Short answer: the ADAM Audio D3v. It ranks #3 of 47 powered bookshelf speakers by sound quality, rated 4.5/5, at $349.99; the Cambridge Audio L/R S ranks #4, rated 4.4/5, and costs $549, so there is not much of a tradeoff to weigh.
The D3v is the more accurate tiny desktop pair. Erin’s measurements show a very even midrange, spanning just 1.7dB from 300Hz to 5kHz, and its side passive radiators take the bass to 50Hz before falling 3dB. It has USB-C, analog inputs and placement filters, and comes with stands. Its limiter caps usable output around 89 to 90dB at 1m, so it is a near-field speaker.
The L/R S is the better-connected wireless pair. Its aluminum tweeter and 3-inch woofer measured very neutral on-axis with wide horizontal coverage of about 60 degrees, reaching 57Hz before falling 3dB. It adds optical, RCA, USB-C, aptX HD, app room settings and a subwoofer output. Its clean output tops out around 86dB, so it suits a desk or small room.
Buy the ADAM Audio D3v. It is rated higher for sound quality than the Cambridge Audio L/R S and costs less, so only choose the other one for a particular feature it does better.

The Two Speakers In Full
ADAM Audio D3v: $349.99 per pair Amazon $349.99 eBay
Pros: Excellent midrange linearity for a tiny desktop speaker: Erin’s Klippel data spans just 1.7dB from 300Hz to 5kHz. Side passive radiators help bass reach -3dB at about 51Hz, substantially deeper than the Genelec 8010A or Audio Smile Little British Monitor. Predicted preference scores of 5.37 standalone and 7.59 with an ideal subwoofer support it as a particularly useful compact system without a sub. USB-C, analog inputs and placement filters simplify desk setup. Measured bass extension of 50Hz (-3dB), with a measured sensitivity of 86.5dB.
Cons: A rising upper-frequency balance and vertical crossover interference keep it from being uniformly neutral at every angle; aim the tweeters toward ear height. The limiter reduces bass and midrange output as volume rises, with the existing review’s compression tests putting usable maximum output around 89-90dB at 1m. Deep bass at moderate volume should not be confused with high output capability.

Cambridge Audio L/R S: $549.00 per pair Amazon $549.00 eBay
Same family: the Cambridge Audio L/R M (larger bookshelf, estimated 4.2/5) and the Cambridge Audio L/R X (larger bookshelf, rated 4.1/5).
Pros: A 2-way active bookshelf pair built for near-field desktop use, with a 21mm aluminum tweeter and a 3-inch long-throw woofer on each speaker. Erin’s Audio Corner measured a very neutral on-axis response with good directivity control up through the 2-3kHz handoff to the tweeter, an F3 of about 57Hz and F10 of about 50Hz, and output held within roughly plus or minus 2.5dB from 80Hz to 20kHz. Its preference score is 5.08 on its own and 7.72 with an ideal subwoofer, ahead of the ADAM Audio D3v once a sub fills in the bass. Horizontal dispersion of about plus or minus 60 degrees and a vertical window of about plus 30 to minus 20 degrees make it forgiving of off-center desktop seating. Two rear switches (a desktop-placement compensation switch and a near-wall/free-space switch) plus in-app DSP for room size, wall distance, and reflective surface type let you tune the in-room response rather than just hoping placement works out, and the reviewer noted an audible tightening of the bass moving between room-size settings. Rear connectivity includes RCA, optical digital, USB-C, and a dedicated subwoofer output. Measured bass extension of 57Hz (-3dB).
Cons: Maximum clean output is limited: Erin’s Audio Corner measured about 86dB before the onboard limiter engages around 96dB to protect the drivers, so this is a near-field or small-room speaker rather than one built to fill a living room. Each speaker’s Class D amplifier splits only 50W to the woofer and 50W to the tweeter, modest for the class. The DSP room-correction options are preset-based rather than a true microphone-measured calibration at the listening position, so results depend on picking settings that match your actual room.
