Short answer: the ADAM Audio A77H. Both are rated 4.4/5 for sound quality (#45 and #44 of 118 powered bookshelf speakers), and the ADAM Audio A77H costs $2,799.98 against $3,099.98 for the ADAM Audio A8H, and with sound quality even, the cheaper one is the better buy.
The case for the ADAM Audio A77H: Horizontally configured true 3-way studio monitor featuring dual 7-inch MLM woofers, a dedicated 3.5-inch midrange, and a rotatable X-ART tweeter. Watch for: Rating estimated based on A-Series sibling measurements.
What the ADAM Audio A8H does well: Flagship 3-way studio monitor in the ADAM Audio A-Series featuring a handmade German X-ART ribbon tweeter in a rotatable HPS waveguide, a 3.5-inch DCH dome/cone hybrid midrange, and an 8-inch Multi-Layer Mineral woofer. Watch for: Rating estimated from measured ADAM Audio A7V and ADAM Audio A4V Klippel NFS datasets.
Buy the ADAM Audio A77H. Both are rated the same for sound quality, and it costs $300 less than the ADAM Audio A8H.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: ADAM Audio A77H 4.2 to 4.6; ADAM Audio A8H 4.2 to 4.6). Treat this verdict as provisional.
