Short answer: the KEF LSX II LT. It ranks #35 of 100 powered bookshelf speakers by sound quality, rated 4.0/5, at $699.99. The Palmer STUDIMON 5 ranks #66, rated 3.6/5, at $350, $349.99 cheaper, a saving that is not big enough to make up the sound-quality gap.
The KEF LSX II LT is the more accurate pick. The coincident driver provides useful consistency across listening positions, and the app offers placement and subwoofer adjustments. Its measured preference score, a predictor of how neutral it sounds, is 4.81 against 3.48 for the Palmer STUDIMON 5. The tradeoff: The 3.4dB midrange response span and treble-region dips keep it below more neutral monitors.
The case for the Palmer STUDIMON 5: The available third-party measurements predict 3.48 standalone and 6.37 with an ideal subwoofer. The tradeoff: The trace spans 4.0dB from 300Hz to 5kHz and estimates -3dB bass around 80Hz, with local irregularities despite the level overall trend.
Buy the KEF LSX II LT. It is rated higher for sound quality, and the $349.99 you would save on the Palmer STUDIMON 5 does not close the gap.

KEF LSX II LT: $699.99 per pair Amazon eBay
Same family: the KEF LSX II (larger bookshelf, estimated 4.1/5), the KEF LS50 Wireless II (larger bookshelf, ranked higher, rated 4.3/5) and the KEF LS60 (floorstanding, rated 4.8/5).
Pros: The coincident driver provides useful consistency across listening positions, and the app offers placement and subwoofer adjustments. Erin’s measurements give preference scores of 4.81 standalone and 7.03 with an ideal subwoofer, with -3dB bass around 56Hz. HDMI and USB connectivity make it convenient for a small TV or desktop system. Horizontal and vertical dispersion both reach about ±60°, giving a broad sweet spot for more than one seat. Measured bass extension of 55Hz (-3dB), with a measured sensitivity of 84dB.
Cons: The 3.4dB midrange response span and treble-region dips keep it below more neutral monitors. The existing review finds bass compression around 88-92dB/1m and rising distortion at higher levels, so the small drivers suit close listening rather than a large room. This LT version has no analog input; a turntable cannot plug straight into it.

Palmer STUDIMON 5: $350 per pair Thomann eBay
Pros: The available third-party measurements predict 3.48 standalone and 6.37 with an ideal subwoofer. Balanced inputs and a conventional compact monitor cabinet make it straightforward to use with studio equipment. The broad response trend is approximately level rather than strongly bright or dark.
Cons: The trace spans 4.0dB from 300Hz to 5kHz and estimates -3dB bass around 80Hz, with local irregularities despite the level overall trend. There are no room-EQ controls to address broad placement errors, and the available score does not establish clean output.
