Short answer: the Perlisten S4b. Both are rated 4.8/5 for sound quality (#2 and #3 of 131 bookshelf speakers), and the Perlisten S4b costs $8,000 against $9,999.98 for the KEF Reference 1 Meta, so with nothing between them on sound quality, price settles it.
The case for the Perlisten S4b: Reference-grade directivity and output from a compact sealed monitor. The tradeoff: Erin measured only 84.5dB sensitivity and an impedance minimum just under 4 ohms, a difficult efficiency/load combination that deserves substantial clean amplification.
What the KEF Reference 1 Meta does well: Meta technology places a Helmholtz-style resonator behind the tweeter to absorb rear-radiated resonance, and pair matching is within about ±0.5dB: unusually tight for a passive speaker. The catch: At roughly $10000/pair, nearly four times the cost of the similarly-sized KEF R3.
Buy the Perlisten S4b. Both are rated the same for sound quality, and it costs $1,999.98 less than the KEF Reference 1 Meta.

Perlisten S4b: $8,000 per pair Perlisten Dealer Locator eBay
Pros: Reference-grade directivity and output from a compact sealed monitor. Erin called its radiation behavior the smoothest he had measured: Perlisten’s DPC array (beryllium tweeter between two midrange domes) shapes vertical output while transitioning cleanly to the 7-inch woofer. Harmonic distortion remains below 1% at 86dB and, above 100Hz, also below 1% at 96dB; compression is exceptionally low. The response is highly linear, the midrange was a listening highlight, and the sealed F10 of 40Hz provides a predictable slope for subwoofer integration. Measured bass extension of 78Hz (-3dB), with a measured sensitivity of 84.5dB.
Cons: Erin measured only 84.5dB sensitivity and an impedance minimum just under 4 ohms, a difficult efficiency/load combination that deserves substantial clean amplification. Its 78Hz F3 means a subwoofer is effectively mandatory for full-range listening despite the 40Hz F10. A roughly +3dB feature around 10kHz appears on-axis, though Erin did not find it objectionable. Price is extreme for a stand-mount and the tightly managed vertical radiation makes correct stand height important.

KEF Reference 1 Meta: $10000 per pair KEF eBay
Pros: Meta technology places a Helmholtz-style resonator behind the tweeter to absorb rear-radiated resonance, and pair matching is within about ±0.5dB: unusually tight for a passive speaker. Sounds most neutral pointed straight on-axis rather than toed out, with no 5-8kHz harshness of the kind that plagues many speakers marketed as “detailed.” One of the most three-dimensional soundstages the reviewer has heard from a passive speaker, beaten only by $13,000+ active Xmachina Pulsar MK2 monitors (though this speaker’s tonality was preferred). Distortion stays below 1% down to about 70Hz at 86dB, and below 1% to ~150Hz / below 3% to ~70Hz even at 96dB. High-frequency response holds essentially flat as volume increases (no audible crossover or voice-coil compression) giving strong dynamic range up to its output limit (about 98dB at 3.5 meters before the woofer starts running out of excursion). All-passive design still measures ±1.5dB from 80Hz to 16kHz with zero DSP. Swappable dual-port system (long port for near-wall placement, short port for out-into-the-room placement with more bass extension) lets you tune bass behavior to where the speaker actually sits. Measured bass extension of 52Hz (-3dB), with a measured sensitivity of 82.5dB.
Cons: At roughly $10000/pair, nearly four times the cost of the similarly-sized KEF R3. Radiation narrows from about ±60° in the midrange to ±50° at high frequency: tighter than the reviewer’s ~70° preference (though wider than the R3’s ~±40°); toeing the speakers out for more width sacrifices treble energy that then needs EQ to restore. Moderate-to-low sensitivity (measured 83-84dB) calls for a solid amplifier. In-room bass only extends to about 40Hz, so a subwoofer is worth adding for bass-heavy material at higher volumes or listening beyond 3-4 meters. Minor directivity mismatch around 2kHz shows up in measurements, likely a vertical diffraction effect that wasn’t fully explained. Bass port choice (long vs. short) meaningfully changes the sound depending on placement, so the wrong port for your room can leave the bass sounding off until you experiment.
