Short answer: the Perlisten S4b. It ranks #2 of 222 bookshelf speakers by sound quality, rated 4.8/5, at $8,000. The Perlisten A3m ranks #51, rated 4.2/5, at $3,000, $5,000 cheaper, which does not close the gap in sound quality.
What the Perlisten A3m does well: A sealed high output monitor with dual 8 inch woofers and a waveguide tweeter, a great match for a subwoofer in a home theater. The tradeoff: The low-quality vendor Spinorama data measures only 85.8Hz at -3dB, 74.1Hz at -6dB, and 55.7Hz at -12dB, conflicting with Perlisten’s much deeper in-room extension claim.
The Perlisten S4b is the more accurate choice. A compact sealed bookshelf speaker with reference grade accuracy, exceptionally smooth dispersion, and very low distortion at high volume. Its measured preference score, a predictor of how neutral it sounds, is 5.35 against 4.30 for the Perlisten A3m. The catch: Erin measured only 84.5dB sensitivity and an impedance minimum just under 4 ohms, a difficult efficiency/load combination that deserves substantial clean amplification.
Buy the Perlisten S4b. It is rated higher for sound quality, and saving $5,000 with the Perlisten A3m does not make up for the sound-quality gap.
