The SAMlab has been made in order to be as precise and reliable as the measuring tools used in the SAM® laboratory. Therefore, the measurements that the engineers made with SAM V1 and the ones they do with the SAMlab are the same.
200 speakers have been SAMmed with the version 1 in the laboratory. Thanks to the measurements used for of all of those V1 profiles, the engineers were able to create version 2 profiles of those speakers.
Therefore, there are no differences between a V2 profile of speakers SAMmed in the laboratory and a V2 profile of the same speakers SAMmed with the SAMlab.
