Short answer: the Thomann Swissonic A306. It ranks #31 of 68 powered bookshelf speakers by sound quality, rated 4.3/5, at $250; the Edifier S3000Pro ranks #60, rated 3.8/5, and costs $900, which makes this an easy call rather than a real tradeoff.
What the Thomann Swissonic A306 does well: With the treble control set to -2dB, Erin measured a 7.29 ideal-subwoofer score and 43.9Hz -3dB bass extension. The catch: The published result is not the flat-control setting: it specifically uses -2dB treble.
The case for the Edifier S3000Pro: A convenient home-listening system with digital and analog input options, avoiding the need for a separate power amplifier. The tradeoff: The substantial cabinet size requires more space than a typical desktop pair.
One note: the Thomann Swissonic A306 is no longer sold new, but at #31 of 68 powered bookshelf speakers by sound quality it still outranks most current models, so used is worth considering.
Buy the Thomann Swissonic A306. It is rated higher for sound quality than the Edifier S3000Pro and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

Thomann Swissonic A306: $250 per pair Discontinued Thomann eBay
Pros: With the treble control set to -2dB, Erin measured a 7.29 ideal-subwoofer score and 43.9Hz -3dB bass extension. This is a useful affordable monitoring option when carefully set up, with onboard controls for basic tonal adjustment. Measured bass extension of 43Hz (-3dB), with a measured sensitivity of 89.9dB.
Cons: The published result is not the flat-control setting: it specifically uses -2dB treble. Even then, the response spans 2.8dB from 300Hz to 5kHz, so balance is not as even as the leaders. Bass output and vertical listening position remain practical limitations. Discontinued.

Edifier S3000Pro: $900 per pair Discontinued eBay
Newer model: the Edifier S3000MKII. It’s likely to perform similarly, though we don’t have measurements to confirm that yet.
Pros: A convenient home-listening system with digital and analog input options, avoiding the need for a separate power amplifier. Its large cabinets and tone adjustments offer flexibility for a music-focused setup.
Cons: The substantial cabinet size requires more space than a typical desktop pair. High-resolution digital input support does not itself guarantee better sound. Discontinued.
