Nice assessment, Plato.
As one who dabbles with performance-oriented racking systems utilizing the resonance energy transfer (aka coupling) methodology, my limited experience tells me that as you said any product's performance can be influenced(sometimes for the better, sometimes for the worse) via chassis tweaks.
My take on the chassis tweaks would be to eliminate or minimize the dampening within the chassis and instead tightly couple all internal components to the chassis which in turn should be tightly coupled to the racking system which in turn should be tightly coupled to the sub-flooring system.
Thus providing an expedited exit path for the air-borne vibrations captured instantaneously but which can only dissipate over a period of time (like a reverb).
The more tightly coupled everything is, the more instantaneous the mechanical transfer occurs.
I find it frustrating when mfgers of otherwise good performance-oriented equipment make half-assed attempts at internal vibration control and internal line conditioning. First, the consumer is forced to select that mfgers choice of methodology (which is often times an inferior methodology) and second, its usually through some cheap $5 part like a tiny AC filter or a certain silicon glue or dampening plate and third, theres usually nothing the consumer can do to rectify the mfgers poor choice or futile attempts since the methodolgy is often times so embedded into the product.
So in my opinion that otherwise well-crafted product is now deemed worthless or worth less in my book.
Anyway, thats my take.
-IMO
