    I have a Denon 3802 and I notice hiss when I play cd's at higher volumes (-10 and up) and it is noticible during quiet parts of the tracks... When I pause the DVD player that is playing the CD's, I hear no hiss nor do I hear hiss at full volume when there is no cd playing. This is a key fact since I understand that this is normally then pointed at the source material. The Hiss is also less on DDD recordings.
    The thing is: When I demoed the same track on a marantz 7200 with the same speakers in the store I heard very little hiss... Could this be anything in the system? Do some components magnify the source hiss when taking older recordings (like the Star Wars: ESB soundtrack special edition I demoed) and others lower it?

    Here's my system for playing the 2-chan CD's:
    Paradigm Monitor 11 v3 Mains
    Denon 3802
    Panasonic RP62 (DVD & CD Player) - AR Optical Interconnect
    Home Depot 12' Spkr wire w/ monster twist banana plugs

    are you using an analog or a digital connection? When you pause the source using a digital connection, the 3802 will mute the output which is why you hear no hiss. Try setting the reciever to analog, pause the source, turn it up to -10, and check for the hiss.

    Using analog I also get no hiss when the volume is full (aside from a normal less than 1-foot away hiss)- so the reciever should be fine as far as the amp is concerned...

    Could the dvd, pre/pro, or speaker wire introduce the hiss while the music is playing?

    Would a line conditioner help like a Monster Power 1000/2000?

    Well the store I auditioned at was a sound proofed room and whisper quiet. Perhaps I am just being a bit more picky now that I own them.

    I guess I could always give a line conditioner or noise canceller a shot if it will help lower the hiss from the tweeter...

    Gary: the stores system and your home system are very different.

    First - disconnect your CATV cable from your system. Does the hiss go away? The CATV feed often injects noise into the electronics ground.

    Second - try disconnecting all other sources to the receiver. Does the hiss go away? if so, re-connect each device and test to find which one is injecting noise.

    Hope this helps.

    The only thing I have connected is a brand new dvd player optically...
    The CATV and everything else is not run through the receiver

    I wonder if I should just preorder the 3803 instead...those better DAC's should help correct?
