I have done a great deal of experimenting with this and find that the results are system dependant. I hear a great deal of difference with loading, and have experimented with Benz Glider, Benz Ruby and Benz Reference. Also the EMT and Koetsu.
To answer your question, I do not know what the new Benz ACE likes, but generally the higher the load (47K) the more splashy the sound and more dynamic, but with some distortion. When the number is lowered (28K) the opposite occurs. This result is based on the more expensive Benz cartridges I listed (above). The Koetsu seems to love 1K ohms exclusively, at least among all the experiments I have done.
As Marakanetz says, your OK with 47K, but if you want to experiment you might try some of the same loads to determine what the ACE responds to.
By the way, a small change such as 40K down from 47K is extremely difficult to hear, except on a ultra high resolution system.
It costs nothing to try another setting, and may be of value, even if only to learn. Be sure before you draw conclusions about load that you have the alignment, overhang, VTA, Azimuth and tracking force all set as perfect as possible. Any of these set wrong will ruin the outcome of your loading tests.
