The more accurate amps might be showing you the truth about the sound of your switchbox, source material, other equipment and your room. Not having seen your room, equipment and testing methods I have no idea if this is possible but as a spectator I cannot rule it out, especially when you are using 40 year old speakers. Have the Infinitys had their crossovers rebuilt? A lot of variables here.
