on the bottom end and the ARC D-250 driving the panels. The sound was fast together with excellent dynamics to say the least. However, the sound on the bottom was a little dry for my taste as the bloom on the midbass was missing. Therefore, I went back to my old configuration using only the ARC D-250 driving them.
BTW, if you can find a vintage Sansui BA 5000 power amp is a good match with them as well. I have auditioned it about a couple of months ago. The sound was almost as good as my ARC D-250 in the midrange coupled with an excellent pitch definition on the bottom end much better than the Krell KSA 250 that I have tried a while back.
