Veiled 'wet blanket' sound from tweeters


Is it my speakers or my amp?

My gear consists of B&W PM1 with Rotel Integrated RA-1570.  

I'm experiencing a lack of detail and separation from the speakers , specifically at the tweeter source.   Switching between headphones (Grado RS1) and speakers, it is like there is a heavy blanket covering the tweeters.  Midrange/bass is fine.

Switching sources between DAC/Turntable yeilds no difference.

I'm actually wondering if the crossovers have been damaged.   

I don't really have the luxury of switching components.  Any ideas on what my next steps should be?

My first guess is that you have a couple of blown tweeters.  A sometimes cause of this is an amplifier driven into clipping.
I was thinking blown tweeters too...at low volume put your ear close to tweeters...
They are bi ampable, correct? Just hook up the tweeters and listen, don't turn it up..

Remove those silly jumper bars they use and add a  pair of good copper jumper wires. Just strip the ends and use that.

One will tell you if they are blown, or a crossover problem. The second will tell you is there is a poor connection (s).

Then, WHY there is a problem...What caused the problem? Overdriven or amp oscillation (clipping)..
