Bobbob, I have heard a pair of Eidolons being driven by the BEL 1001's, Spectral 360's, and the Classe CAM 350's at my dealer. Of the three, the Spectrals were probably the best, with the BEL's running a close second. However, the CAM 350's sounded very smooth, with lots of power, as well. That being said, the BEL's have plenty of power for the Eidolons, unless your listening room is huge. My dealer's listening room is about 15 x 22, and the BEL's never lacked for power in comparison to the other amps in that listening room. As the Eidolons are not very inefficient at 87 dB and can handle power between 50 to 500 watts, the BEL's power rating should not be of concern, particularly as the BEL's are known for being excellent at driving difficult loads. However, without knowing something about your room size, room treatments, associated equipment, and tastes in music, it is difficult to determine why you seem to feel the BEL's may lack power with the Eidolons.
