I've just upgraded my B&W 685's to CM5's. Loving the clarity and soundstage, a massive improvement! However I've already thought my speakers were damaged about 5 times whilst listening to music...
On several tracks I've heard a crackle or clipping, sometimes through the left, sometimes through the right. I attempted to isolate the problem but could feintly here it with my old speakers. The final test was using my iPhone and P3 headphones, where the same crackle was there, just incredibly feint, almost inaudible to me.
So it seems proven that this crackle has always been there on some audio tracks, just the new speakers make it extremely obvious. I guess it's something i'll have to get over to stop having the fear everytime I hear a crackle. Unless there's any suggested ways I can dial the problem out? Currently listen to audio with my av amp using audyssey flat settings, to my ears this sounds better than the direct or pure direct setting on the Marantz SR5007.
Bottom line is, I love the new speakers and it brings life to previously dull material, football for example sounds much more 3D! But occasionally in a movie or a music track I find the crackle annoying
