Short answer: the Perlisten S4b on measured sound quality, the Wharfedale Aura 2 on price. The Perlisten S4b ranks #2 of 130 bookshelf speakers at $8000. The Wharfedale Aura 2 ranks #13 at $2799, $5201 cheaper.
What the Wharfedale Aura 2 offers: Three-way “mini tower” design with a 27x90mm AMT tweeter, 4” mid-range, and 6.5” midwoofer, using an unusual bottom-firing port. Nearly “ruler flat” on-axis linearity (within about 1.5dB for most of the range) apart from one specific breakup point. Exceptional output capability with very low distortion even at high volume - the reviewer reached about 100dB average at 10 feet with no audible strain, outperforming rivals like the KEF LS50 Meta in multitone distortion above 1kHz. Wide horizontal radiation of about ±70° combined with excellent imaging and pair matching - passed demanding stereo-separation test tracks with precise instrument placement. Bass reaches a genuine 40Hz in most rooms, potentially eliminating the need for a subwoofer for material that doesn’t demand extreme sub-bass. About 20dB of usable dynamic range with no compression issues at 96dB/1m. Considered by the reviewer one of the best speakers he’s tested, potentially challenging his personal all-time top five. Watch for: A breakup/peak around 13kHz can sound sharp or shrill depending on the track, the main tonal flaw noted. Minor midbase-to-midrange balance discrepancy (about 1dB), most noticeable if the speaker sits more than about 2 feet from the rear wall. Vertical listening window is narrower than typical, a consequence of the AMT ribbon tweeter’s tall physical size - staying within about ±15-20° of the tweeter reference axis (or slightly below it) is important. Impedance dips to about 3.1 ohms with a 1.4-ohm minimum EPDR, meaning a dedicated amplifier is recommended over an AVR due to potential power-supply strain. Distortion rises at the very lowest frequencies (an expected limitation of a 6.5” woofer), and the woofer audibly struggles with extreme 30-35Hz content at high volume. Horizontal directivity narrows from about ±70° to ±50° above roughly 6-7kHz as the ribbon tweeter’s pattern collapses inward.
What the Perlisten S4b offers: Reference-grade directivity and output from a compact sealed monitor. Erin called its radiation behavior the smoothest he had measured: Perlisten’s DPC array (beryllium tweeter between two midrange domes) shapes vertical output while transitioning cleanly to the 7-inch woofer. Harmonic distortion remains below 1% at 86dB and, above 100Hz, also below 1% at 96dB; compression is exceptionally low. The response is highly linear, the midrange was a listening highlight, and the sealed F10 of 40Hz provides a predictable slope for subwoofer integration. 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. Its 78Hz F3 means a subwoofer is effectively mandatory for full-range listening despite the 40Hz F10. A roughly +3dB feature around 10kHz appears on-axis, though Erin did not find it objectionable. Price is extreme for a stand-mount and the tightly managed vertical radiation makes correct stand height important.
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.
