Is it time in your hobby to build a speaker kit?

Good choice @N80! The stand mounted version, or the floor stander? Both are made with the same parts, just a different enclosure (plans for both monitor and transmission-line enclosures are provided with the kit). Great Neo 3 pdr tweeter, Danny Richie-designed and custom-made woofer/midrange driver, and audiophile quality x/o parts (caps, resistors, etc).

Danny is well known in the loudspeaker industry, doing x/o consulting work for other companies. He also offers mods for mass-market speakers built to a price point (and therefore compromised), such as the Elac's. His mods "correct" some engineering choices with which he disagrees.

@n80, GR Research sounds perfect for you. Danny Richie supplies the drivers, x/o parts, enclosure damping material, connectors, hardware, etc. He leaves the enclosure to the customer, providing he or she (yeah sure ;-) the internal cu.ft. volume required for the speaker design you order.

As you are content with your speakers (for now ;-), take a look at his subwoofer designs. He developed them in partnership with Brian Ding of Rythmik Audio, and they are something special. Sealed and OB/Dipole, both with Rythmik’s Servo-Feedback circuitry, and Danny’s paper-cone version of the Rythmik 12" aluminum cone-woofer. He provides the plans for his 2 cu.ft. enclosure design for the woofer, both a normal sealed version, and one with double walls, the space between them intended to be filled with sand, for damping of the enclosure walls. Advanced subwoofers designed not for home-theater use, but for music.
