Mdrummer01 - I had the same problem on Barber and many other recordings (my system is very revealing). I changed tweeter's in-series cap from $10 variety to $100 variety and most of sibilants disappeared. Amplifier distortions also convert to sibilants - my previous SS was "brassy" and less clean. Cheaper tweeters might have small resonances in 8-11kHz range where sibilants are.
Audphile1 - I also use Acoustic Zen cables, Satori Shotgun and Absolute IC.
