Optimizing Sound Quality for Stereo Sources
I purchased a new TX-NR626 about a month ago. Audio & video work just fine with the STB and AppleTV, but I am somewhat disappointed with sound quality and behavior when I use it to play stereo music out of my Itunes library using Apple TV as the go-between. It's even worse when I use an Ipod as a source. Speaker set up is L/R/center. I'm using the oRemote Ipad app to see what type of A/V source the NR626 thinks its seeing, and what mode its using to play it back. I'm using the Onkotron Ipad app to change sources/modes etc.
Itunes library music comes into the NR626 through AppleTV as PCM5 via HDMI. The NR626 defaults to "Stereo 2.1" to play it. Front L/R speakers are very good quality ADS units in excellent condition. These are the same ones I used with my old Denon stereo, but the sound quality is just not as good as it used to be with the Denon. Basically, I've not been able to adjust the treble/bass to warm up the sound enough. I'm using a digitally encoded CD as the test case.
I also want to be able to use an IPod as a source. I've connected it to the NR626's TV/CD input. When I select it, the NR626 shows it as an Analog input, and defaults to "Direct" for playback. However, the sound is very flat, and the Treble/Bass controls are unavailable. If I change from "Direct" to "Stereo 2.1", the Treble/Bass controls will work, but the sound deteriorates - there's lots of popping on strong bass notes.
I will gleefully accept any and all suggestions as to how to best set up the NR626 to improve the sound quality for these two sources.
Also, is there a web article on audio sources & playback, perhaps especially for the NR626?
