Ok, I went back and looked at the documentation and the night mode only affects dolby digital signals so that is out as a possibility. I’ve done a lot of experimenting with stereo signals as well.

Obie_fl thanks for the input. Yes, the Yamaha will play significantly louder than the 990 using the same settings (as best as I can match them up). And no, I don’t regularly listen to anything that loud. I stopped where I did because I really didn’t want to destroy anything, my speakers or my hearing. My point was that I could run the 990 at 100% and I don’t think I should be able to approach that with this setup.

For the record, I’m running Klipsch KG4.5 speakers with a Klipsch KSW12 sub. These are pretty efficient speakers so I would think the 755 would drive them to those kinds of volumes with no trouble at all. I’m running the mains as large, the center and rear (5.1) as small. I’ve tried several crossover frequencies but, I know from experience around 80hz gives the smoothest transition from the mains to the sub so, that’s what I settled on. At the moment, I’m using the speaker in my Toshiba DW65X91 set for center and some small Infinity’s in the rear. This system has evolved from a stereo system to home theater over the years. A new set of speakers are next on the list of upgrades.

By the way obie_fl, awesome home theater!!!

Paratrooper, thank you as well. I’ve gotten a lot of good use out of the RX-V795 but it was lacking in some respects now. (I’ve only been using it for 6 years now) Let me ask you, would you think that you could ever run your 990/755 system at 100%? Honestly, I would expect to blow out a speaker doing that if the 755 was really being driven close to 200watts/ch. But I can set the 990 at +8db (won’t go any higher, I now know from personal experience) and everything holds together, no clipping, no distortion, woofers don’t lose control or bottom, no smoke for the tweeters

I guess a call to tech support is in the future for me. I really want this to work but right now, I’m not satisfied. And, honestly, I don’t think it is working correctly. I’ve gone through a lot of gear over the years. I’ve run these same speakers and RX-V795 with a Yamaha M80 stereo amp for years. So, I have an idea what a high power/quality amp should be able to do with them.

Oh, I tried a reset on the 990 but no joy there either.
