I want to connect my Rega Ear headphone amp (h-amp) to a Denon 3805 surround receiver. What I want to do is: When I connect the headphone, I want to be able to mute the speakers (this is necessary, because I don't want to disturb my neighbours. Besides, I don't want the speaker sound to 'interfere' with the headphone sound). But so far I haven't been able to get this to work. I've read the manual and tried connecting the h-amp to the tape out connectors on the Denon (choosing Zone 2 as signal output), and this works fine with analog sound, but not with digital sources (as stated in the manual). I've also tried pre-out, but then I can't prevent the sound from going to the speakers as well. I also want to be able to adjust the volume using Denon's remote control (this isn't a 'requirement', but it would be very practical). Does anyone (3805 owners with first-hand experience?) know if it's possible at all to connect a headphone amp to the Denon 3805 and mute the speakers, without muting the signal sent to the h-amp? Your help and suggestions would be greatly appreciated!
