bracurrie, I also have a system that seems to my ear to be be as true to reproduction as I have ever heard. I have a Scott 299D tube amp hooked to Cornscala's and a very good dedicated Marantz CD player. The problem I feel you're having is the same as mine. I believe it has to do with how the CD's are mastered. I have a Stowkowski remastered cd that was highly rated by Amazon critics and I hear hiss at the beginning and end of each Beethoven piece (orig. recorded in 1957) I put up with it because the music itself is of a very high quality. On the other hand my #1 test cd for showing off my speakers is Bernard Herrmann's "Mysterious Island" cd which was recorded just a few years ago and is super quiet before and after each song. { Fabulous recording, by the way } so, to sum up, the older recordings will have a bit of hiss where the newer ones , if they are good, will not.
Another example of a different kind is I purchased, again on the advice of Amazon critics a recording of Chopin's Nocturnes by M. Paolini (i think that's how you spell it) and when I popped it in, I heard a fairly nice recording of Chopin, except that next to the pianist it sounded like Dennis Hopper from "Blue Velvet" was sitting next to him breathing through his emphysema/asthma machine at full blast! Not Good! I suppose it was a bad placement of a microphone. I now see that some new Amazon critics since I purchased it have said pretty much the same thing - they must be owners of Klipsch speakers!
