What is the efficiency of these speakers? I ask because my Spatial Audio X3s were supposedly 96 db and had a built in sub amp. At the time I had in house a Decware Torii II (around 20 wpc) and it could not drive the X3s sufficiently. On paper it was a perfect match, in reality, not so much.
I have a 300B amp from Aric Audio that I absolutely love, but I've got a feeling it would not work on the Caladans.
