Audio, no way.
I've listened to lots of speakers (dozens) over the years (I'm glad you know how many I have though) and if I go back and listen to them again, in the same set up (friends houses, dealers), they sound different from what I remember, because I only heard them briefly with just some material. It takes several listens over weeks/months (like at friends houses) to start to know how a speaker sounds. And even then, it's not your equipment and it's not, much more importantly, YOUR ROOM. That's why some speakers sound great in some rooms, and not so much in others. Some of my friends have moved their speakers around (same gear) and in different rooms they sound better or worse. I have too with my Ushers (and several other low-fi speakers I've had before that). They are great in my office, not so much in my living room.
With better ears and less of an ego (I heard that speaker, I judge it as this blah blah based off such a limited time with it--like 5 minutes lol--...no I'm right, you don't need to own a speaker yourself for weeks to know what it sounds like! pssh! such nonsense! I went to a meet! I KNOW!) you'd understand.
Duh.

Thanks Josh, but I'm mostly going to be listening at low volumes and I don't mind getting blown away by what I have now, which gets VERY loud and I have a sub too in my small room. But that's only when I rock out, which isn't that often.
So I doubt an inch more bigger woofer (and about 10hz deeper) than the 520's with the Quads is going to kill me. In fact, I'm looking for a more filled out sound, one that I can turn off my sub with without feeling I'm missing something or it sounding too thin (the 520's without a sub do).
We'll see of course, once I've had a good week or so with my room and my gear and my material if I like them or not. I bet I will. :)
