I haven't heard the XLs yet, but I do own a pair of the 25th Anniversary Sapphires and I've heard a number of Maggies over the years including the 1.6. I've read a number of comparisons between the XL and the 25th and I've yet to hear anyone say that the XL wasn't clearly better in many regards. The Maggies give a great sense of size, and properly set up I like the presentation. The biggest problems for me with Maggies is that setup is so very critical and they just dominate the room. When they aren't placed well, they don't sound very good. Even compared to Maggies placed perfectly, I think my 25th Sapphires do better with image placement, and better with resolving detail. I'd look for the XLs to do even better. I'd say take advantage of ACIs money back warranty and give the XLs a good play. Bet you keep them, but if you don't you're only out return shipping. And be sure to give us the complete writeup!
