I'm an analog guy, so I can't say from experience what will be best under your particular CD player.
However, I can say from experience that the best things I've heard under any other piece of audio gear are the Sistrum platforms and Audiopoints.
I'm also a firm believer in coupling and not isolation. I have been so for many years, and only recently(about a year ago) found out how good the Sistrum stuff is at achieving what I wanted to achieve.
I'm not going to fan any flames about what can and cannot work, but I will repeat that I am firmly in the "coupling" camp. I use the Sistrum stuff from one end of my system to the other. It is doing what I want it to do. As most of you know, I am very hard-core, and if it didn't work extremely well, it wouldn't be in my system.
Many times it is hard to break from a trend that has been generally accepted for years. Sometimes "doing a 180" from what you have been trying for years can pay off. This is one of those times.
A good question to ask yourselves is, "If isolation is so important, then how can this form of direct coupling with zero isolation provide such good results?" Perhaps you may conclude that there are 2 ways to control vibration in the system. In any matter of choice, there is always a winner. Do not discount the idea that this well-engineered application of direct coupling could be the winner. In my application it clearly was the winner, and I suspect it would be in many other applications also.
IMO.
Peace.
