XMC 2.1, dirac left/right level weird/wrong

[zealott]

Hi,
I have two XPA-1 from 2017 powering my 802D's, where one of the amps are 6-7db lower in volume than the other.
Intl shipping and weight is the reason I have not returned them for repair, they work fine other than that.

on my XMC-1 , the Dirac compensated for that volume discrepancy and no problems.

Now, on my XMC-2 (fw 2.1), it finds the same level difference, and after Dirac calibration my test-tones show the same volume level (with an SPL meter), but when I listen to music it favored the left speaker (with the amp that is louder).
I did a re-run of the Dirac calibration, and now it favour the other side (basically I manually adjust the levels afterwards to get the sound centered, and no, my ears as just as good on both sides).

Any hints, thoughts?
Thanks,
John

Do you have a sound level meter so you can adjust the trims manually?

[zealott]

Yes, I have. But the weird thing is that the SPL levels are fine, example:
Uncorrected, left front 60db, right front, 53db.
Corrected with Dirac, both are equal (53db) when running test tones. However, to get the sound properly centered, I have to manually adjust and it sounds wrong.

Perhaps I should do a level trim on the channels before running dirac in case they are to far apart for the algorithms to compensate properly?
