ok this is my second different unit in a month. the first one blew up in a big way after 10mins. the second one now cuts out when the volume is turned up. after a thurough testing it is only when i have ANY channel settings on that use the rear surrond channels, the speakers or the channel don't even need to be used for it to cut out. if i select a setting that won't allow me to use the rear surround channels like sterio and a couple of others the volume goes up no probs with no cut out at all. there must be something wrong with these new models for this to happen twice even though it was 2 different faults(or was it). the unit will go back to empiredirect and i'll get my money back and won't get another denon again.i thought they were a good make. anyone heard of this cut out prob before???. thanx for any replies. BJ.
