3-4 dB dip at crossover region: what should I listen for to hear it?
You don’t need a spl meter and generators, you just need to listen to a frequency sweep. Many audio test albums have those tracks.  
Borresen Loudspeakers
Don’t forget that Børresen speakers are always demoed with 150K of Ansuz cabling.   And their bass and placement is really tailored to big rooms, just like the Raidhos Michael used to design.   
can subwoofers make things worse?

Do the words  full loom, giant killer, cavernous, totally non-fatiguing, musical still appear as often as in the 1990’s?  
Recommend me a DAC under 3k
I think the question begs for a streaming function which does not leave many options. Those from Lumin and Auralic come to mind. Lumin’s software is solid a used T2 or T1 which is easier to find.   
Gustard R26 on sale
In EU you can’t beat Audiophonics prices. No reason to buy from China.

@singingg   Elliott Carter's Horn concerto on the Bridge label? Wow, you have great taste, I agree.  
IsoAcoustics GAIA II isolators on Solid Steel SS-6 Stand
The angle of those stands’ legs do not suit Gaia feet. ISO acoustic feet are all supposed to stand straight.
