Short answer: the Perlisten R5m. It ranks #42 of 222 bookshelf speakers by sound quality, rated 4.3/5, at $6,590. The Harbeth M30.3 XD2 ranks #196, rated 2.8/5, at $6,290, $300 cheaper, not enough of a saving to outweigh the sound-quality gap.
What the Harbeth M30.3 XD2 does well: A handmade English stand mount with an 8 inch mid bass, an easy load for modest amplifiers and five real wood veneers. The catch: No independent measurements have been published for this version, so its linearity, directivity and real bass extension are unknown.
The Perlisten R5m is the better-sounding choice. A large three way bookshelf speaker with dual 6.5 inch woofers, consistent dispersion, and fuller bass than most standmounts. The catch: On-axis deviation of 0.264dB and sound-power smoothness of 0.511 are middling, with a fairly pronounced -0.29dB per octave downward tonal tilt and a bass-alignment Q of 2.40 pointing to a somewhat resonant low end.
Buy the Perlisten R5m. It is rated higher for sound quality, and the $300 you would save on the Harbeth M30.3 XD2 does not close the gap.
About the ratings: the Harbeth M30.3 XD2’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 2.4 to 3.2, so this verdict could change once it is measured.
