Tweeter Distortion

Well- that was interesting1 the uppse distortion was audible in the other speakers!
Now what?
My old CD player is over 15 years old- could it be that? But then again, it seems like it's also there with my turntable?

Well, that was interesting! The upper distortion was audible on the other speakers as well? What's strange is that I thought it might be my 15 year old CD player, but I seem to have the same problem on my turntable as well?

may be it was problem caused by cosmic energy:) These days I hear twetter distortion too on both speakers dynaudio c1 and Harbeth shl5 with diffrent amps and diffrent cd palyers:) Interesting opinion abaut rca cables

As I was reading the replies in this thread, I was thinking that the probability that the speakers are bad was going to be low. It's hard to destroy speaker drivers - you have to try hard quite with destruction on your mind. It's possible to do but not so easy.

So, it could be
* a failing speaker x-over component
* a cold solder joint in the speaker x-over
* dirty RCA contact all around + dirty speaker contacts
* failing power supply electrolytic capacitors in the power amp

There might be other potential causes but these are the ones I can think off immediately....

I'm also thinking it could be my aging Conrad Johnson PF-2 preamp?
I'll check the contacts- that's an easy start.
