I have been a B&W owner since the 1980's and I since fallen in love with the sound of the decoupled tweeters as used in the newer 700 and 800 Series monitors. Since I am now almost 65 years old and my tinnitus is at about 9kHz did I miss the boat on the acoustic properties that the 700 & 800 Series Monitors project? Does anybody have any experience with the difference between the Diamond and non- Diamond tweeters? Thanks for any serious input that you can give me... Keep Listening
