Suggestions for bookshelf speakers that have great dynamics, budget of $500 used.

Obviously we will see as time goes one.
At this sort of price points it is no big deal if I end up not liking and want to try something else from the excellent suggestions here.
Tbh with my Sanyo receiver with tone controls I can boost the treble a little if needed, I could not really fix the perceived harshness of the Silver’s though when pushed.
I have already found out the Haydn are more critical of placement. I had a little too much bass boom and just moving the LH speaker 3 inch forward and 4 inch further apart and narrowing the toe in cured that entirely.
Oh and they absolutely need the port bungs in place in my application and location.
I certainly am a lot more aware of top shelf monitors around this price now so that is a very good thing indeed!

uber, I found them easy to listen to and if you decide you'd like to try something else, they're easy to move.  I've tried a couple of different Monitor Audio speakers and they were too bright for me also.  Let us know how they work out over time.

Haydn are great looking speakers - since you say they are in good condition, you can resell them at the cost - good thing about getting used gears, as new ones depreciate...enjoy the hunt!

VA speakers tend to be very natural/a little forgiving (choose your epithet).  My favs are the Beethoven Baby Grand and the Liszt; I imagine these characteristics extend to most if not all models (not quite so keen on the Beethoven Concert Grands).

TBH forgiving and neutral is probably for the good.
For sure they don't have that blam in your face presentation but that can get old very quickly.
I had a Lyra Dorian cart which was very direct and in your face and at first I was thrilled with it.
But that presentation ALL THE TIME soon wore me down and it became very fatiguing.

I certainly don't want that in my speakers
