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 #54 of 119 powered bookshelf speakers by sound quality (rated 4.3/5), against #102 (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 $999.97.
The Thomann Swissonic A306 is the better-sounding pick. Affordable studio monitors with useful bass and tone controls that make a capable budget setup when carefully tuned. The tradeoff: The published result is not the flat-control setting: it specifically uses -2dB treble.
The case for the Edifier S3000Pro: A large powered pair with digital and analog inputs and tone controls, a complete music system with no separate amplifier needed. 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.
