Sdrconsultant: First you say that you will try to be objective and then the first comment is to dismiss NBS because he used to work as a car salesman (perhaps being a car salesman should be included as part of the criminal record!) Did you even know that Mark Levinson didn't even have an engineering degree? ( I think that he didn't even have a college degree) Maybe we should dismiss his Levinson and Cello products also! Some companies hire engineers to do their research, have you considered that?
