After NOT seeing any significant differences in the usual D2, D3, and D4 distortion measurements above between the Orion and Andromeda (which sounds notably clearer and more articulate), I decided to run these on a hunch. Actually, the hunch thing is bullshit. I already knew. Those of you guys who have known me for a long time know that I always play the cards close to my chest and leave an ace up my sleeve. These are FFTs of 500Hz tones at about 89db....
