Sibilance in recordings: your experience the same?


I have just finished a remodeling project and added new 20amp lines to feed my system. Rather suddenly I became annoyed with excessive sibilance on Patricia Barber's Mythologies recording (CD). I had never noticed this before. I looked at my system configuration and could find no obvious changes in the pre/post-remodeling arrangement of my power cords and ICs, so I have to ask if others have had the same experience with this recording. While I'm at it, are there other recordings, say, in the female singer/songwriter genre with inherently excessive sibilance? The really annoying thing about sibilance is once you hear it, YOU REALLY HEAR IT!

And yes, I agree, sibilance, particularly the artificially created kind, is extremely annoying. When it occurs, I can no longer listen until the cause is corrected.
Almost forgot, the sibilance could also be partially due to lack of burn in, settling time on new AC lines, I've found a lack of refinement in newly installed lines. I could also be in the recording, you'll have to play a lot more cds in order to determine recording or system at fault.
Thank you gentlemen. I'll stick with the current arrangement for awhile. Starts me thinking about these new power lines. I've seen some pretty ridiculous threads on burn-in (volume knobs??) so I won't even go there...for now. Really...what's the current literature say about that?
Sibilance due to settling time on new AC lines is just as ridiculous as burning in volume knobs so take what you read with a grain of salt.

Given the factors above are attended to, I have found better digital analyzing or decoding, eliminates much of the after edge from voices.

At times it can be difficult to tell if it's entirely the recording, the artist's enounciation, or the replay gear itself.

Reba mcEntire's voice is one of the best on the planet, superior range, emmotive, and evocative. however many of her recordings don't seem to be done with better audio replay gear in mind. Alan Jackson is in the same camp, production wise.

I feel the producer of the album is largely responsible too for artifacts in it's content. though keep in mind whose audience these recordings are targeted for as to the why of it. It wasn't long ago that some genres were mixed in such a way as to be replayed, primarily on a single speaker car radio... or just boom boxes. R&B, Rock, Blues, Pop, etc.

Bluegrass & Folk, for instance is not far removed from being tilted more towards a content oriented sector. Today that same group of devotees are older and consequently possess better replay devices. Add in further refinements in electronic recording gear, and today's 'grass by and large, sounds excellent regardless the level of gear.

Top tier artists also usually get better studio efforts... though not always.

If you pay attention to the producer of the great sounding albums more so than the artists, you'll find you amass a better level of quality recordins in your library.
