No, I'm not going to route L/R thru the SMS. I am using all balanced connections on the AVM to the amp and want to keep it that way. I'll keep using the AVM XO and turn off the SMS.

Also, I am finally able to see the value of the AVM notch filter, now that I can graph it on the SMS. I have a peak near 80, so I have applied the filter on the AVM with favorable results.

The SMS is way cool, but I think it brings out the perpetual tweaker in me, never being quite satisfied. My family is growing concerned when all they hear is the SMS sweep tones for extended periods.

Can you comment on the differnt contour values of the factory presets and what affect they have. Default setting being #4, but Custom setting #5 has a different value for contour. Should I leave my default to 4 or go with 5 after I calibrate?
