Short answer: the Philharmonic BMR Monitor for better sound quality, the Triangle Borea BR03 for the lower price. The Philharmonic BMR (v1) ranks higher than the Triangle Borea BR03 (#40 vs #198 of 222 bookshelf speakers) but is discontinued. Its replacement, the Philharmonic BMR Monitor, is rated 3.6/5 at $2,200; the Triangle Borea BR03 is rated 2.8/5 at $399, $1,801 cheaper.
What the Triangle Borea BR03 does well: A budget French bookshelf speaker with dual front ports, decent bass for the price and solid, well braced build quality. 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.
The Philharmonic BMR (v1) is the more accurate pick. A large three way bookshelf speaker with a ribbon tweeter, flat response, broad coverage, and an unusually expansive midrange. Its measured preference score, a predictor of how neutral it sounds, is 4.86 against 4.03 for the Triangle Borea BR03. The tradeoff: The measured 83dB sensitivity and roughly 4-ohm load demand meaningful external amplification.
Buy the Triangle Borea BR03 if price matters most. For better sound quality, the Philharmonic BMR Monitor, the replacement for the discontinued Philharmonic BMR (v1), is rated higher but costs $2,200.
