I like are clarity, airyness, warmth.
You're not going to find warmth in the D3/D4 and even maybe D1/D2. B&W's changed from warm to neutral to bright. Those conditions can better be found in the 800N, 700S. The differences between the N-D4 is mostly the high frequency and bass extension. The old models are still excellent choices aside from wear and tear. If you want something newer, try a different brand.
