Going from B&W D3 to D4

[audio_engr]

I've upgraded 2 days ago from the 802 D2 to 802 D4. Still using the D250. I don't feel the amp has difficulties to handle the speakers. However i'm always open for any suggestions how to get the most out of my new speakers. Any idea if the upgrade to a 250 pro would be worth the investment (around €3,3K)?

802 D2 - -> D4 is sonically a BIG jump. 

Definitely would recommend upgrade to 250 Pro.

I could also buy for the same amount of money another D-250 and make them a D-800. I'm wondering which option would be the best improvement (only using Roon at the moment which is installed on my NAS).
