From direct experience and listening... the new changes to the Diamond Series are marked. The re-aligned bass drivers demonstrate a marked improvement in low end extension; your ears though will serve you best for what will work best for you.
Alternatively, at the new price points... buying old-stock 803D's may be a better financial option (price:performance).
