I have done a fair amount of bi-amping, although never with Soliloquays. I have a Technics horn system which I run with a Sophia tube amp for the mid range and tweeters, and the factory solid state amp for the horn subwoofer, and find the effect pleasing. Most consultants would direct you away from this activity, simply because of the different tonal signature of the different kind of amps. Also, the power requirements of the speakers may be troublesome with the relatively low output of the Jolida. In any case, what do you have to lose by experimenting? Avante Gard has a nice discussion in their literature concerning this issue, although perhaps more appropo for horns.This kind of stuff is always fun to do. The Jolida can be rewired to bypass the controls, or you can simply turn the gain up full and use your preamp to control the output, saving the amp for other uses. I also run a pair of Klipsch LaScalas with the same Jolida in a large room to good effect.
