Laughter is good for the soul: glad you are enjoying the thread. 

For me I haven't come to any conclusions because I cannot compare the two 
outputs. 

However, using logic tells me the new mono output has significantly less 
info than its foundation camera, the M240. Spending $8k for less data isn't 
real funny to me and I'm not sure I trust Leica or its paid talking heads.

Can you share with me/us how you determined the difference is imperceptible?
