B&W 805 distortion question

Seems the first step might be to post the artist/title of the CD and at what point of which track the problem occurred. If you're lucky, others will have the same CD and can check their copy.

If they notice the same issue, then you can quit worrying about your system. It's no secret that there some recordings either have mistakes in them and/or are poorly recorded.

Its easy enough to check. Unplug your speaker cables at the speakers but not at the amp. Plug them into the opposite speaker and listen to the recording again. If the problem goes to the other channel, its most likely a bad CD. If not, its probably the tweeter.

The previous troubleshooting suggestions are valid and you should do so.

I had a similar problem the other day with a hi-res Steely Dan recording - the tweeter output sounded horrible for a few seconds. At first I suspected a blown tweeter. But I know that the Gallo CDT tweeter is virtually indestructible so I did the cable swap routine. It turns out it was the recording and not my gear - whew!!

But I must admit that I was quite surprised that a Steely Dan album would have sketchy sonics, they are usually 100% *perfect*.

So, let's cross our fingers and hope that your CD is at fault and not your gear...
