Did I damage my speakers?


Group,
Need your expertise: I own a pair of Vienna Acoustics Beethoven Baby Grand SE's.

I recently paired them with a new-to-me set of Bel Canto REF600M monos, which replace a Bel Canto REF500S dual mono stereo amp. My preamp is a Bel Canto Pre3VB with the battery power unit.

This weekend the tweeters and upper mids, vocals (mostly female), piano,  sound hazy, at times somewhat distorted, grainy. My listening level is typically between 60-75db. I don't push these speakers hard, but I'm also getting acquainted with an amp now giving 100wpc more than I'm used to. Recently I may have pushed these speakers a bit too hard, getting up into the 80db range a few times. Could I have over-driven the tweeters with this more powerful amplifier?

I've owned the REF600M's for about two months; until this weekend, never heard this kind of distortion/congestion at the top end. Doesn't happen on everything I play (mostly CD's). Before this weekend the sound has been wonderful.

I've had these speakers for almost 7 years and have never noticed something like this before.

Wondering how to troubleshoot this.

Thanks in advance for your insight/perspective.

J

I agree with rocray I've just had a similar problem after a cartridge change on my lp12. It was great to begin with but then I noticed a very slight hiss on the right hand channel and slight distortion during loud passages I didn't think it was the brand new cartridge so I thought back to what I had done when the problem started and I had moved the phono stage, so I checked the connections, the leads are quite short, and The black cable had come loose and wasn't fully attached so I swapped it out for a pair that I wasn't using and made sure both cables were secure now the problem appears to be solved. Hope you solve your issue as easily.
