Yes, sibilance can be eliminated.
Absolutely NO, it is NOT the price you pay with high detail digital playback. It's the price you pay with poor digital playback.
The problem is that most CDPs are still relatively poor performers, even many of the high-priced models. The Meitner blows away many other high priced digital pieces not just because it's great, but because many of the pieces it replaces or compared to are relatively poor.
Why do you think that we have more CDP modders than anything else? Most stock CDPs just won't cut it in a system where the rest of the equipment is at a high level. The result is a high sibilance, fatiguing and unsatisfying system where the user then makes the mistake of blaming the recording because some recordings can expose sibilance worse than others. Even worse, you find many people addressing the problem going down the cable or other equipment swapping road to nowhere.
Yes, you can diminish some sibilance through power conditioning and maybe a tad through vibration control, but, generally, nothing compares to the amount of sibilance generated through most digital playback. The funny thing is that most people (including myself) accepted it and/or don't realize it, until you hear truly great digital playback.
My advice is don't accept sibilance as a natural product of digital. The bad thing is that it's going to cost you and will be tough to find either through mods or stock equipment. However, in the long run, it will save you much more time, money and aggravation.
