I just upgraded from Amati Tradition to Lilium myself and the difference is substantial. To start with, when it comes to the low end side of things there is no comparison, Lilium crushes it with no subwoofer in a moderate to large room required! I've read reviews that stated the Lilium' s mid-bass is flat and I could not disagree more. The tweeter was brighter than expected OOB, though it relaxes (though not too much) after 100+ hours of break in and now is right at home. I will say that they love to be toed in (your ears will say "when") and need to be at least 6' or more apart. Now that I've had them for a bit they have really come into their own. Dynamic with a robust soundstage, they provide significant detail without being analytical or fatiguing I know because I listened for about 5 hours last weekend and was disappointed that I had to leave the room. They do crave power and current, so don't be bashful on the power side of things. I will say though it may not be my first choice for these speakers, my ARC REF160S is at ease with the Lilium, and provides all the breadth and depth you would and should expect from these speakers. Oh, have you seen these gorgeous speakers in person? The wife acceptance factor is through the roof! My listening room is separated from my house by 8' doors with glass inserts. My wife is ambivalent about everything in my sonic sanctuary (fair to say our decorative ideas differ) but she LOVES my red wood, high polished, lyre shaped speakers. She even stops in to listen with me once in a while! If you can afford these babies and dig the sweet Sonus Faber sound I say go for it. The footprint is very similar to the Amati Tradition and your wife won't make you sleep in the room with them!
