I do not know how the Buchardt sounds, though they seem to be pretty well-regarded.
$5000 is no chump change and can get you a really good sounding setup. I am in the same boat as you having young children and are confined to desktop hifi setup. But I managed to build a really nice Cabasse Riga desktop setup that is perfect for near field listening and is easily as good sounding as Borresen. But that is out of your price range. What you could consider is a pair of Pearl Akoya. It would cost you $4000 a pair. Or a smaller Pearl Keshi set if your desk is not big.
Another good option you can consider is getting a decent 'just add speaker' integrated amplifier and then get a pair of passive bookshelves. Some examples in the range of $1500-2500 are Cabasse Abyss, Nad C3050LE, JBL SA550. Then $2000-3000 for the speakers.
Some suggestions. Triangle Comete 40th Anniversary, Dali Menuet SE, Kef LS50 Meta, Jern 12WS, Sonus Faber Sonetto II.
