IF you are open to NOT spending that much for bookshelf speakers I have two pair that can be had for well under $1000 that I would use on shelves if I had to.
One is my larger refurbed OHM Ls. These can be had via the OHM online store newly refurbed with modern components when available for about $500/pair. They sold for $400 a pair back in the late 70's, so adjust that for inflation for an indicator of what new speakers in the same cateory would cost today.
The other is my smaller Triangle Titus XL monitors that I bought new for about $500 in the late nineties that still sound wonderful.
