Thanks for sharing this generalhead. I did not realize that AVRs were designed like this. That said, I am struggling to understand the design logic here. While I can totally appreciate pure 2.0 sources should only go to the front speakers when in Direct or stereo more, switching the receiver to ProLogic II or DTS Neo or ALL channel stereo should redirect some of the bass to the sub.
I have very large front speakers and they sounds very bassy even at a bass setting of only +2, that said, they are no match for my 12" 450 watt RMS sub which brings in the bottom end and just rocks my home theater room...feels like a night club in there. Are there really front speakers that could match the bass of a dedicated subwoofer? I doubt it as the 607 puts out 90 watts x2 to the fronts which is less than half of what the sub gets. Heck, even the biggest professional DJ speakers still have a dedicated subwoofer(s) somewhere is the setup and they mostly play 2.0 sources.
Oh well. At least I know now not to but CDs anymore. I ripped the CD to MP3s and now play it over via my netbook over RCA to the 607 and all sounds good...as good as the CD in terms of crispness and definitely more bassy :-)
