Short answer: the Audio First Cadentia 3 if sound quality matters most, the SVS Prime Bookshelf if price matters most. The Audio First Cadentia 3 ranks #7 of 216 bookshelf speakers, rated 4.7/5, at $7,199. The SVS Prime Bookshelf ranks #145, rated 3.5/5, at $699, $6,500 cheaper.
The Audio First Cadentia 3 is the more accurate, deeper-bass option. Near-textbook measurements: excellent on-axis linearity, listening window, and directivity, with only minor deviations. Its measured preference score, a predictor of how neutral it sounds, is 7.55 against 5.17 for the SVS Prime Bookshelf. Its bass reaches about 43Hz before falling 3dB, against 72Hz for the SVS Prime Bookshelf. The catch: A mild scoop through the upper midrange/lower treble slightly softens the attack of snares, hand claps, and sibilants: fixable with a single-band EQ (2.5kHz, +1dB, Q~1).
Why pick the SVS Prime Bookshelf: Reasonable sensitivity for the price at about 87dB, and the 6.5” woofer sits in its own dedicated sealed sub-compartment inside the cabinet for cleaner midrange/bass separation. Watch for: A scooped mid-range paired with a boosted upper mid-range creates an audibly uneven tonal balance, and there’s an additional dip in the treble around 4-5kHz that reads as slightly tinny relative to the recessed mid-range.
Buy the Audio First Cadentia 3 if sound quality matters more than the price. Buy the SVS Prime Bookshelf if the price matters more than sound quality.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared. The two were measured by different sources, so small differences, especially in the bass, can come from the measurement setup rather than the speakers.

Pros: Near-textbook measurements: excellent on-axis linearity, listening window, and directivity, with only minor deviations. Extremely low distortion and compression, holding steady even at 102dB with barely any loss. Very wide, consistent horizontal dispersion (~70 degrees) gives a big, enveloping soundstage with strong image specificity outside the speaker boundaries. Strong bass extension for a bookshelf (F3 43Hz, F10 26Hz) with a punchy, guttural mid-bass. Measured bass extension of 43Hz (-3dB), with a measured sensitivity of 86.4dB.
Cons: A mild scoop through the upper midrange/lower treble slightly softens the attack of snares, hand claps, and sibilants: fixable with a single-band EQ (2.5kHz, +1dB, Q~1). High-frequency dispersion narrows quickly above about 4kHz, so off-axis listeners lose some air and detail. Very high asking price for a bookshelf-class speaker, and the complete (finished) version has a long lead time; the loaner kit version ships as an unfinished cabinet you assemble and finish yourself.

SVS Prime Bookshelf: $699.00 per pair Amazon $699.00 eBay
Same family: the SVS Prime Satellite (smaller bookshelf, estimated 3.3/5), the SVS Prime Tower (smaller floorstanding, estimated 3.6/5), the SVS Prime Pinnacle (larger floorstanding, estimated 3.8/5), the SVS Prime Center (center, rated 3.4/5) and the SVS Prime Elevation (surround, estimated 3.3/5).
Pros: Reasonable sensitivity for the price at about 87dB, and the 6.5” woofer sits in its own dedicated sealed sub-compartment inside the cabinet for cleaner midrange/bass separation. Overall response stays within about ±3dB from 80Hz-16kHz, which the reviewer calls reasonable for the price point. Wide, consistent horizontal radiation. Toeing the speakers 30 degrees off-axis smooths the in-room response noticeably if the on-axis tonal balance isn’t to your taste. Measured bass extension of 72Hz (-3dB), with a measured sensitivity of 87dB.
Cons: A scooped mid-range paired with a boosted upper mid-range creates an audibly uneven tonal balance, and there’s an additional dip in the treble around 4-5kHz that reads as slightly tinny relative to the recessed mid-range. Measured minimum impedance dips below 4 ohms (EPDR even lower), so an 8-ohm-only amplifier or AVR may struggle: a 4-ohm-stable amp or separate amplification is recommended. Bass extension is modest (F3 72Hz, F10 49Hz measured): SVS clearly designed this to be paired with one of their subwoofers rather than to stand fully alone. Compared directly against its pricier sibling, the SVS Ultra Bookshelf, in the same review, the reviewer found the Ultra noticeably more tonally neutral.
