Short answer: the Vanatoo Transparent One Encore Plus. Both are rated 4.3/5 for sound quality (#19 and #18 of 100 powered bookshelf speakers), and the Vanatoo Transparent One Encore Plus costs $699.99 against $2,999 for the KEF LS50 Wireless II, with sound quality a draw, the lower price decides it.
The Vanatoo Transparent One Encore Plus is the deeper-bass choice. Erin’s Klippel data combines a small 1.7dB midrange response span with a -3dB point around 44Hz. Its bass reaches about 42Hz before falling 3dB, against 51.3Hz for the KEF LS50 Wireless II. The catch: A mild 4-6kHz edge and a smaller 1-2kHz recession were audible in the review, so its smooth midrange summary does not mean there is nothing to improve with EQ.
The case for the KEF LS50 Wireless II: 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 Vanatoo Transparent One Encore Plus lacks. The tradeoff: The 3.0dB response span is good but not reference-leading, and dispersion still varies with frequency.
Buy the Vanatoo Transparent One Encore Plus. Both are rated the same for sound quality, and it costs $2,299.01 less than the KEF LS50 Wireless II.

Older model: the Vanatoo Transparent One Encore (ranked lower, rated 3.9/5).
Pros: Erin’s Klippel data combines a small 1.7dB midrange response span with a -3dB point around 44Hz. Scores of 5.57 standalone and 7.38 with an ideal subwoofer make it an attractive standalone system as well as a subwoofer partner. Remote tone controls, multiple digital and analog inputs, and automatic subwoofer crossover engagement simplify setup. Measured bass extension of 42Hz (-3dB).
Cons: A mild 4-6kHz edge and a smaller 1-2kHz recession were audible in the review, so its smooth midrange summary does not mean there is nothing to improve with EQ. No HDMI ARC. Deep bass and louder playback still benefit from a subwoofer; amplifier wattage alone does not establish clean room-filling output.

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.
