I'd like to see the Millenia cranked up just to see what overtones it produces when pushed . Maybe a more meaningfull test might be to increase signal level until each unit shows a specific amount of fundamental , then compare the higher order bumps .
REW has the abillity to output IMD test tones built in , under 'generator' ,multitone, dualtone ,
