Short answer: the PSB Alpha P3. Both are rated 3.3/5 for sound quality (#83 and #79 of 168 bookshelf speakers), and the PSB Alpha P3 costs $349 against $399 for the SVS Prime Satellite, so with nothing between them on sound quality, price settles it.
Why pick the PSB Alpha P3: Very compact cabinets still reach about 55Hz in the local Spinorama snapshot, while the 5.64 sub-assisted score and relatively smooth sound-power behavior make this a sensible small-room speaker. The catch: Low measured sensitivity around 81dB restricts clean output and asks more of the amplifier.
Why pick the SVS Prime Satellite: Compact 2-way satellite speaker with a 1-inch aluminum dome tweeter and 4.5-inch polypropylene midrange/woofer. The catch: Bass rolls off below 69Hz (±3dB) due to compact enclosure volume, making a subwoofer essential for full-range musical reproduction or home theater bass impact.
Buy the PSB Alpha P3. Both are rated the same for sound quality, and it costs $50 less than the SVS Prime Satellite.
About the ratings: the SVS Prime Satellite’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 3.1 to 3.5, so this verdict could change once it is measured.

PSB Alpha P3: $349.00 per pair Amazon PSB Speakers eBay
Same family: the PSB Alpha P5 (larger bookshelf, ranked higher, rated 3.6/5), the PSB Alpha T20 (floorstanding, estimated 3.9/5) and the PSB Alpha C10 (center, estimated 3.4/5).
Pros: Very compact cabinets still reach about 55Hz in the local Spinorama snapshot, while the 5.64 sub-assisted score and relatively smooth sound-power behavior make this a sensible small-room speaker. Magnetic grilles and binding posts add practical polish. Measured bass extension of 63.0Hz (-3dB).
Cons: Low measured sensitivity around 81dB restricts clean output and asks more of the amplifier. The raw 3.12 preference score and some response/directivity irregularity keep it behind the best modern compact monitors, and a subwoofer is strongly recommended.
