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 Perlisten S5m ranks #31, rated 4.4/5, and costs $15,990, which makes this an easy call rather than a real tradeoff.
What the KEF Q Concerto Meta does well: Really good in-room neutrality with consistent horizontal directivity from seat to seat. The tradeoff: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment.
What the Perlisten S5m does well: An on-axis deviation of just 0.156dB, tighter than most standmounts, from the same beryllium-tweeter DPC-Array and THX Dominus certification as Perlisten’s S7t flagship. The catch: Listening-window smoothness (0.655) and sound-power smoothness (0.503) are middling for the price, with a bass-alignment Q of 2.0 pointing to a moderately resonant low-end rolloff, and at $15990/pair it’s priced closer to a flagship tower than a typical bookshelf speaker.
Buy the KEF Q Concerto Meta. It is rated higher for sound quality than the Perlisten S5m and costs less, so only choose the other one for a particular feature it does better.

The Two Speakers In Full
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.

Perlisten S5m: $15,990 per pair The Music Room eBay
Pros: An on-axis deviation of just 0.156dB, tighter than most standmounts, from the same beryllium-tweeter DPC-Array and THX Dominus certification as Perlisten’s S7t flagship. Both StereoNET and Stereo Magazine praised its bass precision and dynamics as unusual for a monitor this size, and its on-axis response is close to tonally neutral (a mild -0.05dB per octave tilt).
Cons: Listening-window smoothness (0.655) and sound-power smoothness (0.503) are middling for the price, with a bass-alignment Q of 2.0 pointing to a moderately resonant low-end rolloff, and at $15990/pair it’s priced closer to a flagship tower than a typical bookshelf speaker.
