I can comment on the 805D vs 805N & 802N - all three of which I have owned. I prefer the N tweeter and overall presentation. For whatever reason, the 805D never sounded good to me. I bought them new, played them for 4 months until I had about 350 hrs and still didn't "get" them. Switching back to my beloved 805N and now 802N, I am in heaven.
