Short answer: the Buchardt A10. It ranks #12 of 119 powered bookshelf speakers by sound quality, rated 4.7/5, at $4,300; the HEDD Type 20 MK2 ranks #26, rated 4.5/5, and costs $4,798, so there is little reason to consider the other one.
Why pick the HEDD Type 20 MK2: Three-way studio monitors with balanced mids, useful deep bass, and switchable ported or sealed bass for different needs. The tradeoff: These results are for ported operation, not every bass or phase setting.
The Buchardt A10 is the more accurate pick. Active stand-mount speakers with accurate sound, deep bass for their size, and selectable DSP tunings to suit your room. Its measured preference score, a predictor of how neutral it sounds, is 7.28 against 6.11 for the HEDD Type 20 MK2. Watch for: The rising treble balance can sound brighter on axis; toe-out or a different tuning may suit some rooms.
Buy the Buchardt A10. It is rated higher for sound quality than the HEDD Type 20 MK2 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
