LOL...

The traps definitely helped. I just re-calibrated things and one notable difference was that I had to lower the sub's volume control knob 25%. The 3808 had it as low as it could go (-12 db), but the LFE was still 8 - 10 db too high.

Bass in general seams tighter and more enveloping. Even my 15 year old son commented that bass sounds louder and he normally doesn’t notice things like that.

I have also found a new appreciation for just how well the QS8’s perform. With the M3 surround backs disconnected and just running 5.1, I’m doubting the need, or even felling much desire to go back to 7.1.
