Thanks, much appreciated
I got everything roughed in enough to check all the functions and make sure everything is working right. To answer you questions about channel levels, when playing an SACD, you do have access to on-the-fly channel level adjustment.
For the other listening modes, the DTC-9.8 is not as advanced as the Denon. IIRC about my Denon 2307, it will remember your on-the-fly levels for each source and sound field pretty much indefinitely. The Integra forgets all your on-the-fly adjustments each time you turn the unit off and resets all the levels back to zero. I haven't had time yet to fully investigate this feature since I got the system re-setup, but I did a quick check by changing a channel level then turning the unit off and the level was reset to zero. I'm pretty sure this is true of all modes. I'll check again when I have more time. I still have to clean up the wiring and return the rack to it's proper location.
Thanks to you Dave, and your partner.
You guys are right, Onkyo/Integra only have a common default channel level setup memory for all inputs and all listening modes. As for Denon which is much more elaborated, you have different settings for each listening mode which is called "Personal Memory Plus".
With Denon, if you altered the levels on the fly, they will remain store in memory, even after powering the receiver off. With Onkyo/Integra, they will revert to the original settings.
Ain't life sweet when you understand such little details but of considerable dimension as these.
Thanks again to put me on the right track.
