This is for owners or those who are familiar with these units. I was looking into getting one of these receivers to replace my aging Sony. When I was browsing through the owner's manual of both of these units, I saw this: Muting of PRE OUT jacks, HEADPHONE jack and SPEAKER terminals The PRE OUT jacks, HEADPHONE jack and SPEAKER terminals include a muting circuit. Because of this, the output signals are greatly reduced for several seconds after the power switch is turned on or input function, surround mode or any other-set-up is changed. If the volume is turned up during this time, the output will be very high after the muting circuit stops functioning. Always wait until the muting circuit turns off before adjusting the volume. Forgive my ignorance, but does this mean that if I change the surround or sub levels, instead of hearing the difference in levels immediately, it will mute then come back on after a while? Will this also be the case if I decided to switch 'on the fly' my dvd soundtrack (e.g. dolby to dts)? Also, does this multi-second muting happen when non-Denon dvd players switch layers?
