Short answer: the KEF R3 Meta for better sound quality, the Sonus Faber Lumina II for the lower price. The KEF R3 Meta ranks #10 of 122 bookshelf speakers at $2499.99. The Sonus Faber Lumina II ranks #87 at $1600, $899.99 cheaper.
What the Sonus Faber Lumina II offers: Handmade in Italy with a gloss-finished front baffle and black leather-wrapped cabinet - genuinely nice-looking speaker with real brand cachet. Bass extension is competitive for the size, reaching about 50 Hz in-room with mild compression and good distortion figures, so higher output levels and greater listening distances aren’t a problem down to that point. About 20 dB of dynamic range at typical listening levels (73 dB at 4m), which comfortably covers most music without the tonal balance shifting as instruments and vocals peak. Off-axis behavior is consistent - toeing the speakers 20-30 degrees out doesn’t meaningfully change the in-room high-frequency character, so placement flexibility is good once you’ve dialed in the tonal balance. Watch for: Not a neutral speaker - has a persistent high-frequency boost/lift that makes it sound forward and bright, present whether pointed directly at the listener or toed out. A slightly nasal quality traced to a resonance around 1 kHz that EQ can address. The reviewer needed to trim treble by about 4 dB on his preamp to get the tonal balance he wanted, meaning most listeners will want equalization available to fully enjoy this speaker. At roughly the same $1,000ish price point, alternatives like the Ascend Acoustics Sierra 1 V2 measure more linear (with a tradeoff in distortion and crossover-region directivity), and the Dynaudio Emit 20 offers deeper bass extension and lower compression at the cost of a more deliberately colored tonal signature.
What the KEF R3 Meta offers: Three-way design with an unconventional concentric layout: the 1” tweeter is recessed into the throat of the 5.25” midrange driver, deeper integration than a standard coaxial arrangement. A quasi sealed/ported bass alignment gives an extended low-end shelf tuned to match typical in-room gain, reaching about 50Hz for most content - deeper than recently-tested rivals like the Focal Aria 906, Polk R200, and an 8” Aperion design. Spinorama measurements show class-leading directivity and sound power, plus very linear on-axis response (at the recommended 10° toe-out) and early-reflections directivity, so it takes EQ exceptionally well. The vertical sweet spot extends to about ±20-30° off the reference axis with nearly identical tonality, unusually wide for a two- or three-way design. A clear upgrade over the earlier, non-Meta R3, eliminating the treble brightness the original had even when toed off-axis. Outperforms similarly-priced rivals (Revel M106, Wharfedale Linton, Philharmonic BMR V2, JBL HDI 1600) specifically on directivity and linearity in the reviewer’s measurements. At $2,200/pair, called the best value in its class with near-reference-level anechoic performance. Watch for: Pointed straight on-axis, there’s a 1-2dB bump around 9kHz that stays consistent across angles thanks to the constant-directivity waveguide - only toeing the speaker out about 10° tames it. Minimum impedance dips to about 3.2 ohms nominal (EPDR as low as 1.9 ohms), so it needs a 4-ohm-stable amplifier; a standard AVR likely won’t cut it. Distortion crosses the reviewer’s 3% threshold around 80Hz at 96dB output and shows added deviation again near 50Hz, indicating it runs out of headroom at higher volumes - a subwoofer is recommended for loud listening. Horizontal radiation narrows from about ±70° at low frequency to ±40° at high frequency. Below about 100Hz, compression testing shows fairly wide deviations at both 86dB and 96dB output, though the reviewer notes this is typical for speakers in this size and price class. Current R3 owners who are already happy with that speaker have little reason to upgrade.
