Short answer: the TAD Compact Reference One (CR1TX) if sound quality matters most, the Klipsch RP-600M II if price matters most. The TAD Compact Reference One (CR1TX) ranks #1 of 222 bookshelf speakers, rated 4.9/5, at $87,500. The Klipsch RP-600M II ranks #123, rated 3.7/5, at $449.99, $87,050.01 cheaper.

Why pick the Klipsch RP-600M II: Bookshelf speakers with a large horn tweeter, wide soundstage, high efficiency and bi-amp ready terminals. The catch: On-axis, the treble runs notably hot (even hotter than the original Klipsch RP-600M in some respects) and needs about 20° of toe-out or the grille installed to sound balanced.
The TAD Compact Reference One (CR1TX) is the better-sounding choice. A superb bookshelf speaker, a large three way with a coaxial driver that keeps sound consistent around the room and incredibly low distortion. The catch: Extraordinarily expensive at $87500 per pair.
Buy the Klipsch RP-600M II when the price outweighs sound quality for you, and the TAD Compact Reference One (CR1TX) when sound quality outweighs the price instead.
