So much goes into sound reproduction that just speakers alone are not the answer. I understand your connection with the Sonus. I heard them with an all Krell system and they sounded excellent. You have to understand what you want for sound and only you can know what that is. Old speakers have a warm and connection to me but lack in other areas. The Daedalus are excellent speakers, I heard them at a local Audiogonners house a few years back. They sounded very nice. I also brought along a preamp that I built and to me the system sounded even better to my ears. My point being you probably would have been happy with the system and more happy once the other preamp was placed in the system. So you have to know what you want your sound to be because each part of the system is a compromise.
Happy Listening.
