Often times a tizziness, digital-like hash, or grainy highs can often be interpreted as an intollerable 'treble brightness'.
This can be the result of poorly designed ics and speaker cables, usually those that induce time-smear. Some silver cables will introduce a certain tizziness.
But unconditioned lines can and will also introduce its own sonic harm in much the same way along with the negative sibilance you mentioned.
If none of your components are properly conditioned and you're using a digital source, then there is an excellent chance that the bi-directional digital noise that is generated is also infiltrating your other components. For that you need to make certain that any line conditioner you purchase is also bi-directional to keep the noise from going back into the AC line back to the service panel and then into your other components.
So if you're concerned about certain aspects, don't assume that fixing one fixes all.
Not all line conditioners will reduce or eliminate negative sibilance or prevent digital noise from going back into the line. For this and other benefits, I would recommend the Foundation Research LC-1 and LC-2 passive and dedicated in-line power conditioners that come with their own built-in power cable. New they sell for $795 (for front end source components) and $995 for the amp. Used these should be right around your budget.
Among other benefits, the Foundation Research line conditioners should eliminate all negative sibilance induced by noisy AC. But keep in mind there are certainly negative induces occurences of sibilence embedded in the recording itself via the microphones or others. There is no line conditioner that can remove this type of negative sibilance.
With regard to ics and speaker cables and a grainy digital hash-like sound resulting from a time smear, some to many cables have this unwanted characteristic.
If per chance you are also experiencing these effects, then you might want to consider the Audience Au24, Paul Speltz' Anti-cables and Anti-ics, or the Audio Tekne lines of ics and speaker cables.
