imo, your adcom amp does not do justice to your mani's. i use all classe gear with my mani's. i use the ca-200 amp. my plan is to purchase another ca-200 and run them in mono mode (700 watts each). the 200's have enough power and i love the sound of the classe amps. i took my mani's to my local mcintosh dealer and hooked them up to the 1000 watt mono's. the mani's came to life. i can live happily using 200 watts, but i know they can use quite a bit more to drive that double woofer.
