I paired 3A Signatures with all Audio Research gear (LS25mkII, VT-100...no slouches) and I didn't like the sound very much. I did not run the speakers full range in that configuration though, so perhaps a better balance would be achieved full range. I never listened loud, but 100 watts was more than adequate to power them for my taste. I also ran them in my home with some Classe's, Theta, and Ayre at different times. All of those amps had 100+ watts. So, I think that 80 watts should be fine to drive them to realistic levels. I used 20 watt amplifers with them once, and they were fine as long as not driven hard. Keep in mind, I had the 2wq powered subs in my system.
You may want to look into the sub, as it makes the 3A (and the amp?) sound a lot clearer and easier to drive.
