Short answer: both are discontinued, so this only matters if you are buying used. Used, the Thomann Swissonic A306 is the better pick: it ranks #52 of 113 powered bookshelf speakers by sound quality (rated 4.3/5), against #99 (rated 3.8/5) for the Edifier S3000Pro. If you want one new, the Edifier S3000MKII replaces the Edifier S3000Pro and is rated 3.9/5 at $799.49.
The Thomann Swissonic A306 is the better-sounding pick. With the treble control set to -2dB, Erin measured a 7.29 ideal-subwoofer score and 43.9Hz -3dB bass extension. The tradeoff: 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.
Buy the Thomann Swissonic A306 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the Edifier S3000MKII, which replaces the Edifier S3000Pro.

The Two Speakers In Full
Thomann Swissonic A306: $250 per pair Discontinued Thomann eBay
Older model: the Thomann Swissonic A305 (rated 4.2/5).
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, ranked higher, estimated 3.9/5.
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.
