Short answer: the Wharfedale Aura 2. It ranks #13 of 131 bookshelf speakers by sound quality, rated 4.6/5, at $2,799. The Buchardt S400 MKII ranks #64, rated 3.8/5, at $2,400, $399 cheaper, not enough of a saving to outweigh the sound-quality gap.
What the Wharfedale Aura 2 does well: Three-way “mini tower” design with a 27x90mm AMT tweeter, 4” mid-range, and 6.5” midwoofer, using an unusual bottom-firing port. The tradeoff: A breakup/peak around 13kHz can sound sharp or shrill depending on the track, the main tonal flaw noted.
The case for the Buchardt S400 MKII: Two-way design with a 3/4” tweeter on a well-implemented aluminum waveguide (compression-driver style, letting the small tweeter cross unusually low at 1800Hz), a 6” SB Acoustics-style mid-woofer, and a tunable 5x8” passive radiator adjustable via rear weights. The catch: Sounds a bit bright and slightly boosted above about 7-8kHz on-axis, even with 30° of toe-out - benefits from about 1 inch of sidewall absorption at the first reflection points to tame it.
Buy the Wharfedale Aura 2. It is rated higher for sound quality, and saving $399 with the Buchardt S400 MKII does not make up for the sound-quality gap.

The Two Speakers In Full
Wharfedale Aura 2: $2799 per pair Crutchfield eBay
Pros: 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. Measured bass extension of 56Hz (-3dB), with a measured sensitivity of 87dB.
Cons: 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.

Buchardt S400 MKII: $2400 per pair Buchardt Audio eBay
Older model: the Buchardt Audio S400 (rated 4.4/5).
Pros: Two-way design with a 3/4” tweeter on a well-implemented aluminum waveguide (compression-driver style, letting the small tweeter cross unusually low at 1800Hz), a 6” SB Acoustics-style mid-woofer, and a tunable 5x8” passive radiator adjustable via rear weights. Exceptionally flat on-axis linearity, within about ±2dB from 80Hz to 16kHz. Wide horizontal radiation for a waveguided design (about ±45-50°), notably broader than a comparable narrow-waveguide rival like the Klipsch Sevens (~±30°). Well-focused, precise imaging, aided by tight pair matching between the two speakers. Takes very well to EQ correction, letting listeners easily dial in the top end or add midrange fullness to taste. Bass extension reaches a genuine 50Hz in-room from a mellow, well-tuned rolloff rather than an artificially boosted one. Measured bass extension of 59Hz (-3dB), with a measured sensitivity of 84.7dB.
Cons: Sounds a bit bright and slightly boosted above about 7-8kHz on-axis, even with 30° of toe-out - benefits from about 1 inch of sidewall absorption at the first reflection points to tame it. A mild dullness noted especially on male vocals, alongside a small dip around 300-600Hz. Vertical positioning is critical and unusually “temperamental” - sitting even slightly toward the tweeter line causes a suckout, while sitting above it adds too much energy; not well suited to multi-height home theater seating. Distortion is fine at 86dB but runs into real issues by 96dB - not a high-output speaker. Some compression-related enhancement appears around 1.2kHz (crossover-region interaction), and the tweeter shows clear compression at 102dB. The woofer can bottom out at extreme low-frequency content played very loud; crossing to a subwoofer below 60Hz caused output problems at high volume, while 80-100Hz worked well. A subwoofer isn’t strictly required to protect the speaker at moderate listening levels (80-85dB at 3 meters), but is still recommended for genuine low-octave extension.
