Hi,
I am new to this site but have been keen on Hifi for a great many years. I have just retired my much loved T185Dorset loudspeakers-long overdue you might well argue. I chose Bowers and Wilkins CM9 's as replacements and have had them for nearly 3 weeks now. All was well for 2 weeks until I tried playing some piano music. I noticed a very unpleasant buzz/resonance coming from the tweeters in both channels. It coincided with the moment that a piano note was struck from about an octave above middle C upwards. It lasts for the duration of the attack part of the envelope and removes any pleasure one might derive from listening to music of this kind. I have tried many different Cd's and swapped amplifiers, CD players etc. I even went back to the shop and listened to the pair they had set up in their demo room. The amp/cd were far superior to mine, but through CM9's, still that horrible rasping buzz. Even my wife can hear it as could one of the assistants in the shop so I am convinced that it is inherent in the speaker design. In all other respects they sound great. Has anyone else experienced this or am I just a rivet counter?
I hesitate to criticise the Gods of B and W who are it seems, held in universally high regard but I never had this problem with my Tannoys or indeed any other set up in the last 35 years. Advice would be much appreciated
