How do Dunlavys compared to new stuff?

I also own the SC4s, and have from almost the time they originally appeared. One significant improvement to mine occured when I freed the internal driver wires from those nasty clips, cut off the splayed ends, tightly wound the newly bared ends and soldered them to the drivers where the clips had previously resided. This resulted in a smoother and more musical/relaxed sound in the treble range(YMMV). Otherwise, I concur with those who cite the flexibility in tailoring the sound of their Dunlavys with different associated equipment. For example, changing the tubes alone in my Air Tight ATM-3 monoblock amps made a very considerable difference in regard to projecting a soundstage of impressive breadth as well as imparting a greater sense of fullness to instrumental voices. I've had very few if any misgivings about the Dunlavys.
