Short answer: the KEF LS50 Wireless II if sound quality matters most, the Edifier S1000W if price matters most. The KEF LS50 Wireless II ranks #18 of 100 powered bookshelf speakers, rated 4.3/5, at $2,999. The Edifier S1000W ranks #79, rated 3.3/5, at $419.98, $2,579.02 cheaper.
What the Edifier S1000W does well: Network playback and multiple digital and analog connections make it a convenient all-in-one music system. The tradeoff: High-resolution input support does not itself improve acoustic accuracy.
The KEF LS50 Wireless II is the better-sounding pick. Erin’s measurements give preference scores of 5.43 standalone and 7.51 with an ideal subwoofer, with a -3dB point around 51Hz. It keeps a wired aux input, which the Edifier S1000W lacks. It has an adjustable EQ, which the Edifier S1000W lacks. Watch for: The 3.0dB response span is good but not reference-leading, and dispersion still varies with frequency.
Buy the Edifier S1000W if the price matters more than sound quality. Buy the KEF LS50 Wireless II if sound quality matters more than the price.

Pros: Network playback and multiple digital and analog connections make it a convenient all-in-one music system. Support for high-resolution input is useful for compatibility with different sources.
Cons: High-resolution input support does not itself improve acoustic accuracy. The all-in-one format offers less component flexibility than separate speakers and amplification. No independent measurements exist; reviews are limited to informal listening comparisons.

KEF LS50 Wireless II: $2,999.00 per pair Amazon KEF Crutchfield eBay
Same family: the KEF LSX II LT (smaller bookshelf, ranked lower, rated 4/5), the KEF LSX II (smaller bookshelf, estimated 4.1/5) and the KEF LS60 (floorstanding, rated 4.8/5).
Pros: Erin’s measurements give preference scores of 5.43 standalone and 7.51 with an ideal subwoofer, with a -3dB point around 51Hz. The coincident Uni-Q layout helps preserve tonal consistency across horizontal and vertical listening positions. Low listening-window narrow-band deviation of 0.308 supports relatively clean midrange reproduction. HDMI eARC and streaming functions make it a capable all-in-one stereo system. Measured bass extension of 51.3Hz (-3dB).
Cons: The 3.0dB response span is good but not reference-leading, and dispersion still varies with frequency. Compact bass drivers limit deep-bass output. App placement adjustments are not the same as microphone-based automatic room correction. The price and primary/secondary architecture are practical trade-offs; neither driver geometry nor a single directivity statistic guarantees the best sound in every room.
