15K system building

 I have been avidly reading TAS and Stereophile for 2 years now. I live in Rapid City SD and the local stereo store offers solid state only, with Paradigm and Definitive Tech and Klipsch as speaker lines. I am looking to build a 2 channel system in my living room which is about            20  X  15 feet in size with hardwood floors ( a hard acoustic environment). I am leaning toward a more sensitive speaker that can be driven by a roughly 10 to 60 watt tube amplifier or integrated amplifier. I am looking to spend around $12,500 - 15,000 on a 2 channel system, holding off on  analog at this time. I am after a very musical system that offers balance, transparency, and excitement with no listener fatigue. I don't want a speaker that needs to be 3 or more feet from the rear wall, so planars/ electrostatics are out. I listen to mostly acoustic, jazz, small scale classical, some techno. I am worried about too much bass in this room, and am looking to keep the bass extension down to around 40 Hz. Have thought about Totem The One, Sonus Faber Liuto( new Concerto Domus), Verity Finn, and Devore Fidelity Gibbon Super 8's or the Nines. I am okay with the warm side of neutral but want to avoid syrupy... and suspect the Liuto ( if it is like the Concerto Domus) may in combination with a tube amp be just that. Any thoughts on what speaker may be best suited for this environment and my musical tastes? Has anyone heard the new Liuto line or the new Verity "Finn"?  Has anyone tried a Prima Luna tube amp or integrated with Devore?
