Sorry to say you put yourself in a bit of a bind buying speakers with only 88dB sensitivity. Because of this you either listen at low to moderate volume or else you need at least a hundred watts. If you can trade off low to moderate volume for superb sound quality there are several good integrated tube amps, the best of which is the Raven Nighthawk. https://www.ravenaudio.com/product/nighthawk-mk3-tube-amplifier/ With this you will have awesome sound, 3D, liquid, detailed and extended yet sweet, exactly what you are talking about, everything except the ability to play loud.
To play loud you are going to be stuck with high power solid state, and all the edgy bright fatiguing sound that you don’t want. But that is what you get from SS, at least from 100+ watt amps at this price point.
