i've owned the solos and still own the studios. the solos are a great speaker, but have a certain attribute, which is they're power hungry and really open up at higher volumes--they're not really optimal for polite, low-level listening. i agree with the general consensus--changing your interconnects won't make an audible difference. changing your preamp or power amp will alter things, but probably won't change the fundamental character of the speakers. if you want to hear a significant difference, you'd probably need to change speakers. (i haven't heard the aads, but would conjecture that they share much of the signature of the solos, so i'd look at something else).
