This is mostly a question for Dave as I doubt anyone else has been able to directly compare the Diamond Sierra with a Sierra-2EX.
The first question is have you been able to keep possession of a pair of the Diamonds?
Have many pairs of the Diamonds been sold?
Since when the diamonds made their debut, they were compared to the S-2s, do you feel that the difference in detail noted in the Diamond reviews was a product of the EX woofer, the Diamond tweeter, or both.
After an extended period of time listening to both the Diamonds and the 2EXs, what are your impressions comparing the two?
Edit: What got me thinking about this, I was listening to AIX's Lawrence Juber DVD-A "Guitar Noir" through my full system in 5.1 all RAAL equipped glory! It is stunning how real his acoustic guitar sounds in this title, and it is equally as stunning the level of detail to be heard from the percussionist, he uses lots of metallic instruments like bells and triangles, brushes on cymbals, and a fairly diverse array of other percussion instruments.
I'm just struggling to comprehend how any of this could be improved upon! I do understand that it was reported that the diamonds showed more detail with complex passages like an orchestra, or big band style, I truly wish they weren't so prohibitively expensive that I might have the pleasure to demo a pair myself.
I also was thinking about the reference to hearing finer details Of Diana Krall's performance, but was thinking those frequencies would be more in the mid range, thus my question regarding what transducer was in fact providing the increased level of detail. I suppose the true acid test would be comparing a diamond equipped Tower pair to a ribbon equipped Tower pair, with the dedicated mids that would mitigate differences from those frequencies.
