Short answer: the Klipsch RP-600M II. It ranks #124 of 223 bookshelf speakers by sound quality, rated 3.7/5, at $449.99. The Triangle Borea BR03 ranks #199, rated 2.8/5, at $381.77, $68.22 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Klipsch RP-600M II is the more accurate choice. Bookshelf speakers with a large horn tweeter, wide soundstage, high efficiency and bi-amp ready terminals. Its measured preference score, a predictor of how neutral it sounds, is 5.64 against 4.03 for the Triangle Borea BR03. Watch for: 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 Triangle Borea BR03 is the deeper-bass choice. A budget French bookshelf speaker with dual front ports, decent bass for the price and solid, well braced build quality. Its bass reaches about 57Hz before falling 3dB, against 70Hz for the Klipsch RP-600M II. Watch for: A noticeable mid-range suckout, most pronounced in the upper mid-range/lower treble, that the reviewer attributes to cabinet resonances and driver breakup rather than a deliberate voicing choice: it makes vocals and instruments sound recessed and thin rather than warm.
Buy the Klipsch RP-600M II. It is rated higher for sound quality, and saving $68.22 with the Triangle Borea BR03 does not make up for the sound-quality gap.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared.
