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

Here's another excellent choice for your situation and music taste. Mirage OMD5 sold by Vanns, brand new. A subwoofer could always be added later if needed.
Oops, missed your price point Hl10027, sorry.
Quad 9Ls (or 12Ls) actives are nice if you have preamp-outputs somewhere in your system.
I have both on computers & like them a lot.
The 9Ls can be found for about $500 used and are very silky and well defined at at the same time.
They can even be driven right from your source with their own remote volume control.
