Hmmmm.....
I would agree that a Denon receiver is not the best preamp/amp component for two channel listening, but there still shouldn't be noticeable increased noise level or hiss, or whatever you are getting. I have a Denon receiver myself and have used it with TRL digital sources (SOny 595, Marantz SA14) with no problems.
Since you say it is only on female vocals and guitar reverb I now am unclear what exactly it is you are hearing.
Is is extreme sibliance on vocals? Is it unatural fizz on the electric guitars? Is it background noise level?
If it is not on every disk, that is confusing to me.
I guess you could try a different preamp/amp combo if you can also.
