Short answer: the KEF Q Concerto Meta. It ranks #11 of 131 bookshelf speakers by sound quality, rated 4.6/5, at $1,399.99; the PS Audio Aspen FR5 ranks #71, rated 3.7/5, and costs $3,499, so there is little reason to consider the other one.
What the KEF Q Concerto Meta does well: Really good in-room neutrality with consistent horizontal directivity from seat to seat. Watch for: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment.
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. The catch: Very low measured sensitivity near 81.6dB means it needs capable amplification despite its benign 5.6-ohm minimum.
Buy the KEF Q Concerto Meta. It is rated higher for sound quality than the PS Audio Aspen FR5 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

KEF Q Concerto Meta: $1,399.99 per pair Amazon Crutchfield eBay
Pros: Really good in-room neutrality with consistent horizontal directivity from seat to seat. Directivity holds remarkably steady from lower treble into upper treble, where many similarly-priced speakers narrow sharply as frequency rises: one of the reviewer’s top 10 picks under $1,500. Measured bass extension of 53Hz (-3dB), with a measured sensitivity of 84.2dB.
Cons: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment. Needs to be pointed closer to on-axis rather than heavily toed out: combined with its rolled-off, shelved-down top end, too much toe-out makes it sound noticeably dark.

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.
