Short answer: the JBL 305P MKII. Both are rated 4.3/5 for sound quality (#18 and #20 of 105 powered bookshelf speakers), and the JBL 305P MKII costs $289 against $699.99 for the Vanatoo Transparent One Encore Plus, so with nothing between them on sound quality, price settles it.
Why pick the JBL 305P MKII: Erin’s Klippel data gives 5.38 standalone and 7.52 with an ideal subwoofer, with bass reaching -3dB around 51Hz. Watch for: The 3.3dB midrange span and rising response show it is not perfectly neutral.
The Vanatoo Transparent One Encore Plus is the deeper-bass pick. 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 50Hz for the JBL 305P MKII. The tradeoff: 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.
Buy the JBL 305P MKII. Both are rated the same for sound quality, and it costs $410.99 less than the Vanatoo Transparent One Encore Plus.

The Two Speakers In Full
JBL 305P MKII: $289.00 per pair Amazon eBay
Older model: the JBL LSR305 (ranked lower, rated 4.2/5). See every JBL 3 Series generation.
Same family: the JBL 306P MKII (larger bookshelf, rated 4.1/5) and the JBL 308P MKII (larger bookshelf, rated 4.4/5).
Pros: Erin’s Klippel data gives 5.38 standalone and 7.52 with an ideal subwoofer, with bass reaching -3dB around 51Hz. Broad horizontal coverage and reasonably smooth reflected sound support stable imaging across a desk. The existing review reports effective limiting and little sustained thermal compression, making it a strong budget-monitor option rather than just a speaker with a promising frequency curve. Measured bass extension of 50Hz (-3dB), with a measured sensitivity of 91.1dB.
Cons: The 3.3dB midrange span and rising response show it is not perfectly neutral. A port-related feature around 1.6kHz and some excess treble can be audible; the review recommends the treble-trim switch. Vertical crossover interference makes ear height important. Amplifier hiss may matter in very quiet nearfield use, and rear-port placement needs room-boundary adjustment.

Vanatoo Transparent One Encore Plus: $699.99 per pair Amazon eBay
Older model: the Vanatoo Transparent One Encore (ranked lower, rated 3.9/5). See every Vanatoo Transparent One generation.
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.
