Dynaudio Heritage + Gold Note IS-1000 Deluxe

I’ve driven a pair of the Dynaudio Heritage (as well as Sonus Faber Maxima Amators) with both a PrimaLuna Evolution 400, and a Sugden A21SE. The latter is a lesser known British integrated. There is a YouTube video comparing it favorably to the Pass INT25. The Sugden is available for $3750 (Don Better Audio). FYI, I listen to classical, jazz, and classic rock at moderate volumes, and the volume control is around 9 o’clock. Best wishes.

I couldn’t be more pleased with my Gold Note IS-1000 Deluxe! It has an elegant, silky smooth signature. It’s paired with Totem Forest Signatures and has plenty of power to spare. The combination is sublime!

my vinyl collection contains usually idm, electronic sounds 

The Sugden does seem to be a good choice, not enough power though.

I would seriously consider the underrated Mimas. I'm using it w my Wilson SabrinaX 87dB sensitivity and love it.  It is class AB with tubes in the preamp. 280W into 4 ohms. You could even roll different tubes if want to. There is one on-sale right now below your budget, even has DAC and phono modules included. 14 days return.
