It would be a nice to have a dimensions to have with or without something. For example, amplifiers may say Dim Height with feet is X , Dim Height without feet is Y. Same for TV's etc. Second request would be BTU and Amperage draw. There should be minimum, mid and max values. When doing a large-scale project, if we put max for everything, the BTU would require such a large AC unit that it becomes ridiculous. In our industry, no one runs amplifiers at 100% all the time.
