I'm looking forward to resolving these audio issues with the new Oppo 83, with its improved audio circuitry. Hopefully.
Regarding the discussion of Audyssey and Lyngdorf and their effects on the audio quality, here's another interesting effect of the built-in Audyssey system. - Using the Oppo 980 and an NAD with Audyssey, there is a substantial attenuation of volume levels at normal volume settings when using Audyssey. For some sources, the volume control on my NAD pre/pro, which has a range of 0 to 100, must be set all the way up to about 97 or 98 (-2 or - 3 from maximum) to provide what I consider normal listening levels. And this is very unusual for my speakers/amps, etc. When using a legacy preamp, for example, I normally set the volume at perhaps 20% of the maximum range. Whether or not this would affect audio quality, it has been my understanding that it's generally preferred to set trim levels such that your average volume settings would fall somewhere near or below the middle of the range, and that you seldom have to crank it up much beyond that middle range. I'll look forward to checking all this out with the new 83 player.
