Sibilance

There are different remasters of that album and they sound different. Sometimes it's hard to tell which version is being streamed.

+1.
That album has been remastered so many times it's almost impossible to know what version you are getting....

That being said, I just listened to "Time" on CD and via streaming (Amazon), and neither version I heard had any sibilance in it.

I'd say your "luck of the draw" was probably just that....lousy luck.
Unless you're hearing sibilance in most everything, I'd say it's not indicative of a problem.

I will listen to old gold CD today. 

There is none on the album.

Real sibilance is due to a lot of energy in the 3000 Hz region where our ears are most efficient. It is also a region where a lot of rooms cause trouble. Female voices and violins are frequent affected. If you have the capability putting a 2-3 db filter between 2500 and 4000 Hz will magically make sibilance disappear. 

The usual culprits are speakers, rooms and the interaction between the two.  You can see this on a frequency response curve which can be easily generated with a computer and measurement microphone. You can also see the results with added sound deadening. 

No sibilance on any of the old quad torrents, the gold MSFL or the surround SACD.
Too bad for you.
