Don't worry! Adam A3X sounds ok, just don't expect too much bass.
The same applies to Focal CMS40 too.
If you care a lot about bass, do buy the higher models. Or if you have tight budget, you may consider to buy the small one first and buy the subwoofers from same series to match with the smaller monitors later too.
Just my 2 cents. Please go and listen yourself before you make your final decision.
