The best speaker you ever heard?

Schubert: Thanks for the advice, usually I will stay away from the speakers when crank volume to some extreme level, haha just to feel the awesome sonic energy. I think there are really a lot speakers that got extreme low distortions, unfortunately comes at high price, space, and complicated setup. I'm still looking for a pair of small and compact near full range bookshelf speakers...journey started all over again...

I'm a super music lover, although I love all kinds of music no matter what it is, I can only afford a pair of Wharfedale Denton 80th Anniversary Limited Edition in walnut color and gorgeous retro look, the cabinet, the grill, and the bookshelf size just matter to me very much, and the sound definitely enough musical for me, though certainly it has limitations like dynamic and cannot go extreme loud without distortions, but it relieve me with less fatigue laid back sound. In near future, I'll look for near to full range bookshelf speakers, still I prefer something small and sound elegantly, my ultimate aim is to hear no distortions when volume reach the level my ears cannot take it, that's the next limit I need to aim for.

By the way, anybody own the Wharfedale Airdale Classic Heritage? Any thoughs on how it sound like? I think my ultimate dream is to own a pair of those, sitting in my room and accompany me till the end of my life!

Perhaps the title should change to what music do you listen to and what's the best forgiving speakers to cover almost all your music genre, this is more worthwhile to be put into discussion.
