Short answer: the KEF LS50 Wireless II on measured sound quality, the Edifier S1000MKII on price. The KEF LS50 Wireless II ranks #19 of 105 powered bookshelf speakers, rated 4.3/5, at $2,999. The Edifier S1000MKII ranks #81, rated 3.3/5, at $359.99, $2,639.01 cheaper.
The case for the Edifier S1000MKII: A self-powered stereo pair with optical, coaxial and analog inputs, plus high-resolution digital support, makes source switching unusually simple. The tradeoff: High-resolution input support is not a guarantee of perfect tuning, and the fixed internal amplification prevents the gradual upgrades possible with separates.
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 S1000MKII lacks. It has an adjustable EQ, which the Edifier S1000MKII lacks. The catch: The 3.0dB response span is good but not reference-leading, and dispersion still varies with frequency.
Buy the Edifier S1000MKII when the price outweighs sound quality for you, and the KEF LS50 Wireless II when sound quality outweighs the price instead.

The Two Speakers In Full
Edifier S1000MKII: $359.99 per pair Amazon eBay
Pros: A self-powered stereo pair with optical, coaxial and analog inputs, plus high-resolution digital support, makes source switching unusually simple. Consumer Reports rates its sound accurate and detailed, so it is a strong one-box alternative to separate amplifier-and-speaker systems for nearfield or small-room listening.
Cons: High-resolution input support is not a guarantee of perfect tuning, and the fixed internal amplification prevents the gradual upgrades possible with separates. These are mains-powered speakers rather than portable wireless speakers, and their size and left/right cabling need a planned desktop or stand setup. 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.
