Many have and agree with your results.

Glad you are happy with your adjustments, like you said who cares if you are breaking audiophile laws, as long as you like it then do it.

Although I found the A1400 with the M80s to be very enveloping in direct 2 channel/no sub.

Did you try the surrounds at 100hz as well?
