As far as downmix goes, surely if a Bluray offers a 2.0 mix I just choose that and always ensure (obviously) my AVR is set to 2.0
agree, just had a look at nr1506 manual
does not seem to say what adjustment you have of the mix if you were inputting the multi-channel and driving two speakers.
[- usb capability looks nice, maybe use @ demo
- could not see if it supports internet radio dash/hls streams eg. BBC
- wondered whether people use the Audyssey Dynamic volume&Eq funtionality, to ensure voices remain discreet
(apparently for all makes when Audyssey engaged, output sampled 48Khz, due to cpu/processing requirement)]
