From what you have said, I suspect that you're similar to (maybe not quite as extreme as) a player in my chess club. He's 23, self-taught, has just played his first two tournaments over the last couple of months. He's a tactical whiz, trained up at blitz and bullet online, but with absolutely zero formal study of endgames and such. He's currently rated 1853 (provisional) after those two tournaments, and is probably a little underrated still (I know he was very nervous and threw away at least one half point in the first tourney in a way that is not reflective of his "true" skill level).
He mentioned at yesterday's club meeting that he doesn't know much about endgames, so to see exactly how small his knowledge base was I set up the following position and asked if it was winning for white, or if it was drawn, and whether it mattered whose move it was:
When he said he had no idea, I started working through a few variations for him, until I reached this position and said "which is of course a simple draw":
He looked at me blankly, and I ended up teaching him the "just retreat directly away from the pawn" drawing method. It was new to him.
This might be a particularly extreme case, but he's definitely an example of a player who is maybe close to 2000 strength via tactical acumen, but has no endgame knowledge base. I would NOT advise him to go anywhere near Dvoretsky until he's worked his way through Silman first. He might even be well advised to start with the Endgame Fundamentals book that I so quickly dismissed as worth your time.
On the other hand, if someone is roughly 2000 strength, but with relatively balanced ability (endgame knowledge and tactical skill being about equivalent), then that player is probably ready for Dvoretsky (which is much more in depth, at the expense of accessibility) without bothering with anything simpler first.
