I was thinking exactly the same thing when I read his review. All processors have the problem of using digital speaker calibration. But all processors may not have the -3dB. I think enough folks have confirmed V4 has that -3dB compared to direct wired. But someone should check a V6. Very easy to do. Just a spl meter and a test tone on a CD or music server.

Calibrate v6 to all 0, large
Set speaker to any level, say 70
Measure test tone in direct DSP preset mrc bypassed
Now unplug left/right main and connect direct to source.
Measure again with speaker at 70

If it measures higher by 3dB it can use the tweak.

In fact I would suggest targeting as close to 0dB until someone measures it on V6.

If you think listening to music is fun, try learning an instrument.
