"Grainy" highs problem...

Hello All,

I am relatively new to the hi-fi audiogon crowd. Actually, I've just been out of the hobby for about 15 years, and I just got the bug again. I've been upgrading my system over the last six months and have heard some GREAT improvements. My system consists of some custom made speakers by Van L Speakerworks, a Cary Cinema 11 pre-pro, Cary Cinema 5 amp, Eichmann interconnects, mid priced monster speaker wire,Better Cable coax dig cable, and a Pioneer Elive DV-37 source. Since upgrading to the Cinema 5, I have noticed so much more detail and clarity, and realism. It's wonderful. But, it seems to have also added a problem. My highs are really extended, but have a grainy texture. Obviously, my source is a week link in this setup (though, I'm actually using the DACs on the Cinema 11) What can I do to remedy this situation, cost effectively? Eventually I will uprgade my source (looking at a McCormack UDP1) but can't afford to do it now. Should I try different interconnects or speaker wire? Or is this grainyness just inherent in Red Book CDs? Any thoughts or suggestions? I'd really love to 'smooth' this problem out without losing any of the remarkable detail. Thanks so much!
