Short answer: the Perlisten S4b on measured sound quality, the Wharfedale Aura 2 on price. The Perlisten S4b ranks #2 of 222 bookshelf speakers, rated 4.8/5, at $8,000. The Wharfedale Aura 2 ranks #13, rated 4.6/5, at $2,799, $5,201 cheaper.
The Wharfedale Aura 2 is the more accurate, deeper-bass choice. A mini tower style bookshelf speaker with nearly flat response, huge clean output, wide sound, and bass that reaches deep in most rooms. Its measured preference score, a predictor of how neutral it sounds, is 6.03 against 5.35 for the Perlisten S4b. Its bass reaches about 56Hz before falling 3dB, against 78Hz for the Perlisten S4b. The tradeoff: A breakup/peak around 13kHz can sound sharp or shrill depending on the track, the main tonal flaw noted.
What the Perlisten S4b does well: A compact sealed bookshelf speaker with reference grade accuracy, exceptionally smooth dispersion, and very low distortion at high volume. Watch for: 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 Wharfedale Aura 2 if the price matters more than sound quality. Buy the Perlisten S4b if sound quality matters more than the price.
