I know the company is called THAT Corp,  and I think they are in 
Massachusetts.  I worked in the hearing test equipment industry for several years, 
and we used these for the purpose of dynamic ranges of 100+ dB and 
low THD (don't remember exact specs) .   They weren't particularly inexpensive, I recall.
