The 802D2 do sound incredible, but there's always that point of diminishing returns.
Interestingly, the 802D2 appears to be the best measured B&W speakers I've seen. HTM measured +/-2.9dB on the 5-point avg. 200-10kHz FR.
I have the 802Ds and 800D2 what an improvement :)
"There's another way to look at this phenomenon. Both the 802D and 800 Diamond could play at very high levels without distress, but I found I could play the 800 at much higher levels without evoking any listener stress."
Also there is a bit more than mere measurements! Anyway to me the 800Diamonds D2 are outstanding and I would not trade them for the 802D2 but that's just me :)
To each their own, I use my ears rather than endless measurements.
If I understand you correctly the 802D2 should be king of the hills in the B&W800 series yes?
Fair enough I am not sure where you were going?
