gallaine: you say that you thought you had solved your sibilance problem but then it returned. what did you do, or perceive that you had done, to "solve" your problem? you have a complex system comprised of many parts. each of those parts "reacts" to every other in the chain. finding the weak link is no easy task, as well you know. i suspect the annoying sibilance emanates from the match or mismatch between your transport and dac. i would also suggest you have overly bright interconnects for your component, although you say you've tried changing them out. did you substitute copper interconnect between EVERY component, SIMULTANEOUSLY? if you didn't, i'd suggest you somehow arrange to do so. i empathize with you. sooner or later, we each hear a mouse in the works we can neither see nor capture. have patience and continue your quest. i'm sure you will eventually capture and tame the little beast. -kelly
What is the cause of my sibilance problem?
I have been fighting a sibilance problem for about a year. I thought I had it beat but it is back. I've tried cleaning and treating all connections, acoustic foam treatment at first reflection points on side and front walls and ceiling, different interconnects, speaker position, and even a different digital front-end. The problem manifests itself as extremely harsh 's' sounds in both male and female voice. I am beginning to wonder if I need to have my hearing checked - I tried headphones and hear the same problem. Well, here is my system:
Aiwa XC-37M CD-changer
MSB Link DAC III with 24/96 upsampling board
B&K Ref. 10 preamp
B&K AV6000 poweramp
Paradigm Reference Studio 60 Loudspeakers
Hsu Research VTF-2 powered subwoofer
Signet center channel
Atlantic Technology surrounds
Sennheiser HD580 Headphones
Home Grown Audio Super Silver interconnects
Monster Cable subwoofer cable
Ted's Excellent Cable speaker wire (mains)
Kimber 4TC speaker wire (surrounds)
Mapleshade Brass cones, weights, and cork/rubber feet
Michael Green 5-shelf Audio Rack.
A Television, the subwoofer, and the Audio Rack sit between the louspeakers; which are approximately 7' apart and 7' from the listening position. My room is highly irregular and ASC claims that $1200 in acoustic treatment is the answer to my problem. I'm not saying they are wrong. But, having experienced the same problem with headphones (and acoustic foam not alleviating the problem one iota) I am beginning to wonder...
