If you like the Thiels then go with them as there isnt a lot out there that sounds similar . Listen for midrange/ treble hardness as Thiels not sourced just right can be fatiguing. also they are not kind to soso recordings and compression and classic rock is generally not recorded well.
Totem speakers sound a little like Thiel for extension but are more colorful and forgiving. The Forest or Mani 2 might work here. Hawks are some of the best jazz speakers around but a little small for rock
If the above is just too bright check out some Vienna acoustics baby Beethoven grand or larger. They are fantastic on classic rock and are very forgiving of recordings .
All the above need power but your amp should work well
