Short answer: the KEF R3 Meta. It ranks #10 of 131 bookshelf speakers by sound quality, rated 4.6/5, at $2,499.99; the PS Audio Aspen FR5 ranks #71, rated 3.7/5, and costs $3,499, which makes this an easy call rather than a real tradeoff.
What the KEF R3 Meta does well: 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. The catch: 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.
The case for the PS Audio Aspen FR5: Deep-reaching compact design combining a 6.5-inch woofer, rear passive radiator and planar-magnetic tweeter. Watch for: Very low measured sensitivity near 81.6dB means it needs capable amplification despite its benign 5.6-ohm minimum.
Buy the KEF R3 Meta. It is rated higher for sound quality than the PS Audio Aspen FR5 and costs less, which makes it the one to get unless you need something the other one does better.

Pros: 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 $2500/pair, called the best value in its class with near-reference-level anechoic performance. Measured bass extension of 76Hz (-3dB), with a measured sensitivity of 85.9dB.
Cons: 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.

PS Audio Aspen FR5: $3,499 per pair PS Audio eBay
Pros: Deep-reaching compact design combining a 6.5-inch woofer, rear passive radiator and planar-magnetic tweeter. Erin’s data estimates 34Hz extension, a near-neutral +0.10dB/octave slope and a 6.26 preference score with a subwoofer. Measured bass extension of 56.4Hz (-3dB), with a measured sensitivity of 83.5dB.
Cons: Very low measured sensitivity near 81.6dB means it needs capable amplification despite its benign 5.6-ohm minimum. On-axis smoothness (0.217), directivity consistency (3.46) and predicted in-room smoothness (0.229) are respectable rather than exceptional at this price.
