Fiddler, you obviously have gone to great lengths regarding the tweaking to your components. However, why not provide here the same level detailed response as to how you applied the Audio Points?
To what components did you install the Audio Points under (ie rack, speakers, and all components at the same time?)?
How long a break-in period did you allow for, and perhaps most important, what racking system you used throughout this time period?
In other words, to realize the full benefits of the Audio Points, the methodology (coupling) has to be applied everywhere.
Assume for the moment that you are using zip cord for all of your cabling needs. You then install Jena Labs top of the line speaker cables, and one pair of their ic's but you leave the other pair of zip cord ic's in place.
You would probably notice a nice little improvement, but most likely not worth the $10k you just paid for these cables, and you'd probably want Jena Labs to refund your monies. But when you install that last pair of Jena Lab ic's and allow for proper burn-in, your system is now singing a whole new song.
Same principle rightfully applies when installing Audio Points (and perhaps other similar products) everywhere. However, if you are using some cheap Ikea-like coffee table, mdf boards, or even a much more expensive and popular isolation-type (de-coupling) rack for a racking system, your performance bottleneck will be the rack. You should still realize small performance gains just by installing the Audio Points, but that's the extent of the benefits.
Again, for real night and day improvements, it truly must be an all or nothing approach.
For the record, I have never seen(execpt in mags), touched, nor smelled a Sistrum rack. Small, yet noticeable, improvements were gained after installing the Audio Points under each component. But the fantastic night and day sonic improvements were only after I installed Audio Points on my own custom rack (which also adheres to the coupling methodology) and speakers and then only after about a one week mechanical break-in time period.
I'm fully aware that Y or O MMV and every system is different, but that's not the point. The point is the commitment to a complete installation to fully realize any serious benefits.
-IMO
