No32,
If you're on a Mac, I found Safari does not work well with the configurator. You can make a config file, but downloading it is problematic. With Firefox, it works reliably well.
RE: SAM percentage. As I understand it, SAM makes the amp alter its output power, varying with frequency, so that the driver performs closer to its design specification. It provides some compensation for impedance and cabinet characteristics. It works from 159 Hz (?) down. It also has more effect at lower volumes. As you turn up the volume, the effect of SAM compensation decreases so that the speaker is protected from overload.
When I tried the SAM profile on my ProAc Tabletes, I found that it improved the bass, and also cleared up the vocals and midrange sounds, which I thought was very interesting. I settled at about 35%. I believe that a lot of users find that the amount / percentage of SAM they use varies with firmware version as well as their room size and listening volume. I personally found that even set at 0%, it had a positive effect on the sound overall. I'm not sure there is an absolute setting that is 'correct'. If you are usually listening at very loud volume levels, you may find that you are better off with a very low SAM percentage.
If you tell us what loudspeakers you are using, you may find others with the same or similar system who can give you more relevant opinions.
