Hi Icehawk, grunt, JohnK and all,

Somewhere in my distant memory I read a piece about why this happens with Dolby PLII(x) in the Music mode. The same thing happens on my H/K AV receiver when I switch from Logic7 or dts Neo:6 to DPLII Music mode--a boost of about 6 to 10 dB in the sub level. I can't recall if this is an error in the Dolby algorithm or an error in implementation of the Dolby decoder by, in my case, Harman/Kardon. I know that Dolby licensees are given quite a lot of flexibility in how they install Dolby processing modes in their products.

More research is needed. I still have a contact at Dolby Labs, and at H/K, so I'll send off an email and see what comes back. I think I read about this in a thread on another forum.

There will be an update. . .

Regards,
Alan
