Small monitors/bookshelves for classical music


I currently own KEF iQ5 floorstanding speakers and ROTEL RB980BX Power Amp. I listen to classical music(Bach, Mahler, Wagner, etc). Though KEF iQ5 lacks deep bass, I am completely fine with that when listening to classical music.

I am seeking to buy a pair of new/used monitors/bookshelf speakers. I want a truly "bookshelf" speaker which can be put on a desk or even a bookshelf. I will not put them on stands. Neither will I pair them with a subwoofer. But I will pair them with this ROTEL RB980BX. ROTEL RB980BX is very powerful, 120W/ch. I can spend below $600.

After doing multiple painful searches online and on this forum, I have several potential speakers/monitors in mind.
PSB Alpha B1
B&W 686 or 685
Paradigm Mini

Try looking ay Tekton Design. They have just what you need at a price that is sane.
Highly reviewed also.
You have a good short list so far. No substitute to going and have a listen with your own ears! Let us know what you decide.
I am using the Von Schweikert VR-1s and love classical and small jazz group music through them. I did add a small REL sub but it really only matters with rock and new Jazz music. They can often be found at $600. And, mine are not for sale.
