B&W 800D vs 800 Diamond


Hi all....what is the difference between the B&W 800D and 800 Diamond speakers? Would anyone have images to show the difference? I can't seem to find a difference using google search. Could some B&W aficionados shed some light? Thanks so much!

The following reviews describe the differences:

I wondered this also just before I purchased a used pair of 802D2 so I called B&W. BTW, these guys are so nice. They research things for you like how much did things retail for then. I asked them to compare like 6 speakers. The were Johnny-on-the-spot. 
Here is what they told me. They said the D stands for diamond in all of the models that have a number then a D. They may have come out with different models of 802D but they are all diamonds. The 802d that I purchased have a chrome ring on the tweeters. B&W were able to identify them as 802 Diamond 2

 

i hole this helps. If you are unconvinced just call them. They are wonderful people

The thing I like the most about my past B&W and these are the midrange. Yes the tweeters are clear without being harsh. Yes those woofers are amazing for their size but still need a subwoofer. My friend has a 15” sub turned down low and it is amazing how it adds. 
The main thing is the midrange. If I play Chris Rhea or Robbie Robertson I can easily identify each instrument, even when they are all playing the same note. I find that sweet spot of stereo imaging is plus or minus 2.5 ft right or left. I can hear the vibrations of vocal cords, not talking about vibrado. If I listen to old music like The Stones or Rod Stewart then everything I just said can be ignored. Of course it stands to reason that in order to hear well with a good set of speaks one must start with a good source. I stream with a Cambridge. Even when songs play with 192 they do not sound as good as a CD at 44. There is a lot of variation in our hearing vs the frequency so what might sound good to one person may not sound good to another. Also, a hearing test will test a miniature set of frequencies, like 8 of them then plot a graph. My mid base area is not bad yet i like more mid base from my stereo so i tend to adjust for that in my equipment. It isn’t like the old days of just adding an equalizer. The point also is that a hearing test almost never gives you more than one frequency at a time so different people might perceive the separation of instruments differently. For me, if there is background noise I cannot hear someone speaking to me as well. This is common with aging. That is never tested for with a hearing test. U will just be told you are hearing less high frequencies. I do like that null test machine stuff. I think it is great for objectivity. I think rather than spend $750,000 on a set of speakers I would rather spend that money and get ear implants when they come out! Kidding of course
