See how you go with some critical listening and see if you feel the SQ has changed at all.

Oh Drat!

There is a reduction in SQ. Given conditionally as the comparison is a bit tricky as it takes a volume adjustment to try to keep the comparison apples to apples, my wife with the more critical ears than my older models says there is a slight reduction in detail. I would describe it as if someone put a cardboard box over my speakers. Not a huge difference, but noticable. Darn it, after all the expense of my last tweak to get that last bit of SQ, I just can't cut it back. But now that I have heard how useful this levelling is for me, the cat is out of the bag and I don't want to be without it. Darn, darn, darn.
