I had a longer post which seems to have disappeared. So my last post was too brief. To explain, I listened to Opera $10,000 speakers with a diamond tweeter, tubed amp. This was a fantastic speaker for a studio monitor. Extremely analytical and made mincemeat out of many of my favorite recordings. At the time I thought "this is great for use in a studio but not when listening to anything less than a perfect recording".
The dealer, of course, was enthusiastic about the speaker saying it was "tactile" meaning you could reach out and touch the singer, vocals were so realistic. Even better than Thiel and without the dispersion / integration problems of a ribbon tweeter so as Levinson's Rosebud of Proac Future speakers. Which was totally true IF the recording was perfect. For those of us who want to listen to their favorite music, not just "audiophile" recordings these speakers were not practical.
So forgive me for jumping the gun, I just saw diamond tweeter and assumed B&W is taking the studio monitor to the next level while leaving music lovers behind. Isn't this what diamond tweeters are famous for? B&W makes great speakers, as good as anyone. I was disappointed because, to my taste, B&W speakers are already bright and detailed enough; so I was really hoping they would choose a more realistic voicing for their speakers. It appears B&W thinks otherwise.
It was interesting to read Paul Bolin's (I think) review of the $8,200 McIntosh amps. He said something about making his head hurt trying to see how the Mac's lack of detail detracted anything from his listening enjoyment compared to Halcro's super detailed amp. So for music listening how much detail is necessary? Studio monitors are a different story, of course.
