In terms of resale value, sure. Deciding whether or not you want to sit with them in a long term commitment however, that's something only you can decide.
In this current climate is better to go with pro speakers and looks for speakers made from wood and not break the bank. Also to build your own speaker is quite easy today and the material is a little expensive but you can make it so much better for a few thousand on a custom speaker is nearly better than a 20000 speaker just saying also diminishing returns is a real thing
the monitor audio platinum 200 and 300 Gen 2 and gen 3 are much better than anything B&W makes, much more natural sounding and way more three-dimensional.
I auditioned the new D4 (803/804) powered by Classe Audio and I didn’t like either of them but it could be the amplifications and the speakers were merely broken-in (I used to own N802 and love it!)
IMHO you may want to consider upgrading the NAD amp which should give you much better sounding than going from N804 to 804D4
