You keep repeating that the Emotiva emits "no distortion whatsoever."
This statement is totally untrue
, but since you don't have the knowledge base or equipment to measure the amount of distortion, you resort to hyperbole to try to continue to justify your $1,200 purchase.
Even the servo controlled Velodyne DD and DD+ series generate distortion though it is limited by the user variable servo.

Dr. Johnson shows a hand full of graphs measured at different frequencies:
Of course the $5,000 MSRP Velodyne is a much more capable sub than anything Emotiva sells, which is as it should be. The point is that great sub like the DD-18 still produces distortion.
At 15Hz and 100 db THD was 4%.
At 20Hz and 100 db THD was 2.5%
At 25Hz and 100 db THD was 2%
When the DD-18 was tested by Keith Yates, he was able to measure 10% THD at 20Hz and 115db.
All of these figures are extraordinary.
Again, the point is that given a lack of experience measuring distortion, you exaggerate the lack of distortion produced by the Emotivas. Of course Gene DellaSala talked about the overly steep 28db per octave LPF and the limiter in the Emotiva X-Ref 10. While the LPF and limiter do keep distortion relatively low, that comes at the expense of low frequency extension and output.
