Check out the Ascend Acoustics Sierra 1. An actual bookshelf speaker that falls within your budget. Uses the same tweeter that Spendor has used in some $3K speakers.
If you’re willing to buy used, consider the Vandersteen VLRs. With a bit of patience, you should be able to pick up a lightly used pair for $1K. Someone here recently got a pair for less than $800.
Schiit Audio allegedly sources most of their parts in the U.S. Definitely consider them for amplification.
