So maybe my power source or cable connections. hopefully, no issues with the amp, will check all my connection and find out the source of humming....hate it.
by the way, i have both LS50 and Focal 906 running side by side now.
you are right the 906 is a better match to the ma252, could be the room too.

The Ma252 is the best thing out there by far that McIntosh has offered as far as the performance to price ratio its incredible. You can spend way more on entry level and mass market names in there offerings into high end market and there are several good ones offered from Mainly Chinese owned companies. This unit is full out McIntosh built in U.S.A and that's something to take pride in owning.incredible sound and Value!!!

I have tested all sort of things i can test so far. and nothing work.
tested:
no input.
power cable,
different speaker,
different power point,
turn off all the power in the main except the audio power point.
test with 2 pin power plug

the humming still there as long as the speaker is connected and the amp is turned on. it's not affecting my listening at all, but still ignoring.....
may need to take back to Mc to service.......owned it for 3 months only from new....... any suggestion guys?
